Gemini · Jil Teichmann · 58.0%
Jil Teichmann holds a higher season win percentage (60.0% from a 12-8 record) compared to Lucie Havlickova (51.2% from a 22-21 record). Without ranking data or context on the level of competition, Teichmann is favored slightly based purely on her superior win-loss ratio.
google/gemini-3.1-pro-preview · Oct 15, 5:02 PM PDTClaude · Jil Teichmann · 56.0%
The only usable differentiators supplied are season singles records: Teichmann 12-8 (.600) versus Havlickova 22-21 (.512). Neither player has a current ESPN rank or ranking points in the package, so no ranking gap can be applied. The modest win-rate edge for Teichmann, plus the inference that her smaller match count may reflect participation at a higher tour level (while Havlickova's larger volume suggests more lower-tier play), supports a slight lean, but win percentage alone is a weak signal because opponent quality is unknown. Surface-specific form, injuries/fitness, head-to-head history, travel/scheduling, and market odds are all explicitly unavailable in this evidence scope, so the estimate stays close to a coin flip.
anthropic/claude-opus-5 · Oct 15, 5:02 PM PDTGrok · Jil Teichmann · 58.0%
Teichmann holds a superior 2026 singles record of 12 wins and 8 losses compared to Havlickova's 22-21 mark. This yields a higher win percentage for Teichmann. No ranking data is available for either player. Surface form, injuries, head-to-head results, travel, and market odds are unavailable per the evidence scope and are not factored into the estimate.
xai/grok-4.3 · Oct 15, 5:02 PM PDTGPT · Jil Teichmann · 58.0%
Using only the supplied immutable evidence, the main usable comparison is current-season singles record. Jil Teichmann is 12-8, a 60.0% win rate, while Lucie Havlickova is 22-21, a 51.2% win rate. No current rank is supplied for either player, so ranking cannot separate them. Teichmann’s materially better season win percentage supports making her the modest favorite, though Havlickova’s larger match sample adds some uncertainty rather than eliminating it. Surface form, injuries, head-to-head, travel, and market odds are unavailable in the evidence and therefore cannot be used.
