Now that the minor league baseball season has ended, we’re continuing our look at how the St. Louis Cardinals’ top prospects (including Redbirds) performed in 2016.  Last time, we profiled the #5 prospect: SS Delvin Perez.

Now we turn to #4 prospect, Jack Flaherty.

Jack Flaherty  RHP
6’4”, 205 lbs. 
Bats-Right, Throws-Right.
Harvard-Westlake High School in Southern California had two pitchers selected in the first-round of the 2012 major league baseball draft, and two years later Harvard-Westlake’s Jack Flaherty was also drafted in the first round. 

Flaherty played third base and pitched in high school, and although some teams viewed him as a hitter, the Cardinals liked him as a pitcher--where he has played throughout his minor league career.
He started 2014 with Carolina in the rookie Gulf Coast League, where he pitched 22.2 innings. He gave up 18 hits, walked 4, and struck out 28, only allowing a .209 batting average.
Promoted to the Midwest League in 2015, Flaherty pitched 95.0 innings and struck out 97 batters, with a 2.84 ERA and a 9-3 win-loss record. Had he thrown enough innings to qualify, he would have finished 9th in the league in ERA.
2016 saw Flaherty advancing to the Florida State League, where he pitched 134.0 innings. His ERA rose to 3.56, giving up 129 hits and 45 walks, with 126 strikeouts.
Flaherty’s fastball is average or slightly better, and with him only concentrating on pitching since high school, there may be room for improvement as he matures. His changeup is his best pitch; he is capable of throwing it with good deception. He throws both a slider and a curve, with the slider being more advanced than the curve, although neither stands out.
Flaherty should be assigned to AA Springfield of the Texas League in 2017.  He has a chance to have three or four average or above-average major league pitches, and profiles as a solid #3 or #4 starter in the future.
