Top-seeded Ivan Lendl, sharpening his game for Wimbledon, beat John McEnroe, 6-2, 6-4, yesterday to advance to the final of the Stella Artois grass court tournament in London against Boris Becker.

Becker, seeded second, breezed past third-seeded Stefan Edberg of Sweden, 6-4, 6-4, in 1 hour 25 minutes.

Lendl, the defending champion, needed five minutes less than that to dispatch McEnroe, serving his 11th ace on match point.

Lendl has spent the last two months playing on grass courts in his concerted drive to win at Wimbledon for the first time.

"Everything is geared to Wimbledon and playing better on grass," Lendl said.

McEnroe, who until this week had not played since mid-February because of shoulder problems, has won Wimbledon three times, but his grass court skills rarely showed yesterday. Lendl broke twice in the first set -- each time with backhand winners -- and never lost his serve.

"This was sobering reality today," McEnroe said. "He just outplayed me. His serve was really heavy, he was volleying solid and his returns are such that you have to be able to hurt him on his serve. Otherwise he returns well."

Dow Classic: In Birmingham, England, Zina Garrison advanced to the final with a 6-1, 3-6, 6-0 win over Nathalie Tauziat of France and will play Czechoslovakia's Helena Sukova, who stopped Rosalyn Fairbank, 2-6, 6-4, 7-5.

Florence International: Lawson Duncan breezed past Omar Camporese of Italy, 6-2, 6-3, to reach the final of the $250,000 event in Florence. Duncan will play Magnus Larsson of Sweden, a 6-4, 6-4 winner over Finland's Aki Rahunen.
