:Madison Bumgarner

Madison Kyle Bumgarner was born August 1, 1989, in Hickory, North Carolina, and grew up in an area ten miles northwest nicknamed "Bumtown" because of the abundance of people with the surname Bumgarner who have lived there over the years, after their ancestors had arrived from Germany.{{cite web |last=Adelson |first=Eric |url=https://sports.yahoo.com/news/giants-pitcher-madison-bumgarner-is-from-a-place-nicknamed--bumtown--almost-a-century-ago.html |title=Giants pitcher Madison Bumgarner is from a place nicknamed 'Bumtown' almost a century ago |work=Yahoo!

At the age of four, he began playing youth baseball league, for which his father had to sign a waiver because the league was for five- to eight-year-olds. He would not let Madison throw curveballs until he was sixteen. His parents, Kevin and Debbie, divorced while Bumgarner was in high school.

Bumgarner attended South Caldwell High School in Hudson, North Carolina, where he was known as "Maddie" and played on both the school's baseball team and the Post 29's American Legion Baseball team. In his junior season, he had a 12–2 win–loss record, an 0.99 earned run average (ERA), and 120 strikeouts in 84 innings pitched as he helped his team to a runner-up finish in the 2006 4A State Championship. The next season as a senior, he went 11–2 with a 1.05 ERA and 143 strikeouts in 86 innings, helping his team win the 2007 4A State Championship.{{cite web |last=Haft |first=Chris |url=http://mlb.com/news/article.jsp?ymd=20070607&content_id=2011321&vkey=draft2007&fext=.jsp |archive-url=https://wayback.archive-it.org/all/20100120090031/http://mlb.com/news/article.jsp?ymd=20070607&content_id=2011321&vkey=draft2007&fext=.jsp |url-status=dead |archive-date=January 20, 2010 |title=Giants go young in Draft's first round |publisher=MLB Advanced Media |date=June 7, 2007 |access-date=March 6, 2014 }} He hit .424 with 11 home runs and 38 runs batted in (RBIs). He was named most valuable player (MVP) of the playoffs and the Gatorade North Carolina Player of the Year, garnering the nickname "The Carolina Peach." Bumgarner attracted so much attention from scouts and agents in high school that his father built a wall around the bullpen at his high school field to keep them from distracting him as he warmed up. He committed to attend the University of North Carolina at Chapel Hill on a college baseball scholarship.

In 2013, the North Carolina High School Athletic Association included Bumgarner on its "100 To Remember" male athletes list, which included Michael Jordan, Carl Eller, and Jim Beatty.{{cite news |url=http://www.hickoryrecord.com/sports/article_06263574-20d4-11e3-920d-001a4bcf6878.html |title=Former South Caldwell pitcher Bumgarner on elite list |newspaper=Hickory Daily Record |date=September 18, 2013 |access-date=March 29, 2014}}

The San Francisco Giants selected Bumgarner in the first round, with the tenth overall selection, of the 2007 MLB draft. Going into the draft, Baseball America had ranked him as the 14th-best prospect overall. He was the first high school pitcher to be selected as the Giants' first pick since Matt Cain in 2002, and the first left-handed pitcher selected in the first round by the organization since Noah Lowry in 2001. Bumgarner was also the first left-handed pitcher taken as the first pick by the organization since Mike Remlinger in 1987, the first high school left-handed pitcher the Giants drafted in the first round since Frank Riccelli in 1971, and the first high school left-handed pitcher taken as the first pick by the organization since Riccelli in 1971.

