Davis to miss two games on paternity list

BALTIMORE -- With his wife about to have their first child, Chris Davis left the team on Sunday and was placed on the paternity list.

Orioles manager Buck Showalter said that if everything works out, the first baseman could rejoin the team on Tuesday in Milwaukee. Davis' wife could be induced on Sunday to have the baby.

"If everything goes according to plan, he's going to take two of the three days [he's allowed for paternity leave]," Showalter said Sunday. "If there's no complications."

Davis is hitting .260 with seven homers and 25 RBIs in 35 games. He's been hot this week, hitting four homers -- three of which came last Tuesday.

Machado returns to lineup in series finale

BALTIMORE -- Third baseman Manny Machado was back in the starting lineup on Sunday, but the Orioles waited until after he took batting practice and ran before putting him in there.

Machado didn't play Friday or Saturday after coming out of Thursday's game with stiffness in his right groin, and manager Buck Showalter said before batting practice on Sunday that he had two lineups ready -- one with Machado and one without.

But Machado played and batted in his usual No. 2 spot. He homered to lead off the fifth and finished 1-for-2 with a pair of walks, an RBI and a run scored.

That's a break for the injury-riddled Orioles, as first baseman Chris Davis missed Sunday's game, and likely Monday, on paternity leave, and catcher Matt Wieters already is on the disabled list.

Showalter said he tested Machado a bit on Saturday. The skipper made a bunch of moves late in the 9-0 loss to the Indians, one of which involved losing the DH, so he told Machado he could be pinch-hitting to see how he reacted.

"Batting gloves went on, got that look on his face, pine-tarred the bat up," Showalter said. "I wanted to get that juice flowing."

With Hundley on board, O's to carry three catchers

BALTIMORE -- Catcher Nick Hundley, acquired from the Padres on Saturday, joined the team on Sunday morning, and the Orioles have decided to carry three catchers for now. Caleb Joseph got the start in the series finale against the Indians on Sunday.

Manager Buck Showalter said that he wants Hundley to take it easy for a day after just getting to Baltimore Sunday morning.

"I talked to Nick this morning," Showalter said. "He's been on [the] red-eye all night, a lot of things moving around. There's been a lot going on in his life. Packed up his life and flew across the country on a red-eye and just got here."

Showalter said he wants to let everything slow down a bit for the 30-year old Hundley, allowing him to take everything in and adjust to his new team.

With Manny Machado back in the lineup Sunday, the Orioles made a few other moves. They optioned Steve Lombardozzi to Triple-A Norfolk and recalled pitcher Preston Guilmet from Norfolk. Chris Davis was placed on paternity leave.

Worth noting

Nelson Cruz now has 44 homers and 124 RBIs in his last 162 games, going back to Sept. 27, 2012. He's been the Orioles' top power hitter so far this season.

Nick Markakis keeps hitting early. Entering Sunday, he was batting .435 (20-for-46) in the first inning of games this year. Twenty of the 59 hits he's gotten this year have come in that inning.

Adam Jones now has a .477 average against left-handed pitchers, tops in the American League.
