TOKYO -- Bernie Williams hit a solo homer and drove in three runs Saturday to lead the major league all-stars to a third straight win over their Japanese counterparts.

Barry Bonds went 2-for-4 with an RBI in the major leaguers' 12-7 victory in Game 6 of the seven-game exhibition series. The series is tied at 3.

Hideki Matsui went 1-for-5 and broke an 0-for-14 slump for the Japanese stars.

Williams homered off Shinji Mori in the eighth inning at Tokyo Dome to give the major leaguers a 10-7 lead. In the ninth inning, the major leaguers added a run on an error and a sacrifice fly by Junior Spivey.

"We came out swinging real well tonight and just kept adding on,'' manager Art Howe said. "After the first three games everyone was counting us out but we're right back in it and ready to go tomorrow.''

The major league stars haven't lost an all-star tour of Japan since 1990. They will try for their fifth straight series victory Sunday when Bartolo Colon of the Montreal Expos is expected to start. Koji Uehara, the winning pitcher in Game 1, is scheduled to start for Japan.

Japan's all-stars won the first three games of the series, but are winless since Bonds hit a grand slam in a 6-5 victory in Game 4 at Sapporo Dome.

Bonds hit an RBI single in a three-run second inning as the major leaguers took a 5-1 lead. He also hit a double off the wall in the top of the fourth, just missing his fourth homer of the series.

Miguel Batista earned the victory despite giving up four runs on five hits over 3 2/3 innings. Eric Gagne, who pitched the final two innings, earned a save and was named MVP of the game.

"It's always good to win,'' said Gagne. "They scored a lot and so did we and I just tried to do my best to keep them from scoring.

Jason Giambi had two hits and drove in two runs in the first inning.

"It was a curve up in the strike zone,'' Giambi said. "I think it's the first hit I've had here with a man on base.''

Ichiro Suzuki hit an RBI single in the fourth, and Eric Chavez had an RBI double.

Kazuo Matsui, who led off the bottom of the first with a homer, hit a two-run shot off Scott Schoenweis in the fourth.

"I knew it was out the moment I hit it,'' Kazuo Matsui said. "I can tell the major leaguers are starting to take this seriously.''
