That's not ideal.
Per FanGraphs pitch values, the Oakland A's have the second worst slider in baseball, behind only the ever so sad Padres. Thank heavens for the Padres.
This is a simultaneous contradiction of unsurprising and surprising. The A's are terrible and for months, started Eric Surkamp every fifth day. Of course their sliders are terrible. But if I told you back in March that the A's, a team that has featured baller sliders like Sonny Gray's and Chris Bassitt's, would be at nearly their worst when throwing those pitches, it wouldn't make a lot of sense.
