Boris Becker says the consistency that has given him two Grand Prix titles in as many weeks is a reflection of his age.

"Even though I'm 21, I feel like I'm much older in the tennis business," the West German superstar said Sunday after beating No. 3 seed and two-time defending champion Tim Mayotte 7-6 (7-4), 6-1, 6-3 in the $602,500 U.S. Pro Indoor tournament in Philadelphia.

Becker won the $123,800 top prize by taking five straight games from 1-3 in the final set of the 2-hour, 27-minute match before 15,383 people at the Spectrum.

The victory came just a week after Becker won the Stella Artois Indoor in Milan, Italy, and improved Becker's record against Mayotte to 5-2 in Nabisco Grand Prix and Davis Cup matches.

***** At Oakland, Calif., Zina Garrison of Houston won her first tournament in two years by routing Larisa Savchenko of the Soviet Union 6-1, 6-1 on Sunday to capture the $250,000 Virginia Slims of California.

***** And at Lyon, France, second-seeded John McEnroe, showing flashes of the brillance that once made him the world's best tennis player, downed top-seeded Jakob Hlasek 6-3, 7-6 (7-3) Sunday to win the $291,000 Lyon Grand Prix tennis tournament.
