Parlay: Boston Red Sox VS San Francisco Giants 2025-06-21

Same Game Parlay: Giants ML + Under 8 Runs
Odds: 3.38 (1.83 x 1.85)

Why This Works:
1. Giants ML (1.83 at FanDuel):
- The Giants have the third-best ERA (3.27) in MLB and a stellar 1.220 WHIP.
- Starter Hayden Birdsong (2.79 ERA) faces a Red Sox lineup that’s 22nd in the majors in batting average (.238).
- Rafael Devers’ addition boosts San Francisco’s offense, which should outscore Boston’s 9th-ranked offense (4.59 runs/game).

2. Under 8 Runs (1.85 at BetMGM):
- Birdsong’s 2.79 ERA vs. Dobbins’ 3.74 ERA creates a pitcher’s duel.
- Giants’ 3.27 ERA vs. Red Sox’s 4.59 ERA = a 1.32-run gap in pitching matchups.
- Oracle Park’s pitcher-friendly dimensions (12th in MLB for fewest runs per game) favor the Under.

Key Stat:
- Giants’ pitching staff has held opponents to 4+ runs in just 12 of 75 games this season (16%).

Risks to Consider:
- Red Sox’s 92 HRs (10th in MLB) could break the Under if they hit a long ball.
- Birdsong’s 7.2 BB/9 (vs. 2.1 K/9) could lead to a shaky start.

Verdict: A smart, value-driven parlay that leverages the Giants’ pitching dominance and the Red Sox’s struggles against strong arms. Take the Under at 1.85 for the best price.
