PITTSBURGH — Former All-Star closer Dan Kolb was added to the Pittsburgh Pirates' roster on Tuesday and utility infielder Don Kelly was designated for assignment.

The right-handed Kolb, signed to a minor-league contract during the offseason, was 2-1 with a 3.15 ERA and four saves in 18 games at Triple-A Indianapolis. Pittsburgh bought Kolb's contract.

Kolb had 21 saves with Milwaukee in 2003 and 39 in 2004, but lost his closer's job after being traded to Atlanta, where he was 3-8 with 11 saves in 2005. He returned to Milwaukee last season and was 2-2 with a 4.84 ERA in 53 games, mostly as a setup reliever.

Kelly, who was born in Butler, surprisingly made the Pirates' opening day roster as a utility infielder. But he played little, hitting .154 (4-for-26) with no extra-base hits.

Kolb gives the Pirates 13 pitchers, including eight relievers. Right-hander Matt Capps, who recently became their closer, is awaiting word on his appeal of a four-game suspension for hitting the Brewers' Prince Fielder with a pitch.
