Seventeen-year-old Boris Becker yesterday won his first Grand Prix title, producing 11 aces to defeat fourth-seeded Johan Kriek, 6-2, 6-3, in the $250,000 Queen's Club grass court tournament in London.

Becker, the 11th seed and the world's 29th ranked player, won $35,000 in the traditional Wimbledon warmup.

"It was a dream for me when I was 10 to win a Grand Prix final," Becker said. "This week was fantastic. I played my best tennis and beat a lot of good players."

En route to the final, Becker defeated Pat Cash and David Pate. Yesterday, Becker served five aces in his first three service games and in the sixth game broke Kriek on his fifth break point. He broke Kriek again in the eighth game.

Kriek, ranked 14th in the world, rallied in the second set with superb returns. The eighth game went to four deuces before Becker broke to lead, 5-3. He served out the next game at love, producing three big serves and a final ace for the victory.

Seconds later, Becker realized his parents were there, having flown in from West Germany. "I looked into the crowd and he (Becker's coach, Ion Tiriac) kept on pointing upwards until I saw them." . . .

In the women's $125,000 tournament in Birmingham, England, defending champion Pam Shriver took 43 minutes to rout Betsy Nagelsen, 6-1, 6-0, in the final. Shriver won her third singles title of the year with powerful serving and solid returns.

"She played much too well for me and there was little I could do about it," said Nagelsen, who won 12 points in the first set and 11 in the second. CANOEING

In Augsburg, West Germany, the U.S. men's C-1 team continued its dominance in the canoe events by capturing the gold medal on the final day of the 1985 world whitewater kayak and canoe championships.

Led by David Hearn, Jon Lugbill and Kent Ford, all residents of Bethesda, the C-1 team outdistanced its closest rival by more than 25 seconds.

The victory was the fourth straight by the United States in the C-1 team race in this international event.

The men's C-2 team, led by Bethesda residents Paul Grabow, Fritz and Lecky Haller and Fairfax resident Mike Garvis, helped the United States to a bronze medal.

Despite finishing the first of two runs in first place, the women's K-1 team, led by Cathy Hearn and Yuri Kusada of Bethesda, finished fourth.

Overall, the U.S. slalom team finished with four medals, including three gold. West Germany led with seven medals. BASKETBALL

The Pittsburgh Pirates waived shortstop Tim Foli, a key member of the 1979 world championship team, for the purpose of giving him his unconditional release. The team said it will activate center fielder Marvell Wynne from the 15-day disabled list.

"It is with regret that we make this move," General Manager Joe Brown said of Foli, 34, who hit .189 in 19 games. " . . . He has just reached the stage in his career where he can no longer help our club" . . .

Cincinnati Reds owner Marge Schott said she doesn't like the idea of granting female sportswriters access to locker rooms where male ballplayers shower and dress.

"There's been a ruling (by Commissioner Peter Ueberroth, opening the locker rooms) on it, but I'll tell you how I feel about that," Schott said to a group of Ohio editors. "We were taught at home that men should have their privacy." HORSE RACING
