Andre Agassi, 17, of Las Vegas beat Jimmy Connors yesterday as the veteran retired because of exhaustion trailing, 4-3, in the first set of the singles final at the Du Pont All American Tennis Championships in Amelia Island, Fla.

Connors, 35, appeared pale and dehydrated after the sixth game of the match and took a three-minute break to try to regain his strength in 100-plus degree heat. He lost the seventh game and was unable to continue.

"If there was any way I could have continued, I would have done so," Connors said. "{Andre} has such a great competitive spirit, and I hope all this talk about the lack of American tennis stars stops with him."

In the women's final, Pam Shriver, two points away from losing the match in the second set tie breaker, rallied to beat Stephanie Rehe, 1-6, 7-6 (8-6), 6-0 . . .

Top-seeded Gabriela Sabatini of Argentina defeated No. 2 seed Manuela Maleeva of Bulgaria, 6-4, 7-6, to win the title of the Pan Pacific Open . . .

In Geneva, Claudio Mezzadri defeated Tomas Smid of Czechoslovakia, 6-4, 7-5, in the Geneva Open. He became the first Swiss to win a Grand Prix title since Heinz Guenthardt at Toulouse, France, in 1983.
