-- Baltimore Orioles second baseman Brian Roberts traveled to Baltimore to have his strained right rotator cuff examined by team orthopedist Charles Silberstein. The team should know more about the severity of the injury after Friday's MRI exam.

"The fact if it doesn't improve I wanted to make sure we weren't missing anything," Orioles trainer Richie Bancells said. "When it was apparent he wasn't playing [Thursday] and, in my mind, the next couple of days, it was the best thing to do."

Roberts first complained of discomfort in the shoulder on Wednesday and was scratched from the lineup that night. He isn't sure how he hurt the shoulder, but awoke in pain on Wednesday. A disappointed Roberts declined to speak with reporters.

"There's really nothing else left to say," Roberts said.

Bancells said nothing should be interpreted from Roberts's demeanor.

"That's a natural reaction from a competitor," Bancells said.

Delmarva Pitcher Smith Cut

The Orioles released Class A Delmarva pitcher Chris Smith, who was the seventh overall pick in 2001. Smith was 1-1 with an 8.54 ERA at Delmarva and had battled injuries for most of his career. . . .

Outfielder Tim Raines Jr., who was designated for assignment on Saturday, cleared waivers and was outrighted to Class AAA Ottawa.

Outfielder Luis Matos will see the team's hand specialist today to determine when he can start baseball activities.
