Reid Kristien Detmers (born July 8, 1999) is an American professional baseball pitcher for the Los Angeles Angels of Major League Baseball (MLB).

Detmers was born in Nokomis, Illinois, and attended Nokomis High School as well as Glenwood High School, lettering in baseball for four seasons between the two schools. He played college baseball at the University of Louisville for three seasons, earning Atlantic Coast Conference and national accolades by his sophomore season. In his junior year, Detmers was considered one of the top prospects for the MLB draft. He was selected tenth overall by the Angels in the first round of the 2020 draft and signed with the team, forgoing his final year of college eligibility.

After pitching only 14 games in the Angels farm system, Detmers was promoted to the major leagues in August 2021. He made the 2022 Opening Day roster with his rookie eligibility still intact. On May 10, 2022, Detmers threw a no-hitter, becoming the youngest pitcher in Angels history to do so.{{cite news|last1=Schoenfield |first1=David |title=Angels rookie Detmers throws no-hitter vs. Rays |url=https://www.espn.com/mlb/story/_/id/33895223/los-angeles-angels-rookie-reid-detmers-throws-no-hitter-tampa-bay-rays |work=ESPN |language=en |date=May 11, 2022 |access-date=December 9, 2022}} On July 31, 2022, he threw an immaculate inning, joining Mike Fiers and hall-of-famer Sandy Koufax as the only pitchers to throw both a no-hitter and an immaculate inning in the same season, and the only member of the group to do so as a rookie.{{cite web|first=Rhett|last=Bollinger|url=https://www.mlb.com/news/reid-detmers-immaculate-inning-dominant-start-vs-rangers|title=Detmers joins Koufax, Fiers with immaculate feat|date=August 1, 2022|website=MLB.com|publisher=MLB Advanced Media|language=en-US|access-date=September 11, 2022|archive-url=https://archive.today/20220911150912/https://www.mlb.com/news/reid-detmers-immaculate-inning-dominant-start-vs-rangers|archive-date=September 11, 2022}}

Pitching style

Detmers relies primarily on the four-seam fastball, using it nearly half the time in his first two major league seasons. He also uses a slider, curveball, and changeup as secondary pitches.{{cite web |title=Reid Detmers Statcast, Visuals & Advanced Metrics |url=https://baseballsavant.mlb.com/savant-player/reid-detmers-672282?stats=statcast-r-pitching-mlb |website=Baseball Savant |publisher=MLB Advanced Media |access-date=December 9, 2022}}

As a prospect, MLB Pipeline scouts graded Detmers's fastball at 55, slider at 50, curveball at 60, changeup at 50, control at 55, and overall profile at 55 on the site's 20–80 scale. Detmers struggled with his slider while at Louisville, but credited Angels coaching with helping him adjust the pitch when he entered the organization.{{cite news |last1=Terranova |first1=Rob |title=Scouting report: Angels' Reid Detmers |url=https://www.milb.com/news/scouting-report-angels-reid-detmers |access-date=December 9, 2022 |work=Minor League Baseball |publisher=MLB Advanced Media |date=June 29, 2021}} Following a mechanics adjustment during a minor league stint in July 2022, Detmers saw improved results with his slider and began using it as his strikeout pitch.{{cite news |last1=Valenzuela |first1=Sarah |title=Reid Detmers' 12 strikeouts and immaculate inning can't save Angels from another loss |url=https://www.yahoo.com/lifestyle/reid-detmers-12-strikeouts-immaculate-235040143.html |access-date=December 9, 2022 |agency=Los Angeles Times |publisher=Yahoo! |date=July 31, 2022}}
