ARLINGTON -- Even though he has been out of the lineup the past three weeks -- 17 games -- with lower back spasms, Detroit Tigers infielder Carlos Guillen is still trying to return this season.
At this point in the season, though, several teams, especially ones out of postseason contention, opt to shut down their players rather than have them risk further injury.
That, however, isn't a factor to Guillen, who was hitting .286 with 10 home runs and 54 RBIs before being sidelined.
"I'd like to finish on the field, that's my goal," Guillen said. "I don't know if I can, it just depends if I feel good."
The switch-hitting Guillen, who could be ready to play as early as Tuesday, is able to take swings comfortably from the left side, but not from the right side.
Detroit manager Jim Leyland said that Guillen would not come back as a designated hitter.
"If he's able to hit, I'd assume he'd be able to field," Leyland said. "I'd like to get him back out there, but I don't know how long it's going to be."
The Tigers were also without shortstop Edgar Renteria on Monday night. Renteria left the second game of Sunday's doubleheader against the Chicago White Sox with a pectoral injury.
"I took him out because he said he couldn't go," Leyland said.
Ramon Santiago started at short for Detroit on Monday.
