Daisuke Matsuzaka pitched his first major league complete game to start a four-game series between the AL's two top teams and the Red Sox took their biggest lead in the standings in 12 seasons with a 7-1 win over the Tigers on Monday night. Matsuzaka was outstanding for his second consecutive outing after three straight mediocre starts. He allowed just six hits, struck out five and walked none. He was dominant after Curtis Granderson's solo homer in the third. No other runners made it past second base.
