Ron Guidry of the Yankees won his ninth straight last night, the best streak in the league, by pitching a six-hit 3-2 victory over the Minnesota Twins in New York.

"I had really good stuff," he said.

He hasn't started a season better since his 25-3 season of 1978. He is tied with Detroit's Dan Petry for the league lead in victories. He is 9-0 in his last 12 starts.

He struck out eight and walked none. His teammates got three runs off John Butcher (5-8) in the first inning by bunching four of their eight hits. Butcher has lost six of his last seven decisions.

"I don't want to talk about the first inning," Butcher said. "A couple of pitches in the first inning were up, but that's all."

Rickey Henderson and Ken Griffey opened the inning with singles -- Griffey had been zero for 19 -- then Don Mattingly doubled for a run. After Dave Winfield fouled out, Ron Hassey was intentionally walked, loading the bases. Don Baylor blooped a checked-swing single to center for another run and Willie Randolph's fly made it 3-0.

Guidry (10-3) faced nine batters in the first three innings and struck out five. In the fourth inning, Tom Brunansky homered. He has 18 but is only seventh among AL outfielders in all-star voting.
