Jack Flaherty
American baseball player (born 1995)

Jack Rafe Flaherty (, born October 15, 1995) is an American professional baseball pitcher for the Detroit Tigers of Major League Baseball (MLB). He has previously played in MLB for the St. Louis Cardinals, Baltimore Orioles, and Los Angeles Dodgers. Flaherty was selected by the Cardinals in the first round of the 2014 MLB draft and made his MLB debut with them in 2017.
Amateur career
Flaherty attended Harvard-Westlake School in Los Angeles, California, where his pitching coach was future MLB pitching coach Ethan Katz. He pitched and played shortstop and third base as a member of the varsity baseball team for all four of his years at Harvard-Westlake. He was a sophomore when two of his high school teammates and fellow pitchers, Max Fried and Lucas Giolito, were both drafted in the first round of the 2012 MLB draft. In 2013, as a junior, Flaherty pitched a 13–0 record with a 0.63 ERA, striking out 112 batters in 89 innings while only walking 10. During his senior season, Harvard-Westlake was the consensus #1 team in the nation in the MaxPreps "XCellent 50" for much of the beginning of the season, before dropping out of the rankings altogether.
Flaherty played for the United States national team at the 2013 18U Baseball World Cup, pitching 10+1⁄3 innings to help win the Gold Medal in the tournament.

Why this record matters

Chronology provides the most reliable spine for this subject; interpretation should follow only after identities and dates are secure. The source revision retrieved here is dated Sep 22, 2026. The linked authority identifier is Q17182711. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1995, 2014, 2017 and 2012.
A concise life account rarely captures disputed attribution, private networks or the changing language used to describe a career. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
