"My arm feels great," said Lindstrom, who last pitched in a game on Wednesday. "I'm just working on my stuff, all three pitches. I look forward to getting back on the mound and getting myself ready for the season."
Lindstrom isn't sure exactly what caused the back spasms, but he thinks his bed -- which he has replaced -- was a contributor. The right-hander played catch on Sunday and has been getting treatment to help calm things down. Assuming Lindstrom comes in Tuesday feeling OK, he will be eligible to get back into games immediately. Pitching coach Rick Adair said Lindstrom could throw Tuesday or Wednesday.
Acquired in an offseason trade with Colorado, Lindstrom is expected to be one of the Orioles' late-inning arms in the bullpen.
