Jim Pugh and Rick Leach struggled more than four hours to beat Jorge Lozano and Leonardo Lavalle in a doubles match Saturday, giving the United States a 2-1 lead over Mexico in the Davis Cup World Group.

The American team won 6-4, 4-6, 7-6, 6-7, 6-4 in 4 hours, 24 minutes. The match included tiebreakers in the third and fourth sets.Play was often interrupted by rowdiness from the crowd and protests over calls, mostly from the Mexican players against Australian referee William McKewan.

At one point, chief referee Richard Long of Britain threatened to penalize the Mexican team one point because of Lavalle's often heated arguments with McKewan.

"Obviously it was very close. It could have gone either way," Leach said.

At San Antonio, Texas, Monica Seles lost a set for the first time in the tournament Saturday, but battled back to defeat Manuela Maleeva-Fragniere to set up a title match with Steffi Graf at the $225,000 U.S. Women's Hardcourt championship.

Seles, the top seed, defeated third-seeded Maleeva-Fragniere, 6-2, 2-6, 6-2. The second-seeded Graf cruised past unseeded Julie Halard, 6-0, 6-1, in the other semifinal.
