Notes and updates before tonight's game

Pitcher Jake Arrieta hadn't arrived at Camden Yards when reporters met with manager Buck Showalter shortly after 4 p.m., but he's on the field now for batting practice and will be available in the bullpen. "It's his day to pitch," Showalter said. "We needed some length out there and Jake fit for us. We'll see what the next couple days bring. Freddy (Garcia) would also be available to us in the 'pen tonight. He was available last night, too, in his words." Arrieta is "an option" to start if Miguel Gonzalez goes on paternity leave within the next few days, Showalter said. The same is true of Zach Britton, T.J. McFarland and Kevin Gausman, who was optioned after last night's game. The Orioles received confirmation last night that Gausman would be eligible to return in fewer than 10 days if he's replacing a player on paternity leave. "We're kind of in the mode of, let's see what tonight brings and smoke clears and see what presents itself," Showalter said. "I know they have a doubleheader today in Norfolk." Showalter didn't make any promises to Gausman. He could be back quickly, he could stay in Norfolk all season - though the latter scenario seems highly unlikely. The Orioles want Gausman to go down there, at a level he's never pitched at, and earn another promotion. They also don't want the other starters to feel as though Gausman is ahead of them. "If we had played nine innings, Gaus would have stayed," Showalter said. "I told him that last night, probably a little too up front about it. But I also told him there were no assurances. The good side of it is, he leaves with a good outing and it gives him a chance to take a deep breath and kind of think about some things. "See what the needs are going to be here. I told him to go down there and present himself as an option for us. It's all in his hands. We have other people that we like, too, and that's good to know. That's a good feeling. He could go down there and pitch well and present himself as a good option and still not (return). That's kind of the way it works." Pitching coach Rick Adair talked to Norfolk pitching coach Mike Griffin today about "some things we want to fine-tune a little bit and some areas of emphasis," Showalter said. "And Gaus knows." This isn't just a paper move. Gausman will report to the Tides "and settle in there," Showalter said, "unless somehow a situation presents itself that he would be needed to come back before the 10 days or after 10 days." Showalter said Wei-Yin Chen still has "a lot of hurdles" to clear before he's an option for the Orioles. Pitcher Jason Hammel isn't at the ballpark today. Hammel and his wife, Elissa, picked up a virus from their young son. "He's been pretty ill since 3 o'clock this morning," Showalter said. Hammel's next start is Monday. The Orioles are hoping to avoid pushing him back. "So that's another sidebar to all this moving around," Showalter said. "Hopefully, this will come and go by then." Outfielder Nolan Reimold told reporters yesterday that his injury rehab assignment would begin Tuesday at Double-A Bowie, and nothing changed after he ran sprints. He's still reporting to the Baysox. Alexi Casilla took batting practice and is available to hit and play second base tonight. Brian Roberts also took BP outdoors. Manny Machado is just the fourth player since 1969 to have two hitting streaks of 11 or more games before turning 21, according to STATS. He joins Ken Griffey Jr., Robin Yount and Mike Trout. According to MLB, the last time that the Orioles played 13 or more innings without issuing a walk before last night was April. 21, 1983, when they beat the Rangers 3-2 in 14 innings. Jim Palmer started that game. Single-A Frederick catcher Zane Chavez, recently named to the Carolina League All-Star team, was placed on the disabled list today with a strained oblique.
