Overview
- Defending champion Fonseca lost his opening match to Alejandro Tabilo 6-3, 3-6, 7-5 after a first-round bye at the Argentina Open.
- Post-match, he said he lacked conviction and confidence, noting his legs felt heavy and his body didn’t support the shots he wanted.
- He remains winless at Tour level in 2026 following a back issue that prompted Brisbane and Adelaide withdrawals and a first-round Australian Open loss to Eliot Spizzirri.
- The defeat costs him all 250 points from last year’s title, with a provisional drop from No.33 to No.37 in the ATP live rankings.
- He is set to compete at the Rio Open next week as the third seed, framing the tournament as a chance to reset on home soil.
