I dunno the walks and homers have given him a 4.39 FIP and a 3.86 xFIP. He's a really good pitcher and has been pretty darn good but the homers have been a bit of an issue. Edit: His BABIP was .256 going into today since the trade. 3.73 xFIP and 3.97 FIP after today. Homers have been a bit of a problem, but 3 came in one game when he clearly wasn't quite right. Plus the small sample size hasn't given him enough time to off-set that. He's always done a good job of limiting homers, too. I'm not worried about it too much. Me neither. He's been really good overall since they brought him over. I haven't looked at his heat maps from this year but I bet you he's been nibbling a bit more this entire season than he has in the past, which has led to the higher BB%. The homers are still mostly from the juiced ball and Paul Goldschmidt being Babe Ruth the moment he sees the Cubs logo.
