A rebound 2012 season didn't provide peace to Adam Dunn's offseason.

Dunn won't be attending SoxFest this weekend because his wife Rachel is scheduled to deliver the couple's third child on Jan. 29.

"It's been different,'' Dunn said Monday from his Houston-area home. "I've been Mr. Mom with a lot of things."

One of Dunn's chores has been driving his two young children to school. But at least his kids are now old enough to attend school and allow him to prepare for 2013 while class is in session.

"That part of it has been good,'' said Dunn, who bounced back from a disastrous 2011 season to lead the Sox with 41 home runs and 96 RBIs last year. "I wouldn't say I had a great year.

"The end result was useless."

Dunn, 33, was referring to the Sox's 2-10 skid in late September that transformed a three-game lead into elimination from the American League Central and denied the 12-year veteran an elusive postseason berth.

"There are things I've started working on," said Dunn, who said a right oblique strain that sidelined him in early September took longer to heal this offseason than he expected. "(Hitting coach) Jeff Manto and I have been in contact. As we get closer to spring training, I'll check to see what he has in store for me."

As impressive as Dunn's power resurgence was, he batted only .204, up from .159 in 2011, and came within one strikeout of tying Mark Reynolds' major league record of 223. And in order to cut down his strikeouts, Dunn might have to alter one of his biggest strengths — working deep counts.

Dunn had 157 3-2 counts, including 55 that resulted in walks. But he struck out 65 times on 3-2 counts and was 12-for-102 (.118) in the other at-bats in 3-2 counts.
