Jack Morris pitched a four-hitter for his third shutout of the season and Darrell Evans hit a two-run homer as the Detroit Tigers beat the Red Sox, 3-0, last night in Boston.

Morris (9-5) walked one and struck out three to increase his league-leading total to 96 strikeouts. It was his seventh complete game of the season.

"This is my first shutout here and I wanted it badly," said Morris, who last beat the Red Sox on June 8, 1983 and has a 6-10 career mark against them. "I felt strong and I was bearing down at the end. The Red Sox have been a tough team for me ever since I came up to the Tigers, but this makes up for a lot of things."

The Tigers got 10 hits off left-hander Bobby Ojeda (4-2), who went 7 2/3 innings. Detroit's Lou Whitaker had three hits.

Detroit took a 2-0 lead in the fourth. Chet Lemon led off with a single and scored as Evans hit a 2-1 pitch deep into the right field stands for his 14th homer. It was Evans' first homer off a left-hander this season.

In the eighth, Detroit made it 3-0 as Barbaro Garbey doubled, and after Mark Clear relieved Ojeda, Tom Brookens hit an RBI single.

Morris was seldom in trouble. Steve Lyons led off the Boston first with a single and took second on Wade Boggs' infield hit, but Morris got Jim Rice to ground into a double play and retired Bill Buckner on a grounder. Rice also grounded into a double play in the ninth, his 26th of the season.

Morris had been hit hard in his last start. "He's had a little bad streak, but he does that every year," Tigers Manager Sparky Anderson said. "You know he's going to come back. He's still the most dominant pitcher in the league. It's been that way for four or five years now."
