CLEVELAND—Gavin Floyd, Carlos Quentin and the White Sox are excited to be back in the AL Central race.Floyd allowed four hits over 7 2/3 innings and Quentin hit a three-run homer in the fifth to give the Sox a key 3-0 division victory over the Cleveland Indians on Friday night.Floyd (8-9) earned his second straight win after going 0-4 over six previous starts. The right-hander struck out five and didn’t issue a walk for the first time in 19 starts.Floyd got help from a resurgent bullpen. Sergio Santos, the second reliever used by manager Ozzie Guillen, struck out Matt LaPorta on a pitch in the dirt with a runner on second in the ninth for his 19th save in 22 chances.Matt Thornton replaced Floyd with runners on second and third in the eighth. Pinch-hitter Orlando Cabrera drove his first pitch toward the gap in left-center, but left fielder Juan Pierre made a running catch near the warning track to end Cleveland’s best scoring threat.Thornton gave up a single to Michael Brantley in the ninth, then struck out Asdrubal Cabrera and got Travis Hafner to line out to center before yielding to Santos.The Sox improved to 12-20 against AL Central opponents by winning for just the sixth time in its last 15 games overall. The second-place Indians have lost five of seven and are 3 1/2 games ahead of the White Sox.Quentin’s 20th homer came off Carlos Carrasco (8-8), who worked out of several early jams. The right-hander stranded two runners in both the first and second innings and left the bases loaded in the third.Paul Konerko and Adam Dunn stroked one-out singles before Quentin belted a 2-1 pitch into the bleachers in left to make it 3-0.Quentin is a key reason why the White Sox are 5-1 this year against Cleveland. He is batting .500 [11 for 22] with three homers and 12 RBI in the season series.Floyd retired the first nine Indians. Ezequiel Carrera singled to open the fourth, but was erased on a nifty double play. First baseman Konerko scooped up a sharply hit ball by Brantley at his ankles and threw to shortstop Alexi Ramirez to force Carrera. Ramirez then sidestepped the sliding runner, jumped up and threw to first, where Floyd dug out the low throw.Carrasco gave up six hits and three runs over 6 1/3 innings, striking out six. After going 4-2 with a 1.90 ERA in June, the right-hander 0-4 with a 7.40 ERA in four July starts.
