Friday night's scheduled contest between the Oakland A's and Baltimore Orioles at Camden Yards has been postponed due to rain. The game will be made up as part of a split-admission doubleheader on Saturday. The first game will be played at 10:05 AM, the second game at 4:05 PM.
While both clubs will be entitled to call up a 26th player, that player can only be used in the second game because the game was rescheduled for tomorrow instead of Sunday. The A's do not have their next off day until Thursday, so they will need a sixth starter for the six games they will play in five days.
MLB.com's Jane Lee tweets that the A's will start Friday's scheduled starter, Rich Hill, in the first game on Saturday, and Jesse Hahn in the nightcap.
Eric Surkamp is the only starting pitcher on the 40-man roster on a regular assignment with Triple-A Nashville, and he would be on turn for for Monday's opener against the Boston Red Sox. It would mean the A's would send two left-handers to the mound at Fenway Park, however. The A's also would not be able to recall whoever they demoted to the minor leagues for 10 days.
One shall we say speculative alternative would be to simply end Henderson Alvarez's rehab early and have the ground ball pitcher go 90 pitches or six innings on Tuesday or Wednesday at Fenway Park. The A's could demote Kendall Graveman or Sean Manaea after his start, which still appears to be lined up for Sunday and Tuesday, respectively.
