BUENOS AIRES — Argentine club River Plate and Atletico Nacional of Colombia will face off Wednesday in a ‘winner takes all' second leg of the Copa Sudamericana final. Though the teams drew 1-1 in the first leg in Medellin, Colombia, the away-goals rule is not being used in this competition — the second most important in Latin America after the Copa Libertadores. Both clubs are also in contention for their national league titles. River Plate is second in the Argentine first division with one match to play Sunday. Racing Club leads River by two points. Atletico is contesting its league title with Atletico Huila and Santa Fe de Bogota. — AP
