2. Market Behavior & Price Dynamics

Historical Price (Probability)

Outcome probability
Date
This prediction market, which tracks the probability of Andrey Rublev winning his match against Alejandro Tabilo, opened with Rublev as a slight favorite at 55.0%. The price has since trended upwards, currently sitting at 63.0% after reaching a peak of 76.0%. The most significant price movement was a sharp 10.0 percentage point spike on March 20, from the opening price of 55.0% to 65.0%. According to the provided context, there was no apparent news or external event to trigger this initial jump in probability for Rublev. This suggests the move may have been driven by early market dynamics or a small number of influential trades rather than a specific development.
Volume analysis indicates that conviction grew significantly as the match approached. The initial price spike occurred on very light volume, with only 44 contracts traded. However, volume surged to over 144,000 contracts the following day as the price corrected slightly to 63.0%. This high volume suggests the market is actively engaged and that the current price level reflects a broad consensus among a large number of participants. Overall market sentiment has consistently favored Rublev, the higher-ranked player, never dipping below the 55.0% opening price. The price action suggests traders believe Rublev has a roughly 2 in 3 chance of winning.
From a technical perspective, the market established an initial support level at its opening price of 55.0%. The peak price of 76.0% has so far served as a point of resistance. The current price of 63.0% appears to be a key level of consolidation, supported by the highest trading volume seen in the market. This indicates that while bullish sentiment drove the price up initially, a more stable consensus has formed in the low-to-mid 60s as the match draws nearer and more traders have entered the market.

5. Can Andrey Rublev's Performance Metrics Be Calculated Under Specific Conditions?

Matches Meeting Criteria0 (zero found) [^]
First-Serve Win PercentageNot available (no matching data) [^]
Break Point Conversion RateNot available (no matching data) [^]
Extensive research was conducted for specific tennis statistics for Andrey Rublev. This web research aimed to determine Andrey Rublev's first-serve win percentage and break point conversion rate. The analysis was focused on his last 15 outdoor hard court matches against left-handed opponents ranked outside the top 30. However, no matches were identified within his recent record that simultaneously satisfied all these specific criteria [^].
The requested specific statistics cannot be provided due to data absence. Consequently, the specific statistics for this precise scenario are unavailable. The absence of data under these exact conditions means that the first-serve win percentage and break point conversion rate are undefined and cannot be calculated based on the information gathered [^].

6. Was There a Significant Polymarket Price Spike for Rublev vs Tabilo?

Rublev Polymarket Moneyline68¢ (approximately 68% probability) [^]
Polymarket Volume$10.5K [^]
Rublev ML Movement (March 20)Minor, from ~1.30 to 1.50 [^]
No significant 10.0 percentage point price spike was observed on March 20. There is no evidence of a substantial 10.0 percentage point (pp) price spike on March 20 for the "Rublev vs Tabilo" prediction market on Polymarket. Furthermore, web research did not indicate a corresponding sharp line move initiated at a sportsbook like Pinnacle. Current Polymarket data for this event shows Rublev priced at 68¢, reflecting an approximate 68% probability, with a total trading volume of $10.5K [^]. This pricing aligns with traditional sportsbooks, such as BetMGM, which lists Rublev at -295, implying approximately a 75% probability [^].
Actual odds movements on March 20 were minor, not a sharp shift. Analysis of odds movements on March 20 from sources like Tennis Explorer revealed only minor adjustments for Rublev's moneyline, shifting from approximately 1.30 to 1.50 [^]. This minor adjustment does not represent a sharp 10pp shift in Polymarket terms, which would be equivalent to roughly 10¢. The low trading volume of $10.5K on Polymarket for this event strongly suggests that market activity is predominantly driven by retail participants rather than significant capital from sharp bettors [^]. Consequently, any observed price movements would more likely correspond with volume originating from retail-heavy platforms rather than a substantial line move initiated by a sharp sportsbook.

7. What is Alejandro Tabilo's Win Rate with Short Acclimation After Travel?

Win Percentage (specific conditions)Not available due to lack of granular travel data [^]
Sets Won/Lost (specific conditions)Not available; specific acclimation times not documented [^]
General Match Results AvailabilityAvailable for Indian Wells [^], Miami [^], Montreal [^], Cincinnati [^]
Data on Tabilo's specific performance under strict travel conditions is unavailable. Specific historical performance data, including win percentages and sets won/lost, for Alejandro Tabilo in the opening round of North American Masters 1000 events when he has had less than 72 hours to acclimate after intercontinental travel, is not available. While general match results for his opening round appearances at tournaments such as Indian Wells [^], Miami [^], Montreal [^], and Cincinnati [^] are accessible, the research did not find the necessary granular details. These missing details include prior tournament locations, exact travel dates, or specific acclimation times, all of which are crucial for calculating statistics under the precise conditions specified.
Critical travel details are absent, preventing precise statistical analysis. The absence of these critical details makes it impossible to calculate statistics under the precise condition of less than 72 hours acclimation after intercontinental travel. Alejandro Tabilo is based in the Americas (Chile/South America), and his typical travel patterns often involve movements from South American clay court events to North American hardcourt Masters tournaments in March. This regional travel schedule suggests that the time taken to acclimate between continents would likely exceed a 72-hour window, indicating such occurrences might be rare or simply not extensively documented in public data.

8. Are Detailed Rublev Backhand Unforced Error Stats Publicly Available?

Rublev's backhand unforced error rate (vs. Tabilo first serve)Not publicly available [^]
Rublev's average backhand unforced errors (vs. left-handers, 12 months)Not publicly available [^]
Availability of granular match statistics (Basel 2024 match)Not detailed enough for specific wing/shot type [^]
Specific backhand unforced error rates from Rublev's Basel match are unavailable. The precise unforced error rate for Andrey Rublev's backhand wing when returning Alejandro Tabilo's first serve in their 2024 Basel match, which occurred on October 23, 2024 [^], is not publicly accessible. Standard match reports and statistical summaries from sources such as Sportytrader, TNT Sports, and Tennis Majors offer general results and aggregated statistics, but they do not provide a detailed breakdown of unforced errors by specific wing, shot type, or the type of serve received [^].
Granular unforced error data is generally not available for comparison. Due to this lack of specific granular data, a direct comparison of this particular unforced error rate to Rublev's average against other left-handed players over the last 12 months is not feasible. Even advanced resources like Tennis Abstract's Match Charting Project, while detailed for many matches, do not include or readily compute aggregated statistics at this precise level for backhand unforced errors on first serve returns against left-handers [^]. Therefore, the requested precise data points are not publicly available through standard or specialized tennis statistics platforms.
