Mike Stanton, since being called up to the Marlins, is striking out in 42% of his at bats.
John Ely has given up 15 earned runs in his last 15 innings.
Edinson Volquez, a pitcher with whom I have a long and sordid fantasy history, has now pitched eight scoreless innings in a drug-free rehab stint. Tommy John + the residual roids in his system should produce viable results when he's eventually called up in July to replace Mike Leake's corpse.
Carlos Lee's OPS is back over .650.
Results since Hiroki Kuroda's purported mechanics change: 12 IP, 7 H, 0 ER, 3 BB, 14K
You cannot directly add a free agent to your DL. You first have to drop another player to make room on the active roster, then move him to the DL, then pick up some other free agent to refill your roster spot.
