"The White Sox wasted no time throwing right-hander Lucas Harrell into the fire of a burning road trip after calling him up from Class AAA Charlotte on Sunday.

After John Danks (0-8) was battered for nine runs and nine hits in four innings, Harrell came on to pitch in right-hander Tony Pena's customary long-relief spot. Pena was put on the 15-day disabled list with elbow tendinitis.

Harrell, 25, was 4-2 with a 3.54 ERA in nine games, including eight starts, at Charlotte. He hadn't pitched in five days, so he was good to eat some innings, which manager Ozzie Guillen praised him for.

Pena had been sidelined earlier this month with a tender elbow. He was 1-1 with a 6.20 ERA in 17 appearances. His last outing was Friday, when he allowed one run and three hits in the eighth inning.

"I have some inflammation in there,'' Pena said. "Hopefully, it will be OK in a couple of weeks.''

Guillen said he could stay with a six-man starting rotation if Pena were good enough to pitch in short relief. Harrell, who gave up four runs and nine hits, wasn't pleased with his first showing."
