Where Sharp Money Moved the Line
Line movement analysis highlights three markets where Pinnacle adjusted significantly before close. C. Gauff led all movers at 23.3%, with the line shifting from 3.10 to 4.04 in Miami. Match outcome: a loss (2-6 6-4 3-6). T. Zidansek recorded 23.0% movement in Dubrovnik (2.68 → 3.48), meaning early bettors paid a 23.0% worse price than the closing line — a significant negative CLV outcome. Third place went to A. Rybakov in Houston, where odds lengthened by 16.3%, signalling uncertainty in the pre-match assessment.
Miami Champion and Pinnacle Closing Line
The headline match was the Miami final between A. Sabalenka and C. Gauff. Pinnacle opened A. Sabalenka at 1.42 and C. Gauff at 3.10. By the time markets closed, A. Sabalenka had moved to 1.29 — a 9.0% shift — while C. Gauff closed at 4.04. A. Sabalenka claimed the title with a score of 6-2 4-6 6-3. The closing line movement toward A. Sabalenka before the final suggests the market had priced in that the eventual champion was underpriced at open. Bettors who backed A. Sabalenka at open captured positive CLV (9.0%) as the market confirmed their edge.

Frequently Asked Questions — Closing Line Value in Tennis Betting
What is closing line value (CLV) in tennis betting?
Closing line value measures the difference between the odds you bet at and the final odds Pinnacle offered just before the match started. If you bet at 2.00 and the match closed at 1.80, you have positive CLV — you got a better price than the final market. CLV is widely considered the most reliable indicator of long-term profitability in sports betting, because Pinnacle's closing line incorporates all available sharp money and is the most accurate probability estimate available to the public.
Why does DeuceHQ use Pinnacle as the reference bookmaker?
Pinnacle is the industry benchmark for sharp money. Unlike most bookmakers, Pinnacle does not limit or ban winning bettors — they welcome sharp action. This means their odds reflect the true market consensus and are harder to beat. When Pinnacle's line moves significantly from open to close, it signals that informed bettors have entered the market. The vs market column on this page (labelled "vs mkt" in the table) compares Pinnacle's closing price to the average of other major bookmakers, showing where the sharpest market diverged from the wider betting market.
How is the CLV percentage calculated on this page?
CLV% measures the value of your bet relative to the closing line: ((odds you bet at - closing odds) / closing odds) × 100. On this page we use Pinnacle's opening price as the reference — the CLV% shows what you would have captured if you had bet at open. A positive CLV% means the odds shortened from open to close (you would have got a better price than the final market); a negative CLV% means the odds drifted. All calculations use Pinnacle's official open and close prices as recorded at the time each match began and are not updated after that point.
