Dunn originally missed two games (Sept. 1-2) due to the strain, returned to play three games and has since been out of the lineup again.
“I went and swung,” Dunn said prior to Wednesday’s game against the Detroit Tigers. “It felt like it did last Monday when I played. It’s just one of those things. I don’t even know how to kind of explain it. It feels fine when I pick up a bat and swing it in here. And then I go and try to hit, I don’t know if it’s because you tighten it up, it kind of grabs you.
“My thing is I don’t want it to (injure it worse.) If it happens as bad as it was now again, then I’m done. As bad as its sucks, I’d rather miss today and try again (Thursday).”
Dunn said not playing has been frustrating, especially with the White Sox in a pennant race. Chicago leads the Detroit Tigers by two games in the American League Central heading into Wednesday’s meeting.
“It’s terrible,” Dunn said. “This is the part of the season where I know everybody’s beat up, but this is the part of the season after the end of late season, this is what you want to be at -- September, playing meaningful games. Not being able to do anything, it’s awful. I’d rather be out there not doing anything than doing what I’m doing now.”
Dunn is batting .208 with 38 home runs and 88 RBIs this season. He leads the majors with 96 walks and 194 strikeouts and is tied for second in home runs.
