It's hard to say, but I'm starting to believe he might be done. Right now, Konerko can't catch up to fastballs right down the middle. He used to be one of the best fastball hitters in baseball. Last night you could see him get really mad after making an out on a fastball he used to be able to crush in his sleep.
For players not on steroids, they can hit the end of the line pretty quickly. Remember Dye's big second-half fade in his final year? Don't forget, while Konerko put up respectable numbers in 2012, many of them were registered in the first half or so of the season. He was pretty bad in the second half so now we're starting to approach a full year of struggles, though his wrist problems certainly could explain last year's fade.
