Doug DeCinces and Bobby Grich hit home runs in the fourth inning to enable the California Angels to beat the Boston Red Sox, 4-1, yesterday in Anaheim, Calif.

Boston lost for the ninth time in its last 12 games.

Winner Mike Witt (10-7) walked one, struck out four and yielded five hits in eight innings. He fell behind on a leadoff homer in the third by Rich Gedman, his eighth, but the Angels got four runs in the bottom of the inning off Bruce Hurst (5-5).

Tigers 4, Royals 3: John Grubb's grounder with the bases loaded ended the game in Detroit.

Alan Trammell led off the 11th with a single off Steve Farr (7-2) and took third on Kirk Gibson's single. Lance Parrish was walked intentionally and, one out later, Grubb grounded to first baseman Steve Balboni, whose throw home was wide.

A's 2, Blue Jays 0: In Oakland, Eric Plunk (3-6) pitched two-hit ball for six innings and survived seven walks.

Dave Leiper relieved him and retired the only batter he faced. Then Dave Stewart, who started and pitched eight innings Wednesday, retired all five batters he faced. Joaquin Andujar, in his first regular-season relief appearance since 1983, pitched a perfect ninth for his first save.

Jose Canseco raised his major league-high RBI total to 81 with a single off John Cerutti (5-3).

Rangers 8, Indians 5: Scott Fletcher's RBI double, Pete Incaviglia's RBI single and a two-run error by Cleveland left fielder Mel Hall fueled a fifth-inning rally in Arlington, Tex.

With Fletcher on second and Incaviglia on first, Larry Parrish hit a fly to short left. Hall called off shortstop Julio Franco, then dropped the ball, as both runners scored.

Twins 8, Yankees 4: With Manager Ray Miller's job in jeopardy, Frank Viola and rookie Allan Anderson pitched a seven-hitter and got 15-hit backing in New York.

Anderson (3-3) allowed six hits in his five innings in relief of Viola, who left after a 1-hour 57-minute rain delay. Anderson struck out five and walked one.

It was the second straight victory for the Twins. Before last night's game, Twins owner Carl Pohlad visited the clubhouse, and on Friday, Twins President Howie Fox had said that Miller's status was being evaluated.

Mariners 5, Brewers 2: In Seattle, Danny Tartabull drove in four runs with a homer and a single, as Jerry Reed (4-0) won his third game in seven days.

The Mariners scored first on Tartabull's RBI single, but Milwaukee took a 2-1 lead in the second on Rob Deer's 18th homer. In the third, Alvin Davis had a run-scoring single, and Tartabull hit his 16th homer, with two on, off Bill Wegman (3-9).
