The SP Open opens its main draw on the hard courts of São Paulo, and the first‑round contest between Spain’s Kaitlin Quevedo and the United States’ Whitney Osuigwe will be played on Quadra 2 at 5 p.m. EDT. Both players are starting their campaigns in the WTA event, and the match will set the tone for what follows in the tournament’s early stages. With a single set to win, the stakes are clear: a straight‑sets victory will see the winner advance to the second round, while the loser will be eliminated from the draw. The court assignment and the round’s pressure mean that a strong serve and solid return game could give either player an edge in this opening duel.
