Astros at Giants Predictions, Odds and Betting Picks
Jesse M. Cox Published 10/08/2026
The Houston Astros are the clear moneyline side at -163 at DraftKings, with Hayden Wesneski bringing a 3.86 ERA into his matchup with San Francisco. The Giants are also dealing with major lineup losses, including Matt Chapman and Harrison Bader, while the Astros have won 7 of their last 10 games.
The bigger question is whether Houston can win by two runs at Oracle Park. The Astros sit at 60-59, while San Francisco is 49-69, and DraftKings has the total at 8 runs with the Over priced at -118. The cool 64°F to 66°F conditions and 10-mph wind should keep the park from adding much offensive help.
Astros vs Giants Game Preview
Houston enters this game at 60-59 and has gone 7-3 over its last 10 games. Wesneski gets the start after returning from Tommy John surgery, and his 3.86 ERA across his early work gives Houston a more stable pitching matchup than its recent injury-heavy rotation suggests. MLB also notes that this is only Wesneski's second game since returning from surgery.
Giants vs. Astros Game Highlights (3/31/25) | MLB Highlights
San Francisco sits at 49-69 and has significant holes in its lineup. Matt Chapman is on the 10-day IL with a severe abdominal strain, Casey Schmitt is out after knee surgery, and Daniel Susac is day-to-day after leaving Sunday's game with a left knee injury. Harrison Bader and Victor Bericoto are also unavailable, limiting the Giants' depth.
Blade Tidwell is scheduled to start for San Francisco with a 0-0 record and 3.18 ERA. Wesneski enters at 2-0 with a 3.86 ERA and 8 strikeouts, while both teams enter a three-game series at Oracle Park after Houston's road series against San Diego.
Moneyline Pick
The Astros ML is the play at -163. Houston has won 7 of its last 10 games, and Wesneski's 3.86 ERA gives the Astros a reliable starting pitching foundation against a Giants lineup missing Chapman, Bader and several other regulars.
San Francisco's 49-69 record makes the Giants +1.5 a less appealing side, especially against a Houston team priced as a clear favorite. At -163 at DraftKings, Houston is priced as the stronger team without requiring a run-line victory.
Pick: Astros ML (-163 at DraftKings).
Run Line Pick
The Astros -1.5 is the preferred run line. DraftKings has Houston at +104 on the standard 1.5-run line, giving the favorite a better price than its -163 moneyline.
The matchup supports the extra run because Houston has a 3.86 ERA starter against a Giants lineup missing several regulars. San Francisco's 49-69 record also makes it harder to justify laying less than two runs with the home team at +1.5.
Pick: Astros -1.5 (+104 at DraftKings).
Best Player Prop
- Hayden Wesneski strikeouts Over 4.5 (at DraftKings). Wesneski has already recorded 8 strikeouts in his return period and owns a 3.86 ERA entering his second start since Tommy John surgery. San Francisco's depleted lineup gives him a favorable path to five or more strikeouts.

Game Total Pick
The Under 8 runs is the stronger total position. DraftKings has the Under at -102, and the matchup features Wesneski's 3.86 ERA against Tidwell's 3.18 ERA, giving both starting pitchers ERAs below the posted run total's midpoint.
Oracle Park also brings cool 64°F to 66°F conditions with winds around 10 mph and almost no rain risk. San Francisco's injuries further reduce the Giants' offensive depth, while Houston's recent road schedule adds another reason to expect a controlled scoring environment.
Pick: Under 8 (-102 at DraftKings).
Best Trades for Astros vs Giants
Prediction market prices give Houston a 60% share price on Polymarket, compared with 41% for San Francisco. The spread and total markets are tighter, so the strongest opportunities center on Houston's win probability and a lower-scoring game.
- Astros game winner: YES at 60¢ on Polymarket. Houston's 60-59 record, 7-3 mark over its last 10 games and Wesneski's 3.86 ERA support the stronger side.
- Game total Over 8.5 runs: NO at 54¢ on Polymarket. The 3.86 ERA for Wesneski, 3.18 ERA for Tidwell and cool 64°F to 66°F weather all point toward a game staying below the higher 8.5-run threshold.
- Run in the first inning: NO at 51¢ on Polymarket. The market is nearly split at 51¢ on each side, but two starting pitchers with ERAs below 4.00 provide a reasonable case for a scoreless opening frame.

The -163 moneyline at DraftKings is the safer route, while the +104 run line offers more upside.
