Orioles pre-game: Roberts, Hall, big days in Frederick and Bowie

It seems a little weird here this afternoon at Camden Yards for today's 4:05 p.m. game against the Royals.

No batting practice for the Orioles today. The Royals spent pre-stretch time throwing a football around in front of the visiting dugout.

Orioles left-hander Wei-Yin Chen hopes to build on Jason Hammel's six shutout innings last night. He will be opposed by Royals right-hander Felipe Paulino, who threw seven scoreless innings against the Orioles at Kauffman Stadium on May 16. He allowed just five hits and struck out nine with two walks on that afternoon, dominating the Orioles before they rallied for a 4-3, 15-inning win.

Brian Roberts has a day off from his rehab assignment. He was just seen doing running drills in right field. He's scheduled to return to Double-A Bowie for games there Sunday and Monday. He is slated to play at Low-A Delmarva on Tuesday and Wednesday, and Orioles manager Buck Showalter said he'd like for Roberts to finish his rehab assignment -- which has to end by June 11 -- at Triple-A Norfolk. That would also allow Roberts the chance to play on the road, something he has yet to do.

Showalter said the goal is for Roberts to get about 50 plate appearances, the equivalent of a spring training.

Also, Bill Hall cleared waivers and was outrighted to Norfolk.

It's a big day throughout the organization. Top pitching prospect Dylan Bundy is making his first start at High-A Frederick after dominating the South Atlantic League. Also, there will be several major leaguers playing at Bowie today -- even without Roberts. Endy Chavez will be leading off and playing in left, Mark Reynolds is hitting third and playing third and left-hander Zach Britton will making his first minor league rehab start.
