LASORDA EXTENDED: The Dodgers gave Manager Tom Lasorda a two-year contract extension through 1992, ending speculation he'd become manager of the Mets.

The decision was reached during a half-hour meeting of Lasorda, President Peter O'Malley and General Manager Fred Claire. But O'Malley insisted that the remarks by Peter Gammons on ESPN in no way influenced his decision.

"The rumors that circulated really had no effect on the timing," O'Malley said.

"There have been rumors about Tommy's future for the last five or 10 years, and speculation that he would manage in many different cities. I told a writer a month ago that 'if you could buy stock in Tommy's future, you should buy all you could.' We're delighted that the management team here will remain intact."

Lasorda, 62, has been a member of the Dodgers organization for 41 years.

LONG STRETCH: The Giants' 5-4 victory Saturday against Houston was the first time this season they won when they trailed after eight innings. San Francisco scored three runs in the ninth and two in the 10th. . . . Len Dykstra, the major leagues' leading hitter at.413, has a career-best 15-game hitting streak. It's the longest in the NL this season. . . . The Rangers played their shortest home game of the season Saturday: 2 hours 28 minutes.

HALF AND HALF: The Rangers were eight for 14 Saturday against left-hander Chuck Finley, bringing their batting average for the season against lefties to .289. They are hitting .224 against right-handed pitching. . . . The Indians' Chris James hit .122 in April and .321 in May. In the past two years he has hit below .200 in four months and above .300 in four months.

SORE POINTS: Glenn Davis, who tied a Houston record with four home runs in two games, had to leave Saturday's game with San Francisco in the bottom of the eighth with a strained left calf muscle. He suffered the injury running the bases in the top of the inning and is listed as day-to-day. . . . Angels infielder Donnie Hill strained his right shoulder in Friday's game and has been sent home to be examined.

MOVES: Mariners pitcher Scott Bankhead, a 14-game winner last year who has been bothered by shoulder problems, was placed on the disabled list for the second time this spring. Bankhead, 26, has an 0-2 record and an 11.08 ERA in four starts. The Mariners announced earlier this season that Bankhead would need shoulder surgery, but he decided to try to pitch again.

He was placed on the 21-day disabled list, retroactive to Saturday. He also was on the disabled list April 16 to May 18.

To replace Bankhead, the Mariners recalled pitcher Russ Swan from Class AAA Calgary. He was acquired from the Giants on May 24.
