BALTIMORE -- Brian Roberts continues to be slowed by a rash of medical issues, as the Orioles second baseman has been dealing with flu-like symptoms and stomach discomfort and is expected to undergo an endoscopy on Thursday.
Roberts has been on the disabled list since April 10, exiting the previous day's home opener with a strained abdominal muscle suffered while sliding into second base. The slide is believed to have caused the muscle strain and also reaggravated the herniated disc in his lower back, an injury suffered during offseason workouts in Arizona that limited Roberts until Spring Training's final week.
He saw back specialist Dr. Lee Riley earlier this week and has not been cleared to participate in any baseball-related activities. It's no secret that the Orioles offense has suffered without Roberts in the top spot. The team entered Wednesday's game hitting .244 and has been outscored by opponents 102-67 this season.
"I dare say how would some of these other teams do if they were missing their leadoff hitter," Orioles manager Dave Trembley said. "You have to adjust. I think people try to exploit it and they should exploit it from the other side, and the guys that are now hitting without Roberts in the lineup have to show a lot more patience, have to be willing to take what's given them instead of trying to manufacture and make up for the fact that B-Rob's not in there. I think that's just a basic premise that exists right now."
A dynamic table-setter for the top of the Orioles lineup, Roberts hit .283 with a .356 on-base percentage and a .451 slugging percentage in 159 games last season. The 32-year-old hit 16 homers with 79 RBIs and a franchise-record 56 doubles. The latter number set the all-time single-season mark for two-baggers in a season by a switch-hitter.
