Chet Lemon hit a two-run homer in the third inning and Jack Morris pitched a six-hitter last night in leading the Detroit Tigers to their sixth consecutive victory, a 3-1 win over the Yankees in New York.

Lemon hit his first homer of the season--into the upper deck in left field--off Tommy John (0-3) after Lou Whitaker reached first base on an error by third baseman Graig Nettles with none out in the third.

"He threw me the same pitch he struck me out on earlier," Lemon said, "a fast ball down and in. He surprised me the first time because he very seldom comes in on you. He got ahead of me, 1-2, and I was looking for a pitch away, and he busted it in on me. The second time, I was just looking for the baseball."

The Yankees have lost all three home games this season. The defeat dropped John's career record against Detroit to 7-15, his poorest mark against any American League team.

Morris (3-1) gave up a run in the first. Dave Collins tripled with one out and scored on a single by Jerry Mumphrey, but the Yankees managed only four singles thereafter.

After the first, the Yankees got only two runners as far as second against Morris, who retired 10 in a row from the fifth through the eighth.