Bumgarner pitched for the Augusta Greenjackets, the Giants' Low-A South Atlantic League affiliate, in 2008. The Giants had him alter the angle of his head during delivery, but after Bumgarner struggled over his first three starts in Augusta, he reverted to the way he had thrown in high school. With Augusta, he worked on his changeup, slider, and ability to throw effectively on the inside part of the plate, a critical trait for a pitcher with his side-armed delivery. He won the South Atlantic League pitchers' Triple Crown, tying for the league lead in wins (15, tied with Levi Maxwell), leading the league in ERA (1.46), and leading the league in strikeouts (164).{{cite web |url=https://www.baseball-reference.com/minors/leader.cgi?type=pitch&id=73b8a932 |title=2008 South Atlantic League Pitching Leaders |work=Baseball-Reference.com (Minors) |access-date=May 15, 2013 |archive-date=September 15, 2013 |archive-url=https://web.archive.org/web/20130915050941/http://www.baseball-reference.com/minors/leader.cgi?type=pitch&id=73b8a932 |url-status=live }} He began the 2009 season with the Giants' High-A affiliate, the San Jose Giants of the California League. After five starts, in which he went 3–1 with a 1.48 ERA and 23 strikeouts, he was called up to the Giants AA affiliate, the Connecticut Defenders of the Eastern League. On July 22, he hit a grand slam against Eric Niesen and picked up the victory in a 9–3 triumph over the Binghamton Mets.{{cite news |url=http://www.norwichbulletin.com/x889021966/Bumgarner-hits-grand-slam-as-Defenders-snap-skid |title=Bumgarner hits grand slam as Defenders snap skid |newspaper=Norwich Bulletin |date=July 23, 2009 |access-date=March 29, 2014}} In 20 games (19 starts) with them, he went 9–1 with a 1.93 ERA and 69 strikeouts.{{cite web |url=https://www.baseball-reference.com/minors/player.cgi?id=bumgar001mad |title=Madison Bumgarner Minor League Statistics & History |work=Baseball-Reference.com (Minors) |access-date=March 5, 2014 |archive-date=February 3, 2014 |archive-url=https://web.archive.org/web/20140203011159/http://www.baseball-reference.com/minors/player.cgi?id=bumgar001mad |url-status=live }}

In 2008, Baseball America ranked Bumgarner the third-best prospect in the Giants organization.{{cite magazine |last=Baggarly |first=Andy |url=http://www.baseballamerica.com/today/prospects/features/265340.html |title=Baseball America Top 10 Prospects List |magazine=Baseball America |date=December 14, 2007 |access-date=March 6, 2014|archive-url=https://web.archive.org/web/20170801004434/http://www.baseballamerica.com/today/prospects/rankings/organization-top-10-prospects/2008/265340.html|archive-date=August 1, 2017}}

Entering 2010, Bumgarner attended the Giants' spring training before the season, competing for the position of fifth starter. He dropped to the fourteenth-best prospect in baseball on the magazine's list, as some writers were concerned about a drop in Bumgarner's velocity.{{cite magazine | url=http://www.baseballamerica.com/today/prospects/rankings/top-100-prospects/2010/269546.html | title=Top 100 Prospects: No. 1-20 | magazine=Baseball America | date=February 23, 2010 | access-date=August 14, 2012 | archive-date=November 3, 2012 | archive-url=https://web.archive.org/web/20121103001848/http://www.baseballamerica.com/today/prospects/rankings/top-100-prospects/2010/269546.html | url-status=live }} Out of shape entering the new season, he struggled and was sent down to the AAA Fresno Grizzlies, partly due to his loss of velocity.{{cite web |last=Grey |first=Jason |url=https://www.espn.com/fantasy/baseball/flb/story?page=60F6I090922 |publisher=ESPN |title=What's wrong with Bumgarner? |date=September 22, 2009 |access-date=June 24, 2019 |archive-date=May 18, 2017 |archive-url=https://web.archive.org/web/20170518193052/http://www.espn.com/fantasy/baseball/flb/story?page=60F6I090922 |url-status=live }}Baggarly, pp. 189–191 In 14 starts with Fresno, he went 7–1 with a 3.16 ERA and 59 strikeouts.

On September 8, 2009, the Giants promoted Bumgarner to the major leagues for his debut in a start against the San Diego Padres at AT&T Park that night. He started in place of ace Tim Lincecum, who was scratched with back spasms. At the age of twenty and thirty-eight days, he became the second-youngest pitcher ever to start a game for the Giants, older only than Mike McCormick, who started two games for the Giants—as a nineteen-year-old—in 1956, when the team was still in New York.{{cite news |title=Headley leads Padres past Giants |url=https://www.usatoday.com/sports/baseball/2009-09-08-padres-giants_N.htm |date=September 8, 2009 |newspaper=USA Today |agency=Associated Press |access-date=September 9, 2009 |archive-date=September 12, 2009 |archive-url=https://web.archive.org/web/20090912052526/http://www.usatoday.com/sports/baseball/2009-09-08-padres-giants_N.htm |url-status=live }}{{cite web |url=http://sanfrancisco.giants.mlb.com/news/article.jsp?ymd=20090908&content_id=6863468&vkey=recap&fext=.jsp&c_id=sf |title=Bumgarner solid, but Giants lose ground |access-date=September 16, 2009|last= Haft |first=Chris |date=September 9, 2009|publisher=MLB Advanced Media|archive-url=https://web.archive.org/web/20171201131435/http://m.giants.mlb.com/news/article/6863468|archive-date=December 1, 2017}} In the bottom of the third inning with no outs, Bumgarner struck out Padres' pitcher Kevin Correia for his first career strikeout.{{Cite web|url=https://bleacherreport.com/articles/250957-a-star-is-born-madison-bumgarner-makes-shocking-but-successful-debut|title=A Star Is Born: Madison Bumgarner Makes Surprising but Successful Giants Debut|first=Bleacher|last=Report|website=bleacherreport.com}} As a rookie, Bumgarner's locker was next to that of future National Baseball Hall of Fame starting pitcher Randy Johnson in his last MLB season.{{Cite web|url=https://www.nytimes.com/2020/03/05/sports/baseball/madison-bumgarner-diamondbacks.html|title=Landing Madison Bumgarner Gave Arizona an Ace and a Mentor (Published 2020)|date=March 5, 2020}} Bumgarner made four appearances with the Giants in 2009, posting an ERA of 1.80 and striking out ten batters in ten innings.

