Jake Peavy looks to snap a 10-start winless stretch when the Boston Red Sox visit the Seattle Mariners on Tuesday in the second contest of a three-game series. Peavy has lost five consecutive decisions since last winning on April 25 and has just one victory through 15 starts. Logan Morrison went 4-for-4 with two homers and four RBIs as Seattle matched its season high for runs scored in Monday's 12-3 rout of Boston.The Mariners had a slew of offensive heroes in the series opener as Kyle Seager had three hits and scored three times and Endy Chavez helped blow the game open with a three-run triple. Seattle has won four consecutive games to move five games above .500 and will soon have its offense bolstered with the return of outfielders Corey Hart (hamstring) and Michael Saunders (shoulder) and first baseman Justin Smoak (quadriceps). The Red Sox have lost four of their last five contests and have slipped 7 1/2 games behind the American League East-leading Toronto Blue Jays.TV: 10:10 p.m. ET, NESN (Boston), ROOT (Seattle)PITCHING MATCHUP: Red Sox RH Jake Peavy (1-5, 4.52 ERA) vs. Mariners RH Erasmo Ramirez (1-4, 4.62)Peavy's struggles continued in his last turn against Oakland as he allowed four runs (three earned) and five hits in 6 1/3 innings.
