Matchup overview
Logan Webb will start for the Giants. He opened the season after action in the World Baseball Classic.
German Márquez draws the start for the Padres. Márquez finished 2025 at 3-16 with a 6.70 ERA.
Lefty-righty advantage
Márquez struggled versus left-handed hitters last season. He allowed a .311 average, a .396 wOBA, and 1.71 homers per nine innings.
Rafael Devers presents a notable matchup advantage. He generates a lot of damage against right-handed pitchers.
Hitter focus and projections
Rafael Devers is the primary offensive target in this game. The top bet is Devers to record over 1.5 combined hits, runs and RBIs.
Devers has produced strong contact against Márquez’s pitch mix. His average exit velocity on the last 10 balls in play was 94.5 mph.
Supporting bats
Jung Hoo Lee is another left-handed bat to watch. He hit .286 against Márquez’s three most prominent pitches and struck out just 7 percent of the time.
Matt Chapman is the home run pick. He is 6-for-15 lifetime versus Márquez, with four extra-base hits and three home runs.
Betting picks and reasoning
Best single bet: Rafael Devers over 1.5 hits + runs + RBI (-135). The matchup data favors him. Recent form also supports the play.
Same-game parlay suggestion: Devers over 1.5 H+R+RBI and Jung Hoo Lee over 0.5 hits, plus the Giants moneyline. This parlay combines matchup edges and contact ability.
Home run pick: Matt Chapman at +360. He has produced the hardest-hit balls for San Francisco early in the season.

- Moneyline: San Francisco -135 | San Diego +115
- Run line: San Francisco -1.5 (+125) | San Diego +1.5 (-145)
- Totals: Over 7.5 | Under 7.5
Trends and context
Devers cleared 1.5 combined hits, runs and RBIs in four straight games on zero days rest. That form is worth noting.
Webb is viewed as a quality-start type. The Giants should aim to supply early run support.
