Troy Tulowitzki needs surgery

The Colorado Rockies announced Wednesday that their star shortstop will have arthroscopic surgery to clean up scar tissue on a nerve in his left groin Thursday. There's no timetable for his return, but Troy Renck suggests it's probable that he'll be out until August.

Tulo's fantasy owners are no doubt bummed, but it could have been worse; a sports hernia - which the team and Tulowitzki feared was his ailment - could have kept him out longer. You'll have to bite the bullet and stash him in all formats.

The extended absence for Tulo gives Chris Nelson extra traction in deep mixed leagues with extra infield spots. Scutaro, who is hitting .344 in 64 at-bats this month, was already a lineup fixture before Tulowitzki went down. Scutaro's long-term value gives him the edge over Nelson.

The Washington Nationals are moving Chien-Ming Wang to the bullpen after he surrendered five earned runs on seven hits in only 3 1/3 innings in his loss to the Tampa Bay Rays Tuesday. Wang had just one strikeout and three walks. In his four starts, he posted a 6.62 ERA and 14 walks against 11 K's in 17 2/3 frames.

A strained left hamstring in spring training delayed Wang's season debut until May 25, when he pitched three innings of relief. Detwiler's solid performance in the rotation (3.88 ERA, 1.27 WHIP) led them to delay Wang's return to the team.

Upon his return, though, the Taiwanese sinkerballer labored, and The Washington Times' Amanda Comak discusses how Wang's delivery and mechanics were out of whack. Wang had plenty of time to get healthy during his rehab assignment, so health shouldn't be a factor. Normally a control-based hurler, Wang's 6.10 BB/9 is directly related to his mechanical issues. He pitches to contact and won't offer you any value pitching out of the 'pen.

Detwiler, 26, retired 11 of the 12 hitters he faced in relief of Wang Tuesday, and he's given up only two tallies in 13 1/3 innings with 10 punchouts since being moved to the bullpen. He's probably at his peak in terms of dominance, but his improved control is a reason to remain optimistic.

There's no guarantee Wang, to whom the club is committed financially, won't return to the rotation at some point down the road if he fixes his mechanics, but Detwiler can still be useful in deep formats. Plus, there's still a realistic chance the Nats shut down Stephen Strasburg depending on their postseason status, which could allow both to be in the rotation down the road.
