Right-hander Yovani Gallardo, at least for the time being, is the odd man out as the team works to accommodate six starting pitchers upon the return of injured right-hander Chris Tillman on Sunday.
Wade Miley will pitch the series opener Monday against the Boston Red Sox at Fenway Park on seven days' rest after his most recent turn through the rotation was moved back to accommodate the regular schedules of Kevin Gausman and Ubaldo Jimenez around Thursday's day off.
After Miley, right-hander Dylan Bundy and Gausman will stay on turn for the final two games against the Red Sox, and Gallardo will start on Sept. 15 against the Tampa Bay Rays at Camden Yards.
"He'll pitch the next day, depending on how Chris feels, if everything goes well with Chris tomorrow," manager Buck Showalter said. "Everything is kind of a moving part. Especially if Chris gets back, we'll have six to pick from."
Gallardo's most recent start was Sept. 6, when he allowed two runs (one earned) on five hits in five innings to earn a win over those same Rays.
This season, Gallardo has allowed eight runs in 10 innings over two starts against the Red Sox, while holding the Rays to seven earned runs in 15 1/3 innings over three starts. He also fared poorly in his one start at Fenway Park this season.
How the rotation shakes out after Gallardo is unclear, though Jimenez and Tillman could come back and pitch Friday and Saturday on one extra day of rest, provided Tillman comes through his start Sunday without a problem.
Showalter said that will be the key to everything, with Tillman's health more important than anything else coming out of Sunday's game.
"I expect him to be a little rusty," Showalter said. "I think there's a lot of unknown there. He's had not near as much time off as it seems like he's had. But more than anything, we'd just like him to be healthy, because even if he has a little rusty start, each one of them will get better. It's exciting for his teammates to get him back, and for me. But we'll see. We've had some other guys pitch well in his absence."
Davis down on his hand: First baseman Chris Davis, who has spent the entire season dealing with soreness in the thumb area on his left hand, said the two days off he got last week didn't do much to get any of the discomfort out.
"Swinging a bat is painful," Davis said. "I went 0-for-3 [Friday] night. I had two days off before that. I don't think it made a whole lot of difference."
Davis returned Friday after leaving the Orioles' win Tuesday in St. Petersburg, Fla., and missing Wednesday's game. Showalter said he expected Davis would be dealing with the ailment for the rest of the year. Davis echoed that Saturday.
"I couldn't tell you if it was one specific event or if it was something I've been dealing with all season," Davis said. "I obviously haven't been myself all season, but that's part of it. Unfortunately, we have bodies that aren't invincible. When you play a physical game every day for months at a time, you're going to get nicks and bruises. You move on and you go on."
Davis entered Saturday batting .227 with 35 home runs and 78 RBIs.
Around the horn: Reliever Darren O'Day (right rotator cuff strain) will have another bullpen session, likely Sunday, before throwing a simulated game Tuesday in Boston, Showalter said. … Sunday is scheduled to be left-hander Jayson Aquino's final day with the team, as he'll head to Sarasota, Fla., to join the team's taxi squad.
