Jesus christ he's currently rocking a FIP of 8.77 with a *gulp* 22.6% GB rate and a 15.8% HR/FB rate. That's a bad combo. Oh wait, he also has a walk rate of 8 per 9. Wouldn't want any solo homers!
Fastball velocity is down to 93.2MPH (over 95MPH last year) and has currently been -4.4 runs below average on his heater this year.
Him and Giolito are both running out of excuses. The diminished stuff is one thing, the inability to command and control pitches is another. Lopez has a little more margin for error given he was actually decent last year but Giolito was literally league worst.
After all the pitcher injuries the inability of these two guys to get out of their own way has probably been the biggest non Manny disappointment in the rebuild.
