Butch Wynegar hit a three-run homer to lead the New York Yankees to a 4-2 opening-day victory yesterday over the World Series champion Kansas City Royals.
The largest opening day crowd in the history of Yankee Stadium -- 55,602 -- saw Lou Piniella make a successful debut as manager.
"It's real nice to win the first one," Piniella said. " . . . Now, we'll see if we can get a picture of the 1986 world championship team that we can hang beside the other ones in here."
Ron Guidry earned the victory, but left after five innings with a strained calf muscle in his right leg. His injury is not believed to be serious. He allowed two runs, both on Hal McRae's fourth-inning homer.
Wynegar, who had only five homers last season, hit his three-run home run in the second off Bud Black. Dave Winfield walked to start the inning and, two outs later, Dale Berra singled to bring up Wynegar, who hit a 3-2 pitch.
*Rangers 6, Blue Jays 3: In Arlington, Tex., Don Slaught hit a two-run homer and Larry Parrish connected on an opposite-field three-run homer to give Texas the victory in the opener.
Texas rookie right-hander Jose Guzman became the first major league rookie to start and win an opener since Fernando Valenzuela of the Los Angeles Dodgers did it in 1981.
Toronto's Dave Stieb took the loss in the managerial debut of Jimy Williams.
Slaught hit an 0-2 pitch over the left field wall after Parrish had singled in the fourth inning.
Rookie Pete Incaviglia delivered a double, Gary Ward singled and Parrish hit a three-run homer off reliever Mark Eichhorn in the fifth.
*Mariners 8, Angels 4: Jim Presley, whose two-run homer tied the game in the ninth inning, connected for a grand slam in the 10th to lift Seattle to victory in its home opener.
Seattle tied it, 4-4, when Alvin Davis doubled off Angels reliever Donnie Moore and Presley hit his two-run homer.
In the 10th, with Ken Forsch pitching, Phil Bradley walked and moved to third on a single by Ivan Calderon. After Gorman Thomas walked, Barry Bonnell fouled out before Presley hit his game-winning home run.
*Twins 3, A's 2: Mark Salas drove in one run and scored another to lead visiting Minnesota over error-plagued Oakland.
The A's took themselves out of the game by committing four costly errors, two by first baseman Dave Kingman.
Frank Viola pitched seven innings for the victory.
