A’s Acquire Reliever, Like Always
It’s July, which means the A’s are trading to improve their bullpen. Whether it’s Jake Diekman, Mike Minor, Jeurys Familia, or any of a seemingly unending number of other moves, they always seem to find an arm they can bring in to redo their leverage roadmap and provide a little extra playoff oomph. Last night, they acquired Andrew Chafin in exchange for Greg Deichmann, Daniel Palencia, and cash, as MLB.com’s Mark Feinsand first reported.
Chafin has been downright spectacular this year. In 39.1 innings, he’s allowed only nine runs, good for a 2.06 ERA. He’s done so by limiting home runs; he’s only given up one all year, and while that’s unlikely to persist, he does plenty of things right that should continue to limit homers. He gets grounders, with a 50% groundball rate so far this year. He’s limited hard contact, too: opponents have barreled up only 5.1% of their batted balls and have hit only 32.3% of them 95 mph or harder.
Do those two things, and homers are harder to come by. Baseball Savant’s xHR, which is a descriptive estimate of home runs based on contact quality, thinks Chapin “should” have allowed only 1.1 dingers so far this year. That doesn’t mean it will keep happening — it’s based on the actual contact allowed, which is volatile — but it’s a good sign that he hasn’t given up 20 warning track blasts or anything of that nature.
