Mike Foltynewicz’s Slow Start
After years of inconsistent production, Mike Foltynewicz finally harnessed his elite fastball and emerged as an All-Star in 2018. Across 183 innings, Foltynewicz struck out 202 hitters while notching a 2.85 ERA and a 3.37 FIP. All of those marks were easily career bests and, perhaps most impressively, he managed to miss tons of bats while also increasing his ground-ball rate. One year doesn’t make an ace, but Foltynewicz’s stock surged as much as anybody’s in baseball last season.
But Foltynewicz hasn’t built off his breakout campaign in 2019. The right-hander started the season on the disabled list, didn’t look quite right when he rejoined the rotation, and has yet to resemble his 2018 form in anything more than short bursts.
Across 10 starts this year, he’s posted a 5.53 ERA and a FIP north of 6.00. After striking out nearly 10 hitters per nine innings last season, he’s now whiffing fewer than eight. Even worse, Foltynewicz’s home run rate has tripled in 2019, and his 2.44 HR/9 ratio is the fifth-worst in the league among pitchers who have thrown at least 50 innings.
There are a few factors that explain Foltynewicz’s plummeting numbers. As always, velocity is the first thing to check when a pitcher suddenly starts getting hit around, and sure enough, Foltynewicz is down a bit relative to last season. Read the rest of this entry »
