For all the attention on Adam Dunn's struggles, White Sox center fielder Alex Rios also has been going through some tough times. Though bothered by a sore toe, Rios has been a major part of the team's ­inconsistent offense, hitting 2-for-17 in his last six games and 6-for-40 in his last 10.

Manager Ozzie Guillen took Rios out of the lineup Sunday and will sit him for several days in hopes of helping his mental approach.

''I think right now Rios is mentally very frustrated,'' Guillen said of the .199 hitter. ''He's very disappointed. I will give him a couple days break to hopefully recover and put his stuff back together. I plan to talk to him to tell him what the plans are. It's something that hopefully, when he comes back, he's ready to play.''

Guillen already had a talk with Rios about his ''body language'' after the veteran showed his frustration following an at-bat Friday. Guillen has said such displays are counter-productive.

Guillen has told Rios and Dunn, who is hitting only .178 and becoming the target of regular booing, to let go of the first two months of the season and look ahead.
