KANSAS CITY -- After missing seven games with a right oblique strain, Adam Dunn returned to the White Sox lineup with a bang.

In his first three games back, Dunn went 5-for-12 with a double, a home run, two RBIs, a walk and three runs scored. The slugger got the start at designated hitter for the first time since his return in Tuesday's game against the Royals after playing the first three at first base. He said there's nothing to the position switch and that he's feeling good.

"When you're out there moving around, I'm going to have to make sure I'm really on top of it, stretch a little more than I normally do kind of in-between at-bats," Dunn said. "But it should be fine."

The experience was a rarity for Dunn, who's rarely missed extended time because of injury. He played in at least 152 games each season from 2004-10. A lengthy slump limited him to just 122 games a season ago, but Tuesday marked his 137th game.

He said the treatment he received for his recent injury was the most he's ever gotten in his career.

"I've never been hurt. I've never had anything wrong with me, and the things that I have had wrong with me I never got treatment for because it wasn't anything other than pain," Dunn said. "This is by far the most treatment I've ever got in my life."

Dunn also elaborated on the different kinds of treatment he received, including acupuncture and something he described as "they freeze you."

"We did everything to try to get it going as quick as possible. It was eight hours, probably not eight hours, but it felt like it," he said.

It seems to have paid off. Manager Robin Ventura said Dunn is looking good.

"He's looked fine. He looks normal. You just go by that," Ventura said. "And we don't see any more of the winces if he swings or does anything, so you just let him play."

Dunn went 0-for-3 with a strikeout and a walk in Tuesday's 3-2 victory.

De Aza back in lineup for KC opener

KANSAS CITY -- Alejandro De Aza was back in the White Sox lineup for Tuesday's series opener against the Royals.

De Aza sat out the previous two games following an 0-for-9 performance in the first two games of the series with the Twins.

"He just, in Minnesota, didn't look right," Ventura said. "Just tried to get him a day where he could work on it and get back in there. He's fine."

De Aza looked fine in his first at-bat, crushing a home run to lead off the game against right-hander Luke Hochevar. He finished 2-for-4 to help the White Sox grab a 3-2 victory.

The August addition of Dewayne Wise has crowded the the White Sox outfield. While Alex Rios is a permanent fixture in right field -- he's appeared in all but three games this season -- manager Robin Ventura has had to juggle De Aza, Wise and Dayan Viciedo in center and left field.

"They're all kind of doing their part," Ventura said. "There's only three spots out there. You keep them fresh and try to give them a good chance. You look at matchups and get them out there because they've all done something to get us here."

Wise entered play Tuesday batting .347 in September, and Ventura said he's played his way into more playing time. De Aza, meanwhile, has played in just 10 of the team's 15 games this month. Viciedo has made 13 starts this month, only eight in left field.

De Aza started in left field again Tuesday, his third start there this season after 115 starts in center. But, when Wise and De Aza are in the lineup together, Wise will play center and De Aza left.

Liriano to start Thursday's finale against Royals

KANSAS CITY -- White Sox manager Robin Ventura said that Francisco Liriano will be the starting pitcher in Thursday's series finale against the Royals.

It'll be Liriano's second straight start since rejoining the White Sox rotation. He went 2-1 in his first seven games with Chicago -- all starts -- but posted a 5.45 ERA. After one relief appearance, in which he surrendered two runs without getting an out, he returned to a starting role and pitched great on Sep. 15.

In that last start against his old team, the Twins, Liriano went seven innings and allowed just two runs on one hit. He struck out nine batters, a single-game high for him since joining the White Sox.

Liriano will oppose right-hander Jeremy Guthrie in the series finale.
