"Omar has been great since we got him. He does his role very well," Guillen said. "He has been playing pretty well. He hasn't had as much playing time, but every time he contributes to the ballclub.
"He's great in the clubhouse and in the dugout, a lot of people lean to him and talk to him. Like I said two months ago, 'This kid can play another two years.' He keeps himself in great shape."
Vizquel had 344 at-bats last season, hitting .276 with 30 RBIs as the team's regular third baseman during its 28-8 midseason hot streak. But Guillen explained the White Sox are not the team they want to be if Vizquel is getting that much playing time, as opposed to his designed reserve role.
In Sunday's 4-2 victory over the Indians, Vizquel picked up career hit No. 2,833, scored the go-ahead run in the sixth and made a slick defensive play at second to end the game.
