Closing Line Value Report — Tuesday, April 28, 2026
A Tuesday schedule brought 25 matches to the DeuceHQ CLV tracker on April 28, 2026. Markets were active across 6 tournaments, with Pinnacle registering 3 significant line moves. The full closing line value report below covers every match, every movement, and every result.
Significant Pinnacle Line Movements
The largest closing line movement of the day belonged to S. Sorribes Tormo, whose odds shifted from 2.09 to 1.99 — a 5.0% move indicating professional money entering the market before the match began. In the La Bisbal D'Emporda 1/16-finals, this translated to a win (6-4 2-6 6-3). Second on the list was A. Tomljanovic in La Bisbal D'Emporda, where Pinnacle moved the line 4.1% (1.76 → 1.83). Bettors who took A. Tomljanovic at the opening price secured a CLV of -4.1% — the line drifted against their opening price. The third notable move came in Madrid, where A. Blockx shortened 3.6%, suggesting the market had initially underestimated this player.
Market-Beating Results: Upsets
The day produced 6 results where the underdog prevailed. The biggest came from Abidjan 2: E. Sanogo beat I. Marrero Curbelo 7-6 7-6 at 6.36. In La Bisbal D'Emporda, A. Charaeva overcame 2.92 odds to defeat D. Galfi 6-4 6-2. These upsets saw little line movement before close — the market did not anticipate these outcomes. In such cases, underdog winners captured outcome value rather than closing line value; the market remained with the favourite right up until the first ball was struck.

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 began. If you bet at 2.00 and the match closed at 1.80, you have positive CLV — you secured 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 represents 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 mkt column on this page 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 by betting at open. A positive CLV% means the odds shortened from open to close (you would have obtained a better price than the final market); a negative CLV% means the odds drifted. All calculations use Pinnacle's official open and close prices sourced in real time.
