Australia's Alex de Minaur put an end to Brazilian talent Joao Fonseca's challenge at the Miami Open, outlasting the 18-year-old 5-7, 7-5, 6-3 in an enthralling contest. Attendance on stadium court had been sparse throughout Monday, but the Hard Rock Stadium turned into a mini-Maracana Stadium for Fonseca's match, complete with Brazilian flags and football-style chanting. Fonseca brought his energetic brand of ultra-attacking tennis, but De Minaur was up to the challenge, coping with both the blistering forehands and the partisan crowd.
