Bits: Edinson Volquez a buy-low option

&#8226 Cincinnati Reds right-hander Edinson Volquez returned from his minor league stint and allowed only one run in seven strong innings Tuesday. Volquez fanned five and walked two. Through 10 starts, his problems were walks and first-inning runs. If he's overcome them, check his 2008 numbers for upside and add now.

&#8226 Los Angeles Dodgers rookies Dee Gordon and Rubby De La Rosa had successful starting debuts Tuesday in Philadelphia. Gordon, weighing roughly 150 pounds, had three singles, stole a base and scored a run leading off at shortstop. He certainly can run. De La Rosa was wild; he walked five in five innings and threw more balls than strikes, but he won. Neither is ready for standard leagues yet, but Gordon is closer.

&#8226 Speaking of shortstops, Boston Red Sox veteran Marco Scutaro came off the DL Tuesday and singled in four at-bats. Scutaro should play with Jed Lowrie, owned in 80.7 percent of ESPN standard leagues, needing a shoulder MRI and likely to miss time. Don't bother owning Scutaro, but if Lowrie hits the DL, move on from him as well.

&#8226 More confusion in the Dodgers' bullpen: Right-hander Vicente Padilla has a bulging disk in his neck and is out indefinitely. So who closes? Well, right-hander Matt Guerrier was summoned Tuesday in Philly ... for the seventh inning with a 4-1 lead. It looks like rookie Javy Guerra, who pitched the ninth inning up 6-2, is the choice.

&#8226 The Oakland Athletics revealed two new infield starters Tuesday, as rookie Jemile Weeks led off and went hitless in four at-bats playing second base, and former Detroit Tigers castaway Scott Sizemore singled in three at-bats at third base, batting eighth. Personally, I like Sizemore. He has double-digit power and speed, and he'll soon be eligible at second base and third. Weeks can run but has no power and could be overwhelmed.
