Morse excited to join Orioles' playoff chase

NEW YORK -- New Oriole Michael Morse, who arrived at the team hotel in New York at 3:30 a.m. ET on Saturday, stood in the visiting clubhouse at Yankee Stadium and talked about how excited he was to be part of a contending club.

"I look at it as, 'I turn the page of what was going on over there,'" said Morse, acquired in a waiver-claim deal Friday from Seattle, "and I get to start fresh here and help this team get to the playoffs."

Morse, who is coming off a strained quadriceps injury, posted a disappointing .226//283/.410 line in just 76 games with the Mariners and said he's fully recovered from that and an earlier broken finger.

"He's pretty excited about being here," manager Buck Showalter said of Morse, who is expected to start Sunday against lefty Andy Pettitte. "He was kidding about some of our guys. When they were in our place, he had heard a lot of talk about our interest in him. He said it's been a long wait."

Morse spent the previous four years in Washington, and hit .302 with six homers in the last month of 2012's regular season before going 5-for-19 with a homer in the playoffs.

"This is a great area," he said. "Baltimore-DC area is a great area. It's a good baseball area. There are a lot of fans. To me, it's always been good. I'm just happy to be back."

Morse, who will have the ever-popular "Take On Me" as his at-bat song, came up with center fielder Adam Jones in Seattle and knew a handful of other Orioles, which makes the transition a little easier. And then, of course, there is the O's hitter-friendly Camden Yards ballpark.

"I am [excited to hit at Camden], but I'm also excited to watch these guys and keep watching how they're playing," he said. "It's all about getting to the postseason. That's the goal. Whatever it takes, I'm for it."

Nagging wrist injury sends Pearce to DL

NEW YORK -- Steve Pearce's nagging left wrist injury continues to be an issue, and the O's decided to place the outfielder/designated hitter on the 15-day disabled list for the second time this season prior to Saturday's game.

"It's been very frustrating," said Pearce, who missed more than a month with wrist tendinitis earlier this season. "I've been dealing with it all year, and when I started getting into a groove, it started to flare up again. It's probably something I'm going to have to address in the future."

Pearce's roster spot was taken by new Oriole Michael Morse, and the plan is for Pearce to go to the team's spring facility in Sarasota, Fla., and try to work his way back this season. Both Pearce and manager Buck Showalter said Saturday they think he can make a mid-September return.

"Stevie is such a competitor and such a grinder," Showalter said of Pearce, who the skipper stayed away from using the last few days because of the wrist. "He's a physical guy, and not to be carrying everything. ... He's gone through periods when he feels great, and then because of the work that all guys do to get ready to play, it's just a very repetitious sport, and there's a fine line between it.

"But we're going to take a look at it with our specialist down there and make sure there's nothing structurally wrong, which we don't think there is. I think he'll be back in 12 days. I hope."

Pearce, who had his left wrist wrapped while talking to the media Saturday, said it's more inflammation than anything else and a lighter pregame load didn't really help. In 38 games for the Orioles this season, Pearce has a .241/.328/.361 line.