On June 26, 2010, Bumgarner was called up again to join the club, facing the Boston Red Sox the next day, where he registered his first career Major League hit. He replaced Joe Martinez, who had made one start in place of an injured Todd Wellemeyer, in the starting rotation.

The Giants would play the "Wild Card" in the National League Division Series. On October 11 at Turner Field, in a 3–2 win over the "Wild Card" Atlanta Braves, his childhood team, Bumgarner made his postseason debut in Game 4 of the 2010 National League Division Series (NLDS), striking out five and pitching six innings to advance the Giants to the National League Championship Series (NLCS).

Bumgarner walked two while allowing only three hits and permitting just one Ranger to reach second base, winning his first career World Series game. He became the first National League rookie starting pitcher to pitch five scoreless innings in a World Series game since John Stuper of the St. Louis Cardinals in Game 6 of the 1982 World Series against the Milwaukee Brewers. Bumgarner had a chance to become the first rookie pitcher to throw a complete game shutout in a World Series game since the Cleveland Indians' Gene Bearden blanked the Boston Braves 2–0 in Game 3 of the 1948 World Series, but Bumgarner had already thrown 106 pitches. Instead, he turned the ball over to the closer Brian Wilson, who led the Majors that season with a franchise record-tying 48 saves and finished Game 4.

This was the first complete game shutout by a pitcher in a World Series game since the Florida Marlins' Josh Beckett in the clinching Game 6 of the 2003 World Series over the New York Yankees at Yankee Stadium. This was also the first by a left-handed pitcher since Johnson in Game 2 of the 2001 World Series over the New York Yankees at Bank One Ballpark.

After the game, when asked how many pitches he might be able to throw tomorrow night, Bumgarner said "Maybe 200?"{{Cite web|url=https://www.sportingnews.com/au/mlb/news/2014-world-series-game-7-tim-hudson-madison-bumgarner-200-pitches-giants-royals-jeremy-guthrie-james-shields/1c621frujdl3n1urupvsxev0mn|title=Hudson to start, Bumgarner ready for '200 pitches' as infinite baseball beckons | Sporting News Australia|date=October 29, 2014|website=www.sportingnews.com}} On October 29 at Kauffman Stadium, before Game 7 of the World Series, Bumgarner sat and stood in the outfield with fellow starter Jake Peavy discussing the game plan strategy. Bumgarner said Hudson would pitch a few innings, hand the ball over to himself, and then he would hand it off to the bullpen. Peavy instantly countered and predicted that Bumgarner would not have to come out and that he would finish the championship. Reliever Jeremy Affeldt, who relieved Hudson, pitched a scoreless bottom of the fourth. The bullpen gates opened and Bochy and the Giants brought in Bumgarner on two days' rest to protect their one-run 3–2 lead in the fifth. This was Bumgarner's first appearance out of the bullpen since Game 6 of the 2010 NLCS, when he also relieved Affeldt. After allowing a single in the fifth inning to second baseman Omar Infante, whom the Giants defeated in a series during their three World Series championship runs, Bumgarner retired 14 batters in a row. The game ended in dramatic fashion when, with two outs, left fielder Alex Gordon lined an {{convert|87|mph|adj=on|abbr=on}} slider to left center field. Center fielder Gregor Blanco misplayed the ball, and it rolled to the wall. Left fielder Juan Pérez had trouble grabbing the ball, which allowed Gordon to reach third base as the potential tying run, on a base hit and error combination. With the tying run {{convert|90|ft}} away and the winning run at the plate, Bumgarner was continually "climbing the ladder" with Posey, who was half-squatting and nearly standing. Bumgarner threw six pitches to catcher Salvador Pérez, inducing a foul pop up fly ball, which was caught by third baseman and free agent to-be Pablo Sandoval to end the game, Series, and baseball season.{{cite web|url = http://usatoday.com/story/sports/mlb/2014/10/29/world-series-game-7-royals-giants-dynasty/18153359/|title=Dynasty: Giants win third World Series title in five years|date= October 30, 2014 |work=USA Today|access-date=October 30, 2014}} This win made the Giants the first visiting team since the 1979 Pittsburgh Pirates to win Game{{nbsp}}7 of the World Series,{{cite news |last1=Waldstein |first1=David |title=Bumgarner, a Three-Ring Master, Leads San Francisco to its Third Title in Five Seasons |url=https://www.nytimes.com/2014/10/30/sports/baseball/world-series-2014-giants-beat-royals-in-game-7-to-win-title.html |website=The New York Times |date=October 30, 2014 |access-date=January 6, 2020}} continuing their "Even-Year Magic," a trend of clinching World Series titles while on the road, having done so at Globe Life Park in Arlington in {{wsy|2010}} and Comerica Park in {{wsy|2012}}.

