OKLAHOMA CITY -- O's slugger Sammy Sosa was in good spirits before the game, but had to make his own sign to put up over his locker.

"They didn't even have my name up," Sosa said to teammate Miguel Tejada.

So Sosa scrawled his own name on a piece of paper and taped it to the top of the locker.

The new Orioles star is back in Oklahoma City, where he spent time in the Rangers' organization in 1989.

Sosa played for the Oklahoma City 89ers, and before that, played with the Double-A Tulsa Drillers. He hit an inside-the-park home run in his first at-bat in Tulsa.

"I was just trying to make the ballclub back then," Sosa said. "That was great."

Injury update: Third baseman Melvin Mora was hit by a pitch on the right wrist during Wednesday's game in Jupiter, Fla. He did not come with the team to Oklahoma City. X-rays were negative and the Orioles think he will be ready for Opening Day.

Second baseman Brian Roberts is listed as day-to-day after fouling a ball off his right shin Wednesday.

Big crowd: The 11,516 fans on Thursday night at Bricktown Ballpark was the biggest Spring Training crowd the Orioles have played in front of this year.

Their previous high was 8,010 in a game against the Boston Red Sox.

More moves: The Orioles have added five position players for their final four spring games: Bernie Castro, Tripper Johnson, Eugene Kingsale, Woody Cliffords and Nick Markakis.

Happy reunion: Former Cardinals pitcher Steve Kline was on hand Thursday joking and laughing with former manager Tony La Russa.

Kline has a 1.64 ERA in 11 appearances with the Orioles this spring.

Coming up: Bruce Chen will start for the Orioles on Friday night at 7:05 p.m. ET in the finale of the two-game set against the Cardinals in Oklahoma City.
