If you only do a cursory glance at their numbers, yes, Pelfrey has looked "better" (still awful). But dig into the numbers a bit more and a different story is told. Worley BABIP: .401 (incredibly unlucky) Pelfrey BABIP: .368 (very unlucky but looks like a lottery winner compared to Worley) Worley HR/FB: 15.5% (LOL, ouch) Pelfrey HR/BB: 6.8% (absurdly low and will only trend upward) Worley GB: 47.1% Pelfrey GB: 40.1% (given that he only puts the ball on the ground four of ten times, expect many balls to start leaving the park) All of that translates to... Worley xFIP: 4.83 Pelfrey xFIP: 5.33 Worley has pitched very badly this season. Pelfrey has pitched worse, only he's slightly luckier than Worley. Nothing about watching Mike Pelfrey makes me think he's going to succeed this season. It was a good gamble but it was just that... a gamble. He shouldn't continue to get playing time if he continues putting up horrendous numbers while also magically avoiding home runs (something a pitcher has very little control over). I'm not against the Worley demotion because he's pitching like crap, as evidenced by his mid-20s LD%. But he's not pitching worse than Pelfrey and Mike doesn't deserve a roster spot over Vance, particularly if he figures it out in Rochester. If Hendriks was healthy, I'd be all in favor of kicking Pelfrey to the curb and giving Liam the rest of the season to prove his mettle.
