Agree on Martin and SWR, not so much Clemens, as mentioned earlier, his month of June skewed his overall numbers. I would also add Funderburk.
Clemens slash from July 1 to the end of the season: 65/78 GP, .217/.269/.412 (.681 OPS, app. 87 OPS+), 10 HR, 26 RBI, 59/16 K/BB, 0.6 fWAR. I wouldn't exactly call that seizing an opportunity.
Funderburk slash from July 1 to the end of the season: 30 GP, 29 IP, 3-1 W/L, 1 SV, 1.86 ERA, 31/14 K/BB, 0 HR, 0.6 fWAR.
