Roberts begins increasing baseball activity

WASHINGTON -- Manager Buck Showalter updated the status of several injured players before Tuesday's game against the Nationals.

Backup catcher Taylor Teagarden caught five innings yesterday in extended spring action in Sarasota, Fla. He will be the designated hitter tonight and catch seven innings tomorrow, Showalter said.

"After that, he may go to one of our Minor League clubs, so he's coming along well, so that's encouraging."

Top position player prospect Jonathan Schoop will seek a second opinion on his back in California.

Showalter didn't have much to update on starter Wei-Yin Chen and his strained right oblique. The manager said he's provided occasional updates on Chen's pain level and that he's making progress, "little by little." There are no plans for him to pick up a baseball in extended spring games just yet.

Second baseman Brian Roberts is still on the mend from rupturing a tendon behind his right knee, and won't return for a while, but the manager was encouraged with reports Tuesday.

"Brian did some tee work, increasing his baseball activity," Showalter said. He added that Roberts' return is a matter of "when not if."

Third baseman Wilson Betemit started throwing in Sarasota.

"Hope we're getting four or five guys back at some point soon," Showalter said.

Machado: Hitting success is 'all about routine'

WASHINGTON -- Orioles hitting coach Jim Presley marveled at Manny Machado's mature approach at the plate when he came up last year, and the 20-year-old's offensive surge this season isn't due to any adjustments.

In fact, it's quite the opposite.

"Just keeping that routine going," said Machado, who has had roughly the same approach to hitting since he was 12. "It's all about routine."

Machado is making hitting in the big leagues look routine. Fresh off a three-hit game on Monday, Machado entered Tuesday's game with 75 hits -- tied with Tigers slugger Miguel Cabrera for tops in baseball -- and was hitting .335 with five homers and 28 RBIs in his first full Major League season. Machado's 75 hits in the first two months of the season are the most by any player under 21 since 1921, with Ken Griffey Jr. compiling 66 in 1990. Machado also led the Majors with 48 hits on the road, with teammate Adam Jones second entering Tuesday at 42.

"He's got a pretty good approach about it, doesn't seem to get too high or too low," manager Buck Showalter said of Machado, whom he moved to second in the batting order this season. "Very competitive. You can tell in between at-bats and things, if he doesn't do something he thinks he's capable of doing.

"He's handled his success very well, because there's a lot of people pulling on him now, and rightfully so. It's not going to shorten up. One player was asking me something today about a lot [reporters] around [Machado's] locker, and I said, 'Right, that's good. Usually for the right reasons.' It's like autographs. When you've got to worry is when they quit asking. So Manny's in good shape."

Hunter available out of 'pen following X-ray results

WASHINGTON -- Reliever Tommy Hunter was available out of the bullpen Tuesday, just two days after barehanding a hard-hit ball from Toronto's Jose Bautista.

Hunter had an initial X-ray taken Sunday and a more advanced follow-up X-ray on Monday. Both came back negative.

"They explained it to me: in one I was driving a not-so-cool car, and one of them I was driving a really cool car, they're both going to get you to the ending line, but it's just a matter of what kind of style you're riding in," Hunter said. "I don't know, one's grainy, one's not grainy."

The 26-year-old right-hander played light catch before Monday's game at Nationals Park and said Tuesday he doesn't think he'll have any limitations going forward.

"It's sore, it's kind of like a hitter taking a ball off the ankle. It's not broke, so might as well throw," Hunter said.

In Sunday's outing, Hunter allowed one run on four hits over 1 1/3 innings and worked out of a bases-loaded jam to end the seventh inning to continue his impressive run. Since April 12, Hunter is 3-0 with a 1.07 ERA in 15 outings, striking out 17 and walking five.

Worth noting

• Showalter was joined by about eight or nine Orioles who went to the Walter Reed National Medical Military Center in D.C. on Tuesday. It was an emotional experience for the group, and you can help by participating in the auction on orioles.com. The Orioles' digicamo pattern jerseys from Monday's game were autographed and authenticated, with proceeds from the auction going to the Yellow Ribbon Fund to benefit patients at Walter Reed. The auction runs through midnight ET June 2.

• The Orioles will face Max Scherzer, Justin Verlander and Rick Porcello in this weekend's series versus Detroit.

•  The Orioles were held homerless on Monday after homering 16 times in their previous six games.
