Jorge Posada will be honored at Yankee Stadium when the team retires the former catcher's No. 20 and gives him a plaque in Monument Park during ceremonies before New York plays Cleveland. On Sunday, longtime ace Andy Pettitte gets the same star tribute when the Yankees retire his No. 46.
Randy Wolf is set to see his first big league action since June 14, 2014, when the 38-year-old starts for Detroit against Texas.
The Cubs' Dan Haren is ready to make his start after being hit in his ankle by a line drive in his last start. He's had success in the past against the Braves, going 6-2 with a 3.25 ERA.
Mike Leake comes off the disabled list to make his second start for the Giants since being acquired before the July 31 non-waiver trade deadline. He allowed two runs in 6 1-3 innings in his first start for the Giants on Aug. 2. Pittsburgh's Gerrit Cole starts against a favorite foe. He's 3-0 in three outings against San Francisco.
