Buenos Aires:Star forward Martin Palermo headed in goals in each half to give Boca Juniors of Argentina a 2-1 win over Brazil's Sao Paulo in the Copa Sudamericana on Wednesday.
In other first-leg, second-round matches, Arsenal rallied past Goias 3-2, Botafogo defeated River Plate 1-0 and Lanus downed Vasco de Gama 2-0.
Palermo headed in his first off a centering pass from teammate Morel Rodriguez from 40 meters (yards) out in the 27th minute, beating Ceni inside the left upright.
In the 82nd, the Boca captain made a leaping header as he jumped in the air to take a centering blast from Neri Cardozo, the ball ricocheting off the left side of his head to angle into the net again past Ceni.
Sao Paulo's Borges caught the Boca's defense off guard in the final minute, racing into the area to find goalkeeper Mauricio Caranta well out of position as he flicked in his shot.
The goal leaves the Brazilian side better positioned for the deciding match of the two-leg series next Wednesday in Sao Paulo.
Joilson scored in the 44th minute at Rio De Janeiro to give Botafogo a win over River Plate of Argentina.
Botafogo, which defeated fellow Brazilian side Corinthians in the first round, hadn't played an international opponent since beating Juventus for the friendly Trofeo Teresa Herrera in 1996.
River Plate, making its debut in the second-tier South American tournament, played a tough, physical game from the start until Botafogo slowly took control.
The second leg is at River's Monumental Stadium in Buenos Aires on Sept 27.
Also at Rio De Janeiro, Carlos Casteglione and Paulo Garnier scored two minutes apart late in the second half and rallied Arsenal of Argentina past Goias.
Casteglione's and Garnier's goals in the 77th and 79th minutes followed a 76th-minute strike by Paulo Baier, his second of the game, that put Goias ahead 2-1.
Arsenal opened the scoring in the 15th minute when a deflected corner kick bounced across the penalty area and midfielder Israel Damonte volleyed it.
Goias equalized 25th minute on a free kick by Baier that left Arsenal keeper Mario Cuenca motionless and the Brazilians took the lead on another free kick by Baier.
The two will play the second leg in Argentina on Sept 26.
Jose Sands scored a late goal to seal Argentina's Lanus a 2-0 win over Brazilian side Vasco de Gama at Buenos Aires.
Agustin Pelletieri headed in the opening goal in the 32nd minute before Sands notched another in the 77th.
Sands also had a chance minutes after Pelletieri's header to score off a penalty kick, but Vasco goalkeeper Luiz batted the ball away for a difficult save.
Lanus travels to Rio de Janeiro, Brazil, next Wednesday.
The winner of each two-leg series will advance to the quarterfinals of the Copa Sudamericana, the biggest South American club tournament after the Copa Libertadores.
