Daisuke Matsuzaka pitched his first major league complete game to start a four-game series between the AL's two top teams and the Boston Red Sox took their biggest lead in the standings in 12 seasons with a 7-1 win over the visiting Detroit Tigers last night.

Matsuzaka (5-2) 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.

The AL East-leading Red Sox improved to 26-11, while the AL Central-leading Tigers fell to 23-14 with their second straight loss. Both teams are 11-3 in their last 14 games.

Boston's 8 1/2-game division lead is its biggest since it held the same margin after play on Sept. 26, 1995. The idle New York Yankees dropped 8 1/2 games back, their largest division deficit since they trailed by nine games after play on May 7, 2005.

The Red Sox, now 20-0 when scoring at least five runs, tied it on David Ortiz' RBI single in the third off Nate Robertson (3-3). Coco Crisp singled home the go-ahead run in the fourth and Manny Ramirez added a run-scoring single in the fifth.

In other games:

* At Toronto, Troy Glaus hit a go-ahead two-run homer in the eighth inning and the Blue Jays rallied for a 5-3 victory over the Baltimore Orioles.

* At Arlington, Texas, Kevin Millwood came off the disabled list for the Rangers, gave up a first-inning grand slam to Casey Kotchman, then left after five outs with an aggravated hamstring in the Los Angeles Angels' 7-2 victory. Millwood, who had been sidelined since April 28 with a strained left hamstring, allowed four runs on three hits and three walks.

* At Oakland, John Buck hit a two-run homer in the top of the ninth inning to lead the Kansas City Royals to a 2-1 win over the Athletics.

Noteworthy

* Roger Clemens made 47 throws during a 7-minute session in the outfield during his first workout at the New York Yankees' minor league complex. He is scheduled for a bullpen session today and, barring any problems, will make his first minor league start Friday night for Class A Tampa. He could pitch for the Yankees during the last week of May or first few days of June. Clemens agreed to a $28,000,022, 1-year contract on May 6.

* Kansas City placed first baseman Ross Gload on the 15-day disabled list with a torn right quadriceps and recalled infielder Angel Berroa from Triple A Omaha. He will serve as a backup infielder. Berroa, the 2003 AL Rookie of the Year, was demoted to the minors late in spring training after coming into camp as the team's starting shortstop. But with Berroa having a rough spring, the Royals acquired Tony Pena Jr. in a trade with the Atlanta Braves and gave him the starting job. *
