Jhoulys Chacin has been a fairly effective starting pitcher for much of his career. He had a poor year in 2014, but his 2016 which he split between the Angels and Braves wasn’t what it appeared on the surface. His 4.81 ERA wasn;t backed up by his 4.01 FIP. Chacin was just unlucky. The Padres figured that too and Chacin pitch well for them in 2017. The Brewers followed suit and he was very effective. His second year with the Brewers didn’t go so well and here is Chacin on a minor-league, no risk deal with the Red Sox.
Unfortunately, Chacin is probably less unlucky in 2019 than he’s just been ineffective. His 5.69 FIP isn’t much behind his 5.79 ERA. However, his 1.93 HR/9 rate is wildly out of character for Chacin, and his xFIP (which uses a normalized HR/9 rate) is 5.24. Another thing in his favor is a higher than normal BABIP (batting average on balls in play) of .308, compared to a career .281. While StatCast sees batters hitting him harder than they have in awhile, it is fair to say Chacin has been slightly unlucky on balls in play.
The projections aren’t really kind to Chacin, but there is good news.They basically see him as a roughly, if slightly below average, starting pitcher for the rest of the year. At the very least, Chacin will eat some September innings. The hope is that Chacin pitches a bit above average, as he has in the past, giving him a boost going into free agency. I personally like Chacin and if he impresses, I wouldn’t be surprised if the Red Sox try to bring him back.
