ST. LOUIS -- Never has a home run hurt so bad for Adam Dunn as Tuesday night's 436-foot blast.
In the process of launching that eighth-inning drive, Dunn rolled his right ankle on the swing and sustained a slight sprain. The injury caused Dunn to be scratched from the starting lineup approximately 90 minutes prior to Wednesday's 1-0 loss to the Cardinals, although Dunn did pinch-hit in the eighth and hit into an inning-ending double play.
His status for Thursday is uncertain. With Clayton Kershaw starting Friday for the Dodgers, Dunn could have three straight games out of the starting lineup after playing every White Sox game of the season as of Wednesday.
"We did a lot of treatment, so hopefully [I'll play] tomorrow," said Dunn after the White Sox loss. "Swinging wasn't too bad. We had it wrapped so good. But running, not that I can move as it is, but you can imagine how bad it was when I can't move as it is, plus you add that. That would have been a disaster out there. There was no way I could have got out there and been productive today."
"We'll check him tomorrow," said White Sox manager Robin Ventura of Dunn. "But he wasn't getting down there very good."
Dunn was set to make his second straight start in left field, a move from his customary designated-hitter spot brought about by Interleague Play in a National League ballpark, and his third start at the position during the 2012 season. Dunn clubbed his 21st home run of the season on Tuesday to put him on pace for a career-high and franchise-record 56.
His 20th homer came during game No. 60 of this season against Houston, making him the fifth-fastest player in franchise history to reach that level. As Ventura reiterated on Wednesday, this present version of Dunn is much more a representative of a power-packed career than his 2011 debut with the White Sox.
"He has a track record. He has done it in years before," said Ventura of Dunn. "In this uniform, people just didn't see it last year. Now, you are seeing why he was brought here."
Dayan Viciedo replaced Dunn in left field and hitting third. Dunn first felt the ankle pain Wednesday morning and thought it was due to a couple of foul balls he hit off of his foot Tuesday. But that was not the case.
