Manager Buck Showalter said the Orioles will run out right-hander Yovani Gallardo and left-hander Wade Miley to start Friday and Saturday against the Arizona Diamondbacks, but alluded to some lingering physical problems for those in the rotation that will dictate how the rest of the season shakes out.
The Orioles have their final day off on Monday, which Showalter will use to set the rotation after the weekend.
"We have some moving parts with our rotation, some health things we've got to be on top of. We'll wait and see how Miley's work day goes," Showalter said. "We'll wait and see how [Kevin Gausman] feels after his start, how [Chris] Tillman feels after his start. We've got to gauge it, but we have more than five [starters] and we have off-days."
Tillman starts the Orioles' series finale Thursday against the Boston Red Sox, his third start since being limited for nearly a month with shoulder bursitis, while Miley's start Saturday will come after he left his start Sunday with a mild upper back strain following four scoreless innings.
Gallardo, meanwhile, will be pitching on seven days' rest, with his most recent start coming on Sept. 15. That start, in which he allowed six runs in 3 1/3 innings, came with eight days off between outings. Showalter said this layoff isn't too long.
"This time of year, I think everybody kind of benefits but you can have too many [days], too," Showalter said. "But these guys know when they're pitching. They do things between starts to make sure."
As currently constituted, right-hander Dylan Bundy, who started Monday, will get an extra day between starts if he slots back into the rotation Sunday. Gausman would be on normal rest Sunday, but could be pushed back until after the day off.
Whoever the Orioles tap to start Tuesday in Toronto could come back for the final game of the season on Oct. 2 in New York. Showalter said they'd not likely have anyone pitch on short rest down the stretch.
"Would I consider it?" Showalter said. "Yeah, I'd consider it. Would I do it? Probably not. We're more likely to give a guy an extra day. We don't really have anybody who would fit in that mode."
On that subject of extra days, Showalter alluded to physical problems his pitchers are dealing with that haven't, and might not become public.
"We've got some things we can play with after the off-day," Showalter said. "But right now, it's about tonight's game. We can see where we are after that. We take in a lot of information each day. We got two or three pieces of information yesterday that play into our decision going forward. There's a lot of things — it seems like over half the stuff never gets public, but you have to kind of keep it in house. It doesn't behoove anybody talking about it publicly."
