LAKELAND, Fla. -- Casey Crosby came to camp with plans to be stretched out as the insurance starter at Triple-A Toledo, but his spring work is on hold for at least a couple of days because of an infection in his left foot.

Crosby was scheduled to pitch in relief in Saturday's split-squad game against the Pirates but was scratched after he had trouble throwing. The infection is on the back foot of his delivery, creating a mechanical problem.

"I couldn't even push off today," Crosby said.

Crosby doesn't expect the issue to last long, but he also doesn't want to try to pitch through it and hurt something else while trying to compensate.
