Frequently asked
What's the model's edge on Pittsburgh Pirates @ Houston Astros?
The Lakeshore Edge model rates Pittsburgh Pirates at 56% to win or cover, versus FanDuel's implied 51% — a meaningful edge of +5.3pt. That gap is what the model flags as a potential bet. The model has averaged +4.2pt CLV across 296 graded singles, meaning prices it picks tend to drift in the bettor's favor before close.
How likely is Pittsburgh Pirates to win according to the model?
56% by the Lakeshore Edge model. Pinnacle, the industry's sharpest book at ~2% vig, has them at 49.5%; Polymarket's real-money traders price the same outcome at 48.5%. The model blends Elo, recent form, sport-specific factors (pitching, injuries, weather), and live line movement to land on that number.
Why does the model disagree with the sportsbook?
FanDuel's price implies 51% on Pittsburgh Pirates, but the model has it at 56% — a +5.3pt gap. The model's reasoning is fully visible in the waterfall above; each adjustment stage is logged so the call can be audited after the game.
What's closing-line value (CLV) and why does it matter?
Closing-line value is how much your entry price beats the market's closing price on the same bet. If you pick a side at FanDuel -130 and the line closes at -150, the line moved 4pp toward your side after you locked in — that's positive CLV. CLV is the leading indicator of long-run profit because it's the metric that survives variance: a sustained positive CLV means you're consistently getting a better price than the consensus market settles on. Lakeshore Edge averages +4.2pt CLV on 296 graded singles, beating the close on 90% of them.
How has the model done on Pittsburgh Pirates picks recently?
Over the last 60 days the model has made 17 Pittsburgh Pirates picks, going 6-10 (38% win rate) averaging +4.67pt CLV with -32.44% ROI. Recent-team performance is a small slice; treat it as context for tonight's call rather than a guarantee.
