Atlanta -- Jeff Karstens began an eight-inning relief effort in a game he was originally scheduled to start Wednesday and Pittsburgh scratched out a 3-2 win over Atlanta.
Karstens was replaced as the starting pitcher by Charlie Morton, who was called up from Class AAA Indianapolis to face his former team.
Morton, however, suffered tightness in his right hamstring after one inning and was replaced by Karstens (3-4), who gave up a run on four hits over 4 2/3 innings.
Three more relievers combined to allow a hit over the last 3 1/3, with Matt Capps getting his 14th save despite giving up a solo homer to Garret Anderson in the ninth.
