Ozzie Guillen, then manager of White Sox, knew Adam Dunn was headed for a rough 2011 season last spring. Sitting in his Arizona office on the first day of spring training last year, Guillen was approached by then-hitting coach Greg Walker, who had just watched a batting practice session with Dunn, Paul Konerko, Carlos Quentin and A.J. Pierzynski. "He says 'We have a problem,'" Guillen said on "The Waddle & Silvy Show" on ESPN 1000. "I say 'What? Spring training is only a couple of days [old].' He says 'You've got to come out and see Adam Dunn's swing.' I said 'Don't worry about it. We've got a month and a half to get ready, go through spring training. Don't worry about it.'" That early batting practice session turned out to be a precursor for one of the worst major league seasons of all time. Signed to a four-year, $56 million deal in the offseason, Dunn batted .159 with 177 strikeouts in 415 at-bats. "People in Chicago, believe me, he tried everything in his power to get better," Guillen said. "He just had a bad year. Hopefully he will bounce back."
