Central showdown: Detroit took round one of the three-game series between the Tigers and Indians, giving the home team a one-game lead in the division. Tonight, the Indians have their top starter on the mound, but he's been anything but an ace of late, going 0-5 with an 8.49 ERA in his last six starts. Meanwhile, Detroit's Brad Penny is 3-0 in four starts against the AL Central this season, but he hasn't faced Cleveland. Penny has just one win in his last four starts.

Matchup of the night: The first game of today's day-night doubleheader in Philly was a bit of a laugher following the Phillies' six-run third en route to an 8-1 victory, but the nightcap shouldn't be a repeat with the pitching matchup of Roy Halladay vs. Anibal Sanchez. Halladay, well, is one of the game's premier pitchers, coming into the game 9-3 with a 2.39 ERA. Sanchez is having a good season so far, going 6-1 with a 3.06 ERA and for all of Florida's struggles, the Marlins have won eight of his 13 starts. Marlins at Phillies, 7:05 p.m. ET (Follow live here)
Streaking the other way: The Brewers' losses to the Cubs in the first two games of the teams' four-game series marked Milwaukee's first losses in consecutive games since it's seven-game losing streak from April 30-May 6, a streak of 35 games without back-to-back losses. They'll have to beat Carlos Zambrano, who beat the Brewers on April 8 and is 13-8 with a 3.73 ERA in 32 games against Milwaukee. Chris Narveson (3-4, 4.32 ERA) is on the mound for the Brewers.
