George Bell drove in three runs with two doubles and Lloyd Moseby hit a home run, leading the Toronto Blue Jays to a 6-2 victory over the Kansas City Royals yesterday to spoil the world champions' home opener.

The game, played before a sellout of 39,033, was the first meeting between the teams since the Royals rallied from a three-games-to-one deficit to win the 1985 American League Championship Series.

Jim Clancy gave up six hits in seven innings, then gave way to Mark Eichhorn, who struck out the side in the eighth and set down the Royals in order in the ninth.

The Blue Jays got hits in each of the first eight innings, with Royals starter Mark Gubicza lasting only 3 2/3 innings. Tony Fernandez walked with one out in the first and came around on a grounder and a single by Willie Upshaw, who scored on Bell's first double.

The Royals picked up a run in the second, but in the third, Gubicza walked Rance Mulliniks and Upshaw and gave up a two-run double to Bell. Moseby hit his first homer of the season in the fourth.

*Tigers 7, Indians 2: Walt Terrell pitched a six-hitter and Detroit scored three runs on wild pitches and two on errors in Cleveland's home opener and the debut of newly acquired knuckle-baller Phil Niekro.

Niekro allowed seven hits and four runs, three of them unearned, in six innings in his first game for the Indians, who picked him up on waivers from the New York Yankees April 3.

*Yankees 3, Brewers 2: In New York, Mike Pagliarulo's tie-breaking two-run homer capped a three-run fourth inning that enabled Bob Tewksbury to win his major league pitching debut.

Tewksbury was tough in the clutch, stranding a runner in scoring position four times in beating fellow rookie Bill Wegman (0-1), who allowed four hits in 5 2/3 innings. Tewksbury surrendered nine hits in 7 1/3 innings.

*Red Sox 7, White Sox 2: In Chicago, Marty Barrett's two-run triple highlighted a four-run third inning to carry Boston to victory, making the White Sox 0-4, their worst start since 1974, when they lost their first five.

Roger Clemens gave up six hits over 8 2/3 innings. Joe Sambito recorded the final out for Boston.

*Twins 5, Mariners 1: Bert Blyleven kept Seattle scoreless until the eighth and Gary Gaetti and Tom Brunansky hit home runs as Minnesota won its first home opener since 1980.

Blyleven (1-0) lost his shutout bid in the eighth on an RBI single by Gorman Thomas. Ron Davis came in with the bases loaded, retired Jim Presley, then pitched a perfect ninth for his second save.

*Angels 10, A's 3: Bobby Grich, Reggie Jackson and Brian Downing hit home runs to back the combined seven-hit pitching of Ron Romanick and Ken Forsch as California won in Oakland.

Jackson's second homer of the year, a 400-foot shot off loser Rick Langford (0-1), was the 532nd of his career. Jackson is seventh all-time, two behind Jimmie Foxx.

Downing hit his third home run of the year, a ninth-inning grand slam off Tim Birtsas.
