The Baltimore Orioles and the Philadelphia Phillies have postponed their baseball games scheduled for Wednesday night.

The Pittsburgh Pirates and Orioles were rained out Wednesday for the second straight day,

A single-admission doubleheader was scheduled for Thursday starting at 4:05 p.m. Both teams originally had scheduled to be off Thursday.

Pittsburgh and Baltimore haven't played since Sunday. The Pirates played 20 games in 20 days through Sunday.

The rainouts are delaying the season debut of third baseman Manny Machado, who injured a left knee ligament on Sept. 23 and had surgery Oct. 14. He will come off the 15-day disabled list when the Orioles next play.

Baltimore will have to make a roster move to free a spot for first baseman Steve Pearce, signed to a major league contract Tuesday.

Pearce was designated for assignment on April 22 and released five days later. The Orioles brought him back after first baseman Chris Davis was put on the disabled list with a strained left oblique.

Wednesday night's game between the Phillies and New York was also postponed. The game has been rescheduled for June 2 at 7:05 p.m. Both teams had a day off then.

The Mets beat the Phillies 6-1 Tuesday night in a game played during steady rain after a delay of 1 hour, 28 minutes at the start.

The Phillies have another day off Thursday before opening a three-game series against Washington on Friday. The Mets will travel to Colorado to open a four-game set on Thursday night.
