A whirlwind week in Buenos Aires that culminated with a maiden ATP title caught up to Joao Fonseca on Tuesday evening.
Back at the Rio Open, the 18-year-old home favorite was halted by Alexandre Muller in the opening round inside Quadra Guga Kuerten. Muller moved forward, 6-1 7-6 (4), to set a second-round meeting with eighth-seeded Tomas Martin Etcheverry. The 25-year-old notably went down the week prior to Fonseca after being on the receiving end of 34 winners.
