Rookie Wade Boggs delivered his first major league home run with one out in the bottom of the 11th inning last night in Boston to lift the Red Sox over Detroit, 5-4, for the Tigers' ninth straight defeat. Boston had tied the game on Dwight Evans' two-out, two-run homer in the ninth.

Boggs, last year's International League batting champion, sent a 3-2 pitch from Dave Tobik (2-2) into the left field screen as the Red Sox won their eighth straight game against Detroit and their 23rd over the Tigers in their last 26 meetings at Fenway Park.

Mark Clear pitched four innings of two-hit shutout relief to improve his record to 6-2.

With Detroit ahead, 4-2, in the ninth, Rick Miller singled to left with one out, and after Tony Perez struck out, Evans put a 1-0 pitch over the fence into the Red Sox bullpen in right field for his fourth homer.

The Tigers had taken the lead in the eighth inning on a two-run double by Rick Leach. Leach, who had only five hits in 23 at bats entering the game, went three for four and drove his tie-breaking hit off the left field wall off Clear. The Tigers had loaded the bases on a double by Kirk Gibson, a single by Lance Parrish and a walk to Larry Herndon.
