Two grand slams lift Matsuzaka (8-0)

BOSTON -- J.D. Drew and Mike Lowell hit grand slams to help Diasuke Matsuzaka remain unbeaten, and the Boston Red Sox completed a sweep of their seven-game homestand with an 11-8 victory over the Kansas City Royals on Thursday.

Drew and Lowell were the first Red Sox to hit slams in the same game at Fenway Park since Tony Armas and Bill Buckner did it Aug. 7, 1984. The last time Boston had two slams in a game was when the switch-hitting Bill Mueller hit both -- one from each side -- at Texas on July 29, 2003.

Boston’s seven wins come after it dropped the final four of a 4-6 trip. The Red Sox open a 10-game trip tonight in Oakland.

Jose Guillen went four for five with a solo homer and three RBIs, and Miguel Olivo had three hits and five RBIs for Kansas City.

Matsuzaka (8-0) gave up three runs and six hits, walked six and struck out seven in becoming the AL’s first eight-game winner.

Matsuzaka also became only the second Japanese-born pitcher to start a season 8-0 in the majors. Hideki Irabu started 1999 with eight wins for the New York Yankees.
