The groin issue that hampered Javy Guerra in his one inning of a Minor League game Sunday, however, will "slow him down a bit, that's for sure," Mattingly said. Guerra, in his return from a week off because of World Baseball Classic issues, has downplayed the injury, which he didn't reveal until after his Sunday outing.
"He's telling me he feels good," said Mattingly. "We're going to be cautious. I don't think it will be for an extended time, but we'll be cautious for a day."
Carl Crawford continued to take batting practice with the team and said his surgically repaired elbow continues to feel good. Crawford still hasn't resumed throwing since being shut down nearly two weeks ago.
Chris Withrow, out all spring with lower back issues, is getting close to being ready for game action, having thrown several times in the bullpen. Scott Elbert continues his throwing program after two elbow operations.
Relievers Brandon League, Kenley Jansen and J.P. Howell will throw two innings each in a Minor League game on Tuesday.
