Tonight's probable starter for Houston Astros is Jason Alexander (ERA 7.3). They face Jack Leiter on the other side (ERA 4.61). Net pitching matchup is unfavorable by 1.2pp before bullpen and weather adjustments. Weather: DOME (neutral).

Frequently asked
What's the model's edge on Houston Astros @ Texas Rangers?
The Lakeshore Edge model rates Houston Astros at 46% to win or cover, versus FanDuel's implied 45% — a marginal edge of -0.8pt. That gap is what the model flags as a potential bet; the model has averaged +4.2pt CLV across 145 graded singles, meaning prices it picks tend to drift in the bettor's favor before close.
How likely is Houston Astros to win according to the model?
46% by the Lakeshore Edge model. Pinnacle, the industry's sharpest book at ~2% vig, has them at 46.1%; Polymarket's real-money traders price the same outcome at 45.5%. The model blends Elo, recent form, sport-specific factors (pitching, injuries, weather), and live line movement to land on that number.
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 145 graded singles, beating the close on 88% of them.
