"No problems with my ankle, and even did some comebackers and covering first out in the outfield. So, it was a good day," Lindstrom said. "[White Sox pitching coach Don] Cooper was even pleasantly surprised.
"He asked me what I wanted to take out of the bullpen session, and I said, 'My mechanics.' I wanted to make sure they are fluid. Obviously, I want to throw strikes. But I think it was even better than expected. It was nice.
"It's going to take another couple of weeks to probably allow my ankle to continue to heal from all the workouts and stuff I've been doing. I'm encouraged."
