Adam Dunn has four home runs this spring after hitting a pair on Thursday against the Royals. Dunn hit a grand slam and two-run home run and finished 2-for-3 on the afternoon. "Where he's at and what he's doing and his mind and what he brings to the ballpark every day, that's the stuff I'm happy about," White Sox manager Robin Ventura said. Dunn hit .159 with 11 home runs in 122 games last season.
