CHICAGO -- Matt Lindstrom threw another successful bullpen session Saturday, covering 30 pitches. The right-hander will throw another bullpen Monday and then throw live batting practice to Avisail Garcia next weekend when the White Sox are in Minneapolis.
If all goes well, a Minor League rehab assignment will follow. Lindstrom has been out of action since May 20, having had surgery on his left ankle that he injured while pitching May 19.
"We're going to do a rehab assignment for sure to simulate that game speed," Lindstrom said. "There really is no way to do that other than in a game. I've done some rehab assignments before in my career, so I know what to expect. Just hopefully I don't have to do three or four. Maybe one or two will be good."
Manager Robin Ventura postponed the decision as to whether Lindstrom would resume his closer duties upon return. Zach Putnam and Jake Petricka are handling that role, with Lindstrom just trying to get back into action.
"I'm so eager to get back with the club," Lindstrom said. "I see we are playing pretty good ball since the break started. I don't know, it's been a long time. It seems like I have been away longer than two months. For me, I just want to play, so that's the main thing."
