Cal Raleigh hit a grand slam for his major league best 27th home run and drove in six to tie a career high, Bryan Woo gave up one hit over seven innings, and the Seattle Mariners snapped Boston's six-game winning streak with an 8-0 victory over the Red Sox.

Cal Raleigh’s historic season continued Tuesday night with his second grand slam of the season to provide Woo a well of support in the Mariners’ 8-0 romp of the Boston Red Sox at T-Mobile Park. Woo was also the Mariners’ starting pitcher when Raleigh hit his first grand slam of the season, at Texas on May 2, in a 13-1 thumping of the Rangers.
