MLB Closing Line Value by Sportsbook — April–June 2026
Across ~1164 MLB games and 19,714 moneyline prices from 9 Canadian sportsbooks, not one beat Pinnacle's closing line on average. The market-wide average was −2.16% CLV. theScore Bet gave up the least edge to the close (−1.67%); BetRivers priced furthest from it (−2.95%). A book's CLV here is a property of how soft its lines were, not a bettor's skill.
Book leaderboard — moneyline
Longer bar = further below Pinnacle's closing line. Every book priced below the sharp close on average, so all CLV is negative — the softest book simply gave up the least.
* Fewer than 3 months of data — the book entered the archive mid-window, so its sample is smaller.
Every market, pooled
On spread and totals markets the figure reflects price competitiveness at lines matched to Pinnacle's closing point — selections where the point moved are excluded, so this is not full line-movement CLV. The moneyline number is the true CLV.
Method: TrueLine snapshots odds across Canadian sportsbooks every 10 minutes. For each MLB game we take a book's last price before Pinnacle's close and measure closing line value against that close, then pool by book across April–June 2026 weighted by number of lines. The moneyline leaderboard is the headline number — it carries no point-matching caveat.
