Teahen, who aggravated a right oblique muscle strain during a May 11 game against the Angels, returned after an eight-game rehab assignment with Triple-A Charlotte. He went 6-for-31 in his time with the Knights, playing mostly third base, but also seeing action at first base and one game each in right and left field.
"I kind of worked my way through it," Teahen said. "But now I've played eight days in a row or whatever it was and [the oblique] held up good and got looser as I went, so it's good. I'm ready to go."
Ten of Teahen's 11 starts before his injury came at third base, but he also saw action at first base, left field and right field, which manager Ozzie Guillen said will help when he's trying to get rest days for some of his regulars.
"Now's the time it's starting to get hot, and now we can get a break a little bit to Carlos [Quentin] and [Adam] Dunn and [Paul Konerko]," Guillen said. "And having [Teahen] here, gives me an opportunity to play [Brent] Lillibridge in center field and have [Alex] Rios out, and have more activity in the lineup."
Reliever Jeff Marquez, who didn't make any appearances after being called up on May 30, was designated for assignment to make room for Teahen. The three-week stay on the DL was considerably shorter than last year, when Teahen missed more than two months of the season after fracturing his left middle finger in a May 30 game.
"It's aggravating," said Teahen about the missed time. "Last year with the finger, that was totally random, but this year, thankfully, it was only a couple weeks and now I can get back in there and help out."
