Rick Porcello pitched a three-hitter for his AL-leading third shutout and Victor Martinez hit a grand slam, leading the Detroit Tigers over the Tampa Bay Rays 6-0 Wednesday night.
The Rays lost their fourth in a row.
Porcello (14-8) moved into a tie for the league lead in wins, retiring 20 straight batters after Ben Zobrist's double in the first.
Porcello walked none and struck out four in his first win since Aug. 2. He matched Miami's Henderson Alvarez for the major league lead in shutouts.
Martinez hit his fourth career slam, connecting off Kirby Yates in the seventh. Starter Jake Odorizzi (9-10) left earlier in the inning.
Wil Myers, the reigning AL Rookie of the Year, went 0 for 3 in his return to the Rays' lineup after missing 70 games because of a broken right wrist.
