There are still playoff races to be decided and they get closer by the day. All times Eastern.
1 p.m., MASN, NESN: Orioles at Red Sox. This is the first game of a split doubleheader, the makeup of a rainout on May 17. The Red Sox are starting Kyle Weiland and John Lackey. The AL wild card race could be real interesting by the end of the day. Game 2 is at 7 p.m. ET.
7 p.m., MLB Network, CSN Philadelpha, FSN Midwest: Cardinals at Phillies. What, you again? The two teams finish up their "wraparound" series with St. Louis just 3-1/2 games out of the wild card lead. Some MLBN viewers will see game 2 of the Orioles/Red Sox doubleheader.
7 p.m., SportSouth, FSN Florida: Braves at Marlins. Atlanta is 40-35 on the road. Florida is 28-44 at home. The Braves need to keep winning to stay ahead of the Cardinals... and also the Giants, who are just four games behind them.
