Baseline · professional tennis

The tennis edges soft books haven't priced yet — proven against the closing line.

A calibrated model prices every ATP match. Pinnacle's closing line is the benchmark every pick is graded against — and the board flags the recreational books that disagree with the vig-free close by a validated 5–12%.

Forward record

35 picks graded since 2026-07-10 — too few to headline; the number lives on the ledger.

The standard we grade against

Every pick is graded against Pinnacle's closing line — the sharpest price in tennis. We don't claim to beat it; nothing reliably does. What we've validated is narrower and more useful: recreational books drift from that line, and our filter catches the drift. Every pick we post is settled at the posted odds and published, wins and losses alike. Hold us to it.
