The Nationals' series opener against the Orioles has been postponed due to rain. It will be made up at 4:05 p.m. Thursday.
The two clubs were set to open the second half of their annual Battle of the Beltways interleague series, but a steady rain began falling at Nationals Park around 4:30 p.m. and wasn't expected to let up until much later in the evening.
Thursday was a common off-day for both clubs, making it an obvious choice for the makeup game. Traffic, though, could be an issue with the Pope wrapping up his visit to the District. It also required approval from the players' association, because it leaves the Nationals with 24 consecutive scheduled game days, four more than the maximum allowed.
"It is what it is," manager Matt Williams said. "We've got to play, and play well and win baseball games. So we'll hopefully start that again tomorrow."
Both the Nationals and Orioles will push back Monday's scheduled starters (Gio Gonzalez and Ubaldo Jimenez) to pitch Tuesday night. The Orioles announced the rest of their rotation will remain in order, with Chris Tillman on Wednesday and Tyler Wilson on Thursday.
The Nationals, meanwhile, may decide to alter their rotation after Gonzalez starts Tuesday, potentially choosing to skip Tanner Roark's spot and go straight to Max Scherzer and Jordan Zimmermann on normal rest.
"Given the rainout, we can look at some things. We're in the process of doing that. But as far as tomorrow, it'll be Gio."
"Given tonight's cancellation, we can set it up," Williams said. "Depending on everybody's health, of course, and how everybody's feeling and their off-days and regular rest and all of that. We'll do that tonight and have more information for you tomorrow on that."
