He really struggled with the heat (specifically 4 seamers) last season too more so than sliders. Per Statcast, he had a +5 RunValue against sliders and wasn't really missing a lot of chase pitches. My guess is that he continues to miss fastballs, which is a shame because he used to be a good fastball hitter.
