Cubs manager Mike Quade isn't worried about drop in velocity. The lack of zip on his fastball has been brought to light more recently, but Marmol's velocity has been down all year, as Fangraphs.com shows his average velocity at 91.8 mph, down from 94.1 last season. ''I just think he's mechanically so unorthodox, so tough to keep in line, that to me is probably as much of it as anything,'' Quade said. ''We'll keep a close eye on Marmol, as we do with all of them... It's an ongoing thing with Marm. He's had a wonderful run here, and this is the first real adversity I think that he's had in his career. But you deal with it, and the rest part of it we'll keep an eye on.''
