"[Konerko] is pretty far away to playing first," Guillen said. "He's running the bases a little bit better, but right now, laterally it's going to be tough for him to move around."
Alejandro De Aza took grounders at first during Thursday's batting practice. But right-handed-hitting Brent Lillibridge, listed at 5-foot-11, will be at first on Friday.
"I feel bad for the infielders because they are throwing to a very small target," Lillibridge said. "I tell them to aim low. They are actually taking it seriously. I haven't seen anyone throw it very high."
