TORONTO -- Adam Dunn knows he's approaching history, but the slugger is trying to keep his mind off it.
The next home run Dunn hits will be the 400th of his career, and although the milestone is something he will be proud of, he just wants to make sure it happens at a critical moment of the game.
"I'm indifferent, I don't care. I don't want to sound like it is no big deal, because I know it is, but I really don't feel any different," said Dunn, who entered Thursday's contest tied with the Rangers' Josh Hamilton with a Major League-leading 34 homers. "I figure it's going to happen, hopefully it happens in a big situation."
Dunn, who has homered three times in his past three games, including a mammoth three-run blast that broke open a seventh-inning tie Wednesday, said he has been feeling good at the plate for the past four or five days.
It was the 15th time this season that Dunn hit a home run to tie a game or give the White Sox a lead.
When Dunn hits the milestone shot, he will join Paul Konerko as the only teammates in Major League history to hit their 400th homer in the same season.
With No. 400 right around the corner, Dunn was asked about his thoughts on reaching 500.
"Let me get to 400 first, that's a lot. You start talking that number, that's a good one," Dunn said.
Dunn, who is on pace to finish with a career-best 47 homers, has more than tripled his home run output from last season and has hit 11 of his 34 versus left-handers after failing to connect once against southpaws in 2011.
"He has been a friend of mine for a long time, we do everything together. It is not surprising at all, everybody has one of those years," said White Sox role player Orlando Hudson, when asked if he was surprised a player of Dunn's caliber is coming off such an poor season. "He's over it, came back out and he's having a great year this year.
"[We're] about to witness history again with his 400 home runs."
Dunn is tied with Al Kaline and Andres Galarraga for 50th on the all-time home run list.
