The world No.53, who is also in the doubles semifinals along with Nicole Melichar, had lost just 23 games in her six matches prior to the final showdown.

Earlier on Thursday, Paraguay drew 2-2 at home to Peru and Uruguay beat Chile 2-1 in Montevideo.
Adama said he had an excellent relationship with Ansu Fati, Spain's other player with African connections.
