I confess that I haven’t watched many Marlins games this year. The team is projected to have the third worst record in baseball, potentially losing 100 or more games for just the third time in organization history. They average fewer than 10,000 fans per home game, the lowest in the league in 2019, which would be an all-time low, surpassing the 2018 season. It’s been a bumpy ride for Don Mattingly’s rebuilding Miami club.
But the Marlins do have some interesting players who are capable of doing interesting things not many other players are capable of doing. After Caleb Smith’s solid outing this past weekend, I spent some time perusing Statcast and discovered that, among left-handed pitchers who have thrown a minimum of 50 four-seam fastballs in 2019, Smith’s has the third most horizontal movement in the game. Right behind him is his teammate, Adam Conley. One spot ahead of him is Chris Sale. And one spot ahead of Sale, leading all 113 lefties in this sample in horizontal movement, is Smith and Conley’s teammate Jarlin Garcia.
Three of the top four left-handed big leaguers in four-seam horizontal movement all pitch for the Marlins.
That piqued my interest. In 2018, Garcia was one of the worst pitchers in baseball, carrying a -1.3 WAR and 6.37 FIP in 66 innings pitched. His xwOBA-against and xSLG-against were both in the first percentile in the league. In 2019, Garcia’s strikeout rate is up, his walk rate is down, and as of this writing, he has contributed 0.4 WAR and has a 3.79 FIP. What seems to be the likeliest cause of this improvement? His fastball’s horizontal movement was still 98% better than league-average last year, but its value was -1.57 wFB/C. This year it is 110% better than league average and its value has been 0.86 wFB/C. What changed more than his fastball movement, however, was his slider movement and usage:
