BRADENTON, Fla. — John Grabow, one of the most reliable pitchers in the Pittsburgh Pirates' bullpen the past three seasons, is hurting.

The left-hander has a sore elbow that has kept him off the mound since working an inning against the Cincinnati Reds last Sunday. The Pirates have no timetable for when he can pitch again.

Grabow made 203 relief appearances from 2004-06, ranking 11th among major-league lefties in that span.

He has not been on the disabled list in his major-league career.
