Hideki Matsui and Ryan Sweeney homered during a nine-run fourth inning as the Oakland Athletics collected a season-high 17 hits en route to a 13-4 trouncing of the visiting Tampa Bay Rays on Wednesday night.

Matsui drove in five runs, and Jemile Weeks recorded three hits, three runs and three RBIs for Oakland, which has won seven of its last eight home games and eight of 12 overall.

After Matsui opened the scoring in the third with an RBI double, the Athletics registered their biggest inning of the season in the fourth against James Shields (9-9), who yielded 10 runs in four innings after surrendering only nine over his previous four starts.

Matsui launched a three-run homer, Sweeney belted a two-run shot and Scott Sizemore plated two with a triple as Oakland set a season high with seven hits in the inning. Matsui added a run-scoring single in the fifth for his 16th RBI in his last nine games.

Weeks hit an RBI triple and scored in the fifth before lifting a sacrifice fly an inning later for a 13-0 cushion.

Oakland starter Trevor Cahill (9-9), who had received two runs of support or less in each of his previous nine starts, rebounded from the worst outing of his career. The 23-year old allowed four singles over 7 1/3 scoreless innings to snap his four-game losing streak.

Matt Joyce hit a two-run homer during a four-run ninth for the Rays, who have lost seven of eight on the road and six of seven overall.
