Right-hander Aaron Harang's season is over for the Cincinnati Reds, as the team announced he underwent an emergency appendectomy Saturday night.Harang, 31, went 6-14 despite a not-as-awful 4.21 ERA, thanks to the third-worst run support in the National League. He leads the NL in losses and hits allowed (186 in 162 1/3 innings). He won just one of his final 16 starts, going 1-10 with a 4.78 ERA
To fill the roster spot, third baseman Scott Rolen was activated from the disabled list.
Rolen, acquired from Toronto in late July, had been out because of a concussions suffered Aug. 2 when he was hit in the head by a pitch from Colorado's Jason Marquis. Rolen played in two Triple-A rehabilitation games, going 2-for-6 with an RBI.
