ROY RETURNS: Roy Oswalt's start is being labeled a "rehab start" even though it's in the big leagues and he'll be limited to 60-65 pitches, but the Phillies have to be glad he's back, even in a limited engagement. That said, Roy could've gotten a better draw in his return, facing St. Louis' Jaime Garcia, who may be pitching better than anyone else in the National League. Garcia is 5-0 with a 1.89 ERA. Oswalt left the team after April 26 after tornadoes hit his homes in Mississippi, but when he returned his lower back was still bothering him, so he went on the DL.

WIN NEEDED: The Yankees have lost six games in a row and have created more off-the-field headlines than on-field headlines of late. Jorge Posada, apparently, is sorry both on and off the field for his first month of the season. If you're the Yankees and you've lost six games in a row and are wrapping up a series against the division leaders, who else would you want on the mound other than Ivan Nova (3-3, 4.70 ERA)? Nova gave up eight runs and 10 hits against the Royals in his last start, so he should have no trouble against "Big Game" James Shields (4-1, 2.08) and the Rays, right? Well, Shields is 3-8 with a 4.91 ERA in his career against the Yankees, so there's that. Yankees at Rays, 6:40 p.m. ET (Watch live)
WIN NEEDED II: You think losing six games is bad? Try nine. That's where the Twins' are, losing their last nine games. Oh, and Felix Hernandez is on the mound with an extra day's rest. King Felix hasn't exactly been royal of late, but even at his worst, he's still an imposing figure on the mound. Meanwhile, Francisco Liriano left his last start after just three innings with flu-like symptoms which included trouble breathing and allowing four runs. But he's won his last three games against the Mariners, so there's that.
