Ivan Lendl, in the middle of one of the most sensational streaks in tennis history, won 11 games in a row to rout Eddie Dibbs, 6-1, 6-1, yesterday to win the WCT Tournament of Champions in New York and go over the $1 million mark in earnings for the year.

Dibbs, the defending champion, upset top-seed John McEnroe Saturday, but appeared a helpless beginner against the strong and accurate strokes of the powerful Lendl.

Lendl, who required only 49 minutes to beat Dibbs, has won 89 of his last 92 matches. Since the U.S. Open last September, he has reached the final round of 18 consecutive tournaments, winning 15.

The first prize of $100,000 boosted Lendl's earnings for 1982 to $1,088,550, surpassing the record for a year of $1,008,742 set by McEnroe in 1980. In addition, Lendl will receive a fur coat valued at $43,000 for his mother in Czechoslovakia. In his six matches Lendl dropped 21 games.

Dibbs, who earned $40,000, won only 21 points in the match.

Johan Kriek teamed with Tracy Delatte to capture the doubles title from Dick Stockton and Erik van Dillen, 6-4, 3-6, 6-3. The winners split $18,000; the runners-up $8,000.
