The Diamondbacks said after Friday’s game that Brandon Webb would be shut down for three weeks after his latest shoulder setback. Arizona is still maintaining that no MRIs have revealed any structural damage, but this seems like a big step to take if that truly was the case. That Webb will go three weeks without throwing suggests that it will be six weeks before he’s back starting for the Diamondbacks, even if there are no additional problems. Yusmeiro Petit should have some value in NL-only leagues in the meantime. Manager Bob Melvin announced the decision after the Diamondbacks lost to San Francisco 5-1 on Friday night. “He won’t do anything for a week and then he’ll do some strengthening for two weeks, no throwing,” Melvin said, “and then we’ll see where we are after that.” Webb’s bullpen session was canceled Friday when the right-hander felt tightness in the shoulder while playing catch. It was supposed to be his second bullpen workout. He felt fine after his first, 33-pitch session on Tuesday. The plan had been for Webb to throw to hitters if Friday’s bullpen went well, then perhaps have him make a minor league start. An MRI showed a small amount of fluid in the shoulder but no structural damage. Webb went on the 15-day disabled list April 13, retroactive to April 7. Right-hander Yusmeiro Petit — 0-1, 6.00 ERA in three appearances, two starts — will continue to take Webb’s place in the rotation.
The 2006 NL Cy Young Award winner, who was 22-7 last season, was rocked for six runs in his April 6 start, getting a no-decision in a 9-8 victory over Colorado. He was scrubbed from his next start, then the decision was made to put him on the DL. It’s just his second trip to the disabled list in his seven major league seasons. The other was in 2003. Webb has pitched more than 200 innings in each of his last five seasons. “He’s a guy we’re going to be careful with,” Melvin said before the game. “We’re not going to push him and say ‘See if you can throw through it and see if it loosens up.’ He’s too important for us to try to push through something through that.” With the way the Diamondbacks are going to baby Webb, we likely won’t see him until late May at the earliest. Keep the must-start Fantasy SP reserved until further notice. (Rotoworld, CBS Sports)
