Closing Line Value Report — Thursday, March 19, 2026
A Thursday schedule brought 57 matches to the DeuceHQ CLV tracker on March 19, 2026. Markets were active across 5 tournaments, with Pinnacle registering 35 significant line moves. The full closing line value report below covers every match, movement, and result.
Significant Pinnacle Line Movements
The largest closing line movement of the day belonged to D. Galfi, whose odds shifted from 1.45 to 1.79 — an 19.3% move that indicates professional money entering the market before the match started. In the Miami 1/64-finals, this translated to a loss (3-6 7-6 6-7). Also notable was A. Sasnovich in Miami, where Pinnacle moved the line 16.0% (2.97 → 2.56). Bettors who took A. Sasnovich at the opening price secured CLV of +16.0%. Another notable move came in Miami where Y. Starodubtseva shortened 15.6%, suggesting the market initially underestimated the opponent.
Market-Beating Results: Upsets
That day produced 8 results where the underdog prevailed. The biggest came from Miami: M. Linette beat I. Swiatek 1-6 7-5 6-3 at 15.31. In Miami, E. Kalieva overcame 2.87 odds to defeat D. Galfi 6-3 6-7 7-6. 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 stayed with the favourite until the match started.

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 mkt column (versus market) 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, Pinnacle's opening price is used as the reference in place of your actual bet price — the CLV% therefore shows what you would have captured by betting at open rather than your individual entry point. 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 sourced in real time.
