CLEVELAND (AP) — Justin Masterson took a shutout into the ninth inning, Matt LaPorta homered for the third straight game and the Cleveland Indians beat the Toronto Blue Jays 6-1 Thursday for their season-high fifth win in a row.

LaPorta's three-run shot highlighted a six-run fourth inning. The Indians' winning streak has come right after they lost seven straight.

Cleveland swept a four-game series for the first time since May 2009 against Tampa Bay. The Indians were swept at home by Toronto in a three-game series in May.

Toronto has lost five in a row, matching its worst skid this year.

Masterson (3-7) blanked the Blue Jays until Jose Bautista led off the ninth with a double and Aaron Hill hit an RBI single with one out. Frank Herrmann relieved with the bases loaded and got Jose Molina to bounce into a double play for his first major league save.

Masterson gave up eight hits, walked none and struck out five.

Shawn Marcum (7-4) didn't allow a hit in the first three innings, but fell apart in the fourth. The inning started with walks to Shin-Soo Choo and Carlos Santana, and a pair of wild pitches moved the runners into scoring position. After Travis Hafner struck out, LaPorta homered.

LaPorta, recalled from Triple-A Columbus on June 27, has hit four home runs. Shelley Duncan followed with a solo homer, the first time the Indians have hit back-to-back home runs this season.

Marcum's problems weren't over, either. Andy Marte singled and scored when Jason Donald's single bounced past left fielder Fred Lewis. Donald went to second on the error and scored on Trevor Crowe's bloop single to center.

Marcum, who allowed five runs and six hits, didn't come out for the fifth. He lost for the first time since June 9.

Toronto is 3-12 in its last 15 road games.
