"Manager Ozzie Guillen tweeted Thursday that his right eye is fine, one day after getting nailed with a foul ball that caromed off the backstop.

Now if he could only find a cure for the White Sox's woes that run deeper than designated-hitter Adam Dunn's frigid bat.

After missing his second game Wednesday because of a sore knee, Dunn is expected to return to the lineup Friday night for the start of an important American League Central showdown in Cleveland — where the Sox offense has sputtered since scoring 23 runs in the first two games here April 1-2.

Dunn — who is batting .158 with 124 strikeouts — played catch and shagged flies during batting practice Wednesday, so a trip to the 15-day disabled list would seem suspicious.

But at the same time, the Sox desperately need a spark for an offense that has scored three runs in its last two losses against the Royals and remain 4 1/2 games behind the Indians with 64 games left, prompting Guillen to embark on a two-minute rant late Wednesday night in which he declared that watching his listless offense hurt more than his swollen cheek and that he no longer will protect his underachieving hitters."
