White Sox activate Matt Lindstrom

The Chicago White Sox reinstated reliever Matt Lindstrom from the 15-day disabled list in advance of Tuesday night's game at San Francisco.

The right-hander had been on the disabled list since May 20 due to an ankle injury he suffered the day before an outing at Kansas City. He underwent surgery on May 23.

He opened the season as the White Sox's closer, going 2-1 with a 3.32 ERA and six saves in nine opportunities. The White Sox first went to Ronald Belisario at closer in replace of Lindstrom, before moving to closer-by-committee. Jake Petricka has been handling the role of late.

Lindstrom struggled early in the season, but at the time of his injury he had converted his last five save opportunities, while eight of his last nine appearances had been scoreless.

He takes the roster spot of left-hander Eric Surkamp, who was optioned back to Triple-A Charlotte after Sunday's game at Seattle.
