Nuno Borges vs Ethan Quinn: AI Prediction | Games, Spread, Aces & Double Faults

The model's edge for Borges comes mainly from recent form and his better serve/return combination. Borges carries a higher form index (54.22) and an Elo of 1691 compared with Quinn’s form 42.05 and Elo 1591, and those margins translated into a 4.6-point swing toward Borges for recent results and a further 3.5 points for serve & return. Borges’s surface strength index (21.16) also nudges him ahead of Quinn (16.90), contributing a 3.3-point surface fit advantage. Quinn’s age factor leans slightly in his favor (+4.5 points), but fatigue is a notable counterweight: Borges has spent 271 minutes on court in Mallorca versus Quinn’s 334, suggesting Borges is fresher going into the semis. Serving profiles on paper are comparable — mean serve indexes are nearly identical (Borges 96.73, Quinn 96.05) so no large serve-edge is expected, while Borges’s return index (92.40) is meaningfully higher than Quinn’s (86.00), a gap greater than five points and likely to influence short grass rallies. Over the last three matches both men have won all their Mallorca ties: Borges has three straight-set victories (including Struff and Mannarino) and generally shorter matches, whereas Quinn needed two long three-set battles and a straight-set win, indicating resilience but added wear.
