Bobby Meacham had three hits and two RBI and Gary Roenicke hit a two-run home run to highlight a 16-hit offense, leading the Yankees to an 11-3 victory over the Seattle Mariners yesterday in New York.

Dennis Rasmussen (4-1) went seven innings for the win. He allowed eight hits, walked none and struck out seven. Dave Righetti and Tommy John added one relief inning each. Seattle's Mike Morgan (3-4) lasted 3 1/3 innings and gave up seven hits and three runs.

New York took a 5-2 lead in the fifth. Ken Griffey reached base on a fielder's choice and Roenicke, pinch-hitting for Mike Easler, hit his home run.

"I've said before, this is the best team I've ever played on," said Roenicke, who has six hits and four RBI in nine at-bats in his last three games after an early-season slump. "We've got more talent than any team I've been associated with, and I've been on world champions in Baltimore."

The Yankees broke the game open in the seventh, when they scored six runs off three pitchers. Ron Hassey had an RBI single, Butch Wynegar an RBI groundout, Meacham an RBI single, Rickey Henderson a two-run single and Don Mattingly an RBI double.

Henderson stole one base, giving him 600 for his career and placing him 15th on the all-time list.

*Red Sox 5, Rangers 4: George Wright's throwing error allowed Steve Lyons and Marty Barrett to score with one out in the bottom of the 10th inning, giving Boston a victory over Texas.

The Red Sox lost right-hander Al Nipper, who went out with a knee injury. Nipper left the game in the sixth with a four-inch gash on his right knee, suffered when he tagged out Larry Parrish at the plate. Nipper underwent an operation last night and will be out for about six weeks, the Red Sox said.

Bob Stanley (2-1) went one-third of an inning to earn the victory. Texas took leads into the bottom of the ninth and 10th innings, but could not hold either one. Greg Harris (2-6) took the loss.

With the Red Sox trailing by 4-3 in the bottom of the 10th, Lyons singled with one out. He advanced to second on an errant pickoff attempt by Harris. Barrett followed with a slicing drive down the right field line on which Wright attempted a diving catch.

He missed, then threw to third in a bid to catch Lyons. The ball went past third baseman Steve Buechele and between the legs of Harris, who was backing him up. It wound up in the Texas dugout, scoring both runners. It was Wright's second error of the game.

*White Sox 5, Royals 1: Carlton Fisk hit a three-run home run and Floyd Bannister gave up seven hits in seven innings to give Chicago the victory over visiting Kansas City.

The White Sox have won eight of 10 games since Manager Tony LaRussa received a reprieve from club management May 9.

Bannister (2-4) had six strikeouts and two walks, and Gene Nelson pitched the last two innings. Bret Saberhagen (2-4) took the loss.

The White Sox scored four runs in the third inning to take a 4-1 lead. Jerry Hairston and Harold Baines singled and Greg Walker blooped a single to left to score Hairston and tie the score at 1-1.

Fisk followed with his third home run of the season, just inside the foul pole in left field. It was his first home run since April 16.

Chicago got a run in the fifth to go ahead by 5-1. Tim Hulett hit a triple to center and scored on Wayne Tolleson's suicide squeeze.

*Blue Jays 10, Indians 2: In Toronto, Damaso Garcia, who last week burned his uniform in frustration, had a pair of two-run singles to lead the rout of Cleveland.

Jim Clancy (4-2) gave up seven hits in eight innings, striking out five and walking one. Since it won 10 in a row, Cleveland has lost five straight and nine of its last 10.

Toronto opened a 2-0 lead in the first on back-to-back RBI doubles by Willie Upshaw and George Bell. The Blue Jays stretched their lead to 4-0 in the second. Fred McGriff singled in his first major league at-bat and advanced to second when Ernie Whitt walked, and both moved up a base on Tony Fernandez's groundout.

Garcia -- who burned his uniform and cap after he made two errors that led to a pair of losses in Oakland -- lashed a single past the glove of third baseman Brook Jacoby.

Toronto blew the game open with four runs in the third.

*Twins 5, Brewers 3: Bert Blyleven pitched a four-hitter and Kirby Puckett hit a two-run double to lift Minnesota in Milwaukee.

Blyleven (4-3) struck out seven and walked none. It was Blyleven's third complete game and the 12th of the season for the Twins' staff. Tim Leary (3-4) took the loss.

*Angels-Tigers postponed: Yesterday's game between California and Detroit was called because of rain in Detroit. It has been rescheduled as part of a twi-night doubleheader Aug. 19.
