CHICAGO (AP) -- Carlos Guillen singled home the go-ahead run in the 10th inning and the Detroit Tigers extended their longest winning streak in 77 years, rallying past the Chicago White Sox 6-5 on Wednesday for their 12th straight victory.

Guillen also hit a solo homer for Detroit, which hadn't won 12 in a row since 1934 when Hank Greenberg, Charlie Gehringer and the Tigers lost a seven-game World Series to the St. Louis Cardinals' famous Gas House Gang.

Jose Valverde finished up in the ninth to remain perfect in 44 save opportunities this year.

Closing in on an AL Central title, the surging Tigers rallied for three runs in the ninth off Chicago's bullpen to prevent rookie Dylan Axelrod from earning his first career win.
