Game of the day: Chicago Cubs at Chicago White Sox, 8:10 p.m. The cross-town rivals have a long way to go to be independently relevant this season, but this is one of the matchups interleague play was designed to feature. Right-hander Carlos Zambrano (5-4) will start for the Cubs, looking to bounce back from two straight subpar starts in which he allowed 12 earned runs over 12 1/3 innings. Right-hander Gavin Floyd (6-6) will start for the White Sox, aiming to maintain stellar numbers in interleague play. Floyd is 5-2 with a 1.71 ERA in 11 career starts against teams from the other league.

Other game to watch:

Houston at Texas, 8:05 p.m . In an in-state matchup, last-place Houston will visit first-place Texas. This is the interleague rivalry that could spur Houston to move to the American League if the proposed realignment plan ever takes shape. Left-hander J.A. Happ (3-8) will start for the Astros, looking for his first win May 14. The former Phillie is 0-4 in his last six starts, all Houston losses. Left-hander Derek Holland (5-2) will pitch for the Rangers, coming off an ugly start in which he allowed six runs on seven hits and five walks in a 12-4 loss to the Yankees on Wednesday.

Chatter: “This was an extremely frustrated, proud man. This kind of caught us a little off guard. I know there’s been a lot of speculation, everything, but this is not something I thought was going to happen today.” – Larry Beinfest, Marlins president of baseball operations, on former Florida manager Edwin Rodriguez, who resigned Sunday morning in the middle of his first full season as manager. Florida extended its losing streak to 10 Sunday afternoon, and it has lost 18 of its last 19 games.
