Orioles second baseman Brian Roberts sat out Wednesday game's, but he's not concerned by back spasms. He said he would play through the spasms if it were the regular season. The injury came up when he dove into first base during a game against the Yankees on Monday night. "I never really said anything because I wanted to keep playing," Roberts said. "When I get them, they usually come on and then they go away on their own after a couple days. I probably didn't help things by sliding when I already had back spasms, but that wasn't the cause of them."
