Over 1,600 players reached 50 innings pitched during the 2019 Minor League Baseball season, from Triple-A all the way down to the various Rookie ball circuits. Out of all of those pitchers, a Marlins prospect ranked sixth overall in terms of strikeout percentage—sixth—and you may not even know his name. That prospect is reliever Alex Vesia, a 2018 17th-round draft pick from NCAA Divison II Cal State East Bay.
You will not find Vesia on MLB Pipeline's Top 30 Marlins prospects list, but you will find him in the bullpen during the Arizona Fall League's Fall Stars Game on Saturday.
