SAO LEOPOLDO/STARNBERG, November 18, 2022
Brazilian teenager Joao Fonseca headlined Thursday’s second-round action on home soil in Sao Leopoldo by reaching the quarterfinals of the Challenger Dove Men & Care Sao Leo Open. The 16-year-old wild card entry saved two match points to outlast World No. 245 Mariano Navone of Argentina 6-3, 1-6, 7-6(9).
In his second appearance on the ATP Challenger Tour, Fonseca had defeated Argentine Thiago Agustin Tirante in the first round and broke Navone’s serve four times to prevail after two hours and 23 minutes. Up next for the three-time winner on the ITF World Tennis Tour Juniors will be the clay-court event’s top seed Facundo Bagnis. The 103rd-ranked Argentine edged past Brazilian wild card Gustavo Heide 7-6(4), 6-3 in one hour and 49 minutes.
