It’s hard to luck into a .300 batting average, but that is pretty much what happened with my bold predictions. Two of the three calls I got right — Jose Quintana’s high ERA and Nick Castellanos‘ admittance into the 25-homer club — could be at least partially explained by this season’s home run explosion. The remaining seven predictions did not age well, but they have given me new perspectives on several players, including Yuli Gurriel and Jean Segura.
1. Tom Koehler will be roughly as valuable as Matt Moore.
Moore lived down to expectations, but Koehler was still far less valuable than he was. Koehler’s slider, which was key to an extended run of success in 2016, was not an effective pitch for him in 2017. His O-Swing rate on the pitch dropped substantially, from 44.7 to 34.2 percent, and his slider strikeout rate went down, while his Iso went up. Those trends ultimately led to Koehler’s ouster from the Marlins’ rotation, though it provided him with a fresh start in the Blue Jays’ bullpen.
