In the ATP Challenger Sao Leopoldo on clay, local wild card Paulo Andre Saraiva Dos Santos (ATP #598) delivered a first-round upset over fifth seed Gonzalo Bueno (ATP #213), winning 6-2, 3-6, 6-4 on March 30 despite Bueno's 2-0 head-to-head edge, including a prior clay victory in Lima. Dos Santos capitalized on home crowd energy and Bueno's uncharacteristically low output of just 11 winners over 2 hours 12 minutes, extending his recent form amid a tough challenger schedule. Bueno's struggles highlight ranking volatility at this level, where surface familiarity and momentum often outweigh seeding; Dos Santos now faces the second round with potential for further run on familiar Brazilian clay.
