ChatGPT prediction for Peyton Stearns vs Petra Marcinko, 22 January 2026.
I back Peyton Stearns at 1.71. Dimers' advanced model gives her a 57% chance, and previewers broadly expect the American to advance, while Petra Marcinko is the underdog at 2.27.
Stearns smashed Sofia Kenin 6-3, 6-2 — winning 86% of first-serve points and never surrendering serve — a form profile that targets Marcinko's clear second-serve vulnerability (47% points won) and the three breaks she conceded in round one. Stearns' seasoned hard-court resume (102-81) and aggressive forehand should control rallies.
This matchup offers value on Stearns: her serve and experience make her the most profitable $1 bet here, with a high chance to close in straight sets or a tight three.

Gemini prediction for Peyton Stearns vs Petra Marcinko, 22 January 2026.
Peyton Stearns enters this second-round clash as the clear favorite, and for good reason. Her dismantling of former champion Sofia Kenin in the first round, where she won 86% of first-serve points and was never broken, was a statement performance. Experts like Dimers give her a 57% win probability, and Last Word on Sports analysts are united in backing her.
While Petra Marcinko achieved a career milestone with her first Grand Slam main draw win, her 47% second-serve point win rate and three service breaks conceded against Maria highlight vulnerabilities that Stearns' aggressive forehand and powerful serve can exploit. Stearns' nine-year hard court record further underlines her composure. Given the 1.71 odds on Stearns, she presents a high-probability bet, despite Marcinko's 2.27 underdog value. Stearns is poised to advance.

Claude prediction for Peyton Stearns vs Petra Marcinko, 22 January 2026.
Peyton Stearns enters this second-round matchup with commanding momentum after her clinical dismantling of former champion Sofia Kenin 6-3, 6-2. Her first-round performance was particularly impressive, winning 86% of first-serve points without facing a single break of serve.
Marcinko, while celebrating her first Grand Slam main draw victory, showed vulnerability against Tatjana Maria, particularly on her second serve where she wins just 47% of points. The Croatian also conceded three service breaks in her opener, a weakness Stearns is well-positioned to exploit with her aggressive forehand exchanges.
The bookmaker odds of 1.71 for Stearns align with Dimers' model giving her a 57% win probability. With Stearns' extensive hard court experience (102-81 record) and the unanimous backing from analysts, she has both the statistical edge and momentum advantage.
Expect Stearns' powerful serve and dominant forehand to pressure Marcinko's vulnerable second serve, creating break opportunities throughout the match. The American should advance to the round of 32 with relative comfort.

Qwen prediction for Peyton Stearns vs Petra Marcinko, 22 January 2026.
Peyton Stearns enters this match as a strong favorite, backed by her impressive first-round performance against Sofia Kenin. Her aggressive forehand and dominant serve, which saw her win 86% of first-serve points, make her a formidable opponent for the less experienced Petra Marcinko. Marcinko, while showing resilience in her opening match, struggled with her second serve and conceded three service breaks, indicating potential vulnerabilities. The American's 102-81 hard court record over nine years and her 2-2 start to 2026 on the surface further solidify her as the more composed and prepared player. Given the odds, with Stearns at 1.71 and Marcinko at 2.27, the value and probability favor Stearns to continue her strong form and advance to the next round.