He also lowered his career earned run average at home to 2.71, also a ballpark record and the lowest in its two-decade, 20-season history (minimum 20 games started) among Giants starting pitchers.{{Cite web|url=https://www.sfexaminer.com/sports/giants-ace-bumgarner-fans-nine-padres-in-another-oracle-gem/article_17abf81f-629c-5ed5-ad99-9aa15c93ce50.html|title=Giants ace Bumgarner fans nine Padres in another Oracle gem|first=Andrew|last=Tan|date=August 30, 2019|website=San Francisco Examiner}}{{Cite web|url=https://www.mercurynews.com/2019/08/30/bumgarner-remains-elite-at-home-yastrzemski-matches-a-cepeda-feat-in-giants-win/|title=Bumgarner remains elite at home, Yastrzemski matches a Cepeda feat in Giants win|date=August 31, 2019}}{{Cite web|url=https://www.sfchronicle.com/giants/article/Giants-Bumgarner-dominates-Padres-homers-from-14403922.php|title=Giants' Bumgarner dominates Padres; homers from Belt, Yastrzemski}}

Bumgarner's repertoire consists of four pitches including a curveball he throws at two different speeds with two different types of movement. He features a four-seam fastball with an average velocity of 92.22 mph, a cutter that averages 87.77 mph, and a curveball that averages 77.45 mph with a sharp, mostly downward break. Occasionally, he throws a much slower curve with a more exaggerated and horizontal break that averages 70.25 mph, and he also throws a change-up that sits at an average of 84.51 mph. He tends to throw the fastball and the cutter over 30 percent of the time (exact percentage varies from year to year), and the change-up and curveball are his secondary pitches.{{cite web |url=http://www.brooksbaseball.net/landing.php?player=518516 |title=Player Card: Madison Bumgarner |publisher=brooksbaseball.net |access-date=March 6, 2014 |archive-date=April 4, 2014 |archive-url=https://web.archive.org/web/20140404203004/http://www.brooksbaseball.net/landing.php?player=518516 |url-status=live }}

So last October, Madison put together a string of performances that I think is pretty hard to believe--and I'm not talking about his locker room celebrations. Twenty-five years old and is already one of the best pitchers in postseason history. For his career, he's 4-0 with a [0].25 ERA in the World Series. Last year, he set a new record for postseason innings pitched. And of course, there's Game 7, which is what kids in their backyards dream about. Madison comes in from the bullpen on just two days' rest after throwing a complete game shutout in Game 5. He throws five more scoreless innings to wrap up the title with one of the greatest performances in World Series history."

On February 23, 2020, Bumgarner revealed in an interview for The Athletic that he has competed in rodeo events as a team roper under the alias Mason Saunders, combining a shortened version of his first name with his wife's maiden name. He said that he had been roping since his mid-teens—long enough that "it's part of who you are"—and he has been discreetly competing in rodeos for some time, including during his MLB career. Bumgarner, who added that he was frequently recognized at rodeo events, won over $26,000 in a competition in Wickenburg, Arizona about two weeks before he signed his Diamondbacks contract, and said that he may pursue roping more seriously after the end of his MLB career.{{Cite web |date=February 23, 2020 |title=Madison Bumgarner reveals rodeo hobby: 'Just part of who you are' |url=https://www.espn.com/mlb/story/_/id/28768282/madison-bumgarner-reveals-rodeo-hobby-just-part-are |url-status=live |archive-url=https://web.archive.org/web/20200224024310/https://www.espn.com/mlb/story/_/id/28768282/madison-bumgarner-reveals-rodeo-hobby-just-part-are |archive-date=February 24, 2020 |access-date=February 23, 2020 |website=ESPN.com|agency=Associated Press}}
