Shawn Abner, the first player chosen in the 1984 amateur draft, homered twice and drove in seven runs as the New York Mets routed the Chicago White Sox, 17-8, yesterday in an exhibition game. Abner also doubled against White Sox starter Tom Seaver.

"The first thing I'm going to do is call my mom," Abner, 19, a nonroster player, said. "Seaver is her idol."

Seaver, making his spring training debut, gave up six runs on eight hits in three innings. He struck out two and walked none. "I accomplished the things I wanted to," he said. "I threw strikes and didn't walk anybody."

Carlton Fisk and Harold Baines homered for the White Sox, who were out-hit, 21-12.

*Tigers 3, Red Sox 0: Lance Parrish, Nelson Simmons and Kirk Gibson each drove in a run to back the combined five-hit pitching of four Detroit pitchers and a ninth-inning triple play in beating Boston.

In the Boston ninth, Mike Stenhouse and Mike Greenwell each singled off reliever Bill Campbell. Pinch-hitter LaSchelle Tarver hit a looping liner that shortstop Doug Baker caught at his shoetops. Her stepped on second to get Stenhouse and threw to first baseman Mike Laga before Greenwell could get back.

*Braves 8, Astros 5: Omar Moreno hit a two-run triple, sparking a five-run ninth-inning for Atlanta. Gerald Perry had three hits, including a homer. Gene Garber pitched a hitless eighth inning for the victory.

Tony Walker hit an inside-the-park homer for the Astros in the ninth in their first game under Manager Hal Lanier. The Braves played their first game under Manager Chuck Tanner.

*Giants 10, A's 6: Rookie Will Clark drove in four runs with a homer and a double and Jeff Leonard had three RBI for San Francisco. Juan Berenguer got the victory with four innings of two-hit shutout pitching.

*Angels 11, Padres 1: Reggie Jackson and rookie Wally Joyner each homered in California's victory over San Diego, spoiling the debut of Steve Boros as manager of the Padres.

*Cubs 7, Brewers 4: Back-to-back doubles by Chris Speier and Brian Dayett sparked a four-run Chicago rally that won it.
