Bookmakers slightly favor Pedro Boscardin Dias over Mariano Kestelboim, with recent clay-court Challenger results and a higher current ranking tipping the odds toward the Brazilian at roughly 1.65 vs 2.20 for the Argentine, though exact market prices may shift closer to first serve; this edge comes from Boscardin Dias’ stronger hold/break stats over the past month with DexWin - Best Odds on Your Favourite Sports.

The match between Pedro Boscardin Dias and Mariano Kestelboim in the Buenos Aires tennis event is scheduled to start at 4:00 PM local time on 12 January 2026, which corresponds to 7:00 PM UTC assuming Buenos Aires is on Argentina Time (UTC-3) with no daylight-saving adjustment at that period.

The match is set to be played at a Buenos Aires tennis venue on outdoor clay courts, typical for tournaments in the Argentine capital, with medium-slow conditions that favor baseline consistency and heavy topspin; the stadium usually holds a few thousand spectators in an intimate setting with stands close to the court to generate strong home support for local players like Kestelboim.

Prediction: Pedro Boscardin Dias is projected to win in straight or four sets on clay, given his more consistent recent Challenger-level performances and better service games, making a win at around 1.65 fair value, while spread or handicap markets slightly favor him by several games, although Kestelboim’s home advantage could tighten early sets and create opportunities for live-betting swings.

Pedro Boscardin Dias and Mariano Kestelboim have limited or no official ATP main-tour head-to-head meetings recorded, and any prior encounters are likely at ITF or Challenger level with minimal public data, so this match is effectively treated by analysts as a first meaningful matchup, placing greater emphasis on each player’s recent form on clay rather than historical duels.
