DETROIT -- Carlos Guillen could return to the Tigers lineup for their nationally televised series finale against the Angels on Sunday night.

Guillen, who could barely walk Thursday, said on Saturday afternoon that playing on ESPN's Sunday Night Baseball is a strong possibility. The Tigers' new third baseman strolled around the clubhouse with ease, unlike the previous two days, and worked out in the team weight room with no pain to show for it.

Tigers manager Jim Leyland said Guillen, as of Saturday afternoon, had a 60 percent chance of starting Sunday.

"If he tells me he can play, he'll play," Leyland said.

Guillen has missed the last two games after fouling a pitch off his knee in Wednesday's win over Texas. He finished the at-bat, singling off the wall, and even stole second base. But the next day he had trouble walking.

The starting first baseman to start the season, Guillen's return would mark his first start at third base this season. Leyland announced on Tuesday that Guillen and former starting third baseman Miguel Cabrera would swap corner infield positions. Guillen has not started at third since 2003 when he played for Seattle.

With recent returns of Curtis Granderson, Placido Polanco and Gary Sheffield, Guillen's insertion back in the lineup would give the Tigers their entire starting lineup healthy for the first time this season.

Guillen has been one of the Tigers' most consistent hitters this season. He leads the team with a .338 average and eight doubles, to go with three home runs and 11 RBIs.
