If you live anywhere near Baltimore and have looked out the window today, this doesn't come as a surprise.
Tonight’s game between the #Orioles and Yankees has been postponed due to rain. A make-up date will be announced as soon as possible.
— Baltimore Orioles (@Orioles) August 12, 2014The game will be made up at 1 p.m. on Friday, September 12th as part of a split doubleheader.
This will not affect tomorrow's pitching matchup, scheduled to be Chris Tillman vs. Michael Pineda. Tonight's scheduled starter, Wei-Yin Chen, will pitch Friday night in Cleveland.
Tickets for tonight's game can be used for the 1 p.m. game on September 12th or may be exchanged for tickets to any other game this season on a "dollar-to-dollar" basis, which means that if it's traded for a higher price tier you'll have to pay the difference.
