Seattle Mariners vs Los Angeles Dodgers Prediction, Preview & Same Game Parlay – 7/30/2026

The rubber game of a three-game set at Dodger Stadium arrives Thursday night with the Seattle Mariners and Los Angeles Dodgers dead even at 1-1 in the series after a pair of wild, homer-filled games. Seattle stole the opener 7-6 behind a five-home-run outburst, only to watch Los Angeles answer 4-2 the following night as Shohei Ohtani reached base four times. Now it comes down to a finale that pits a couple of inconsistent starters against one another, with the Dodgers still holding a comfortable lead in the NL West and the Mariners holding onto hope in the AL West picture.

Mariners vs Dodgers Model Projection

• Score Projection: Dodgers 6, Mariners 3
• Win Probability: Dodgers 65%, Mariners 35%

Bryan Woo gets the start for the Mariners in this contest. He enters this game with a 7-7 record and a 4.37 ERA. On the other side, Roki Sasaki has been erratic all year, carrying a 4.71 ERA and an 8.61 ERA over his last five outings that have included nine home runs allowed. That volatility usually favors the Mariners’ bats, but Los Angeles counters with the best OBP (.341) and lowest opponent batting average (.215) in baseball, a combination that tends to produce runs even against a pitcher throwing well.

Mariners vs Dodgers Same Game Parlay

• Leg 1: Dodgers -1.5 (+134)
• Leg 2: Over 8.5 total runs (-120)
• Leg 3: Shohei Ohtani to hit a home run (+214)

Total odds: +750

The reasoning behind this parlay starts with the run line. A Dodgers win by two runs or more is a fair ask against a Mariners offense averaging just 4.0 runs per game, and Sasaki’s homer-prone recent stretch adds risk that Seattle can close the gap late even if Miller keeps LA in check early. That same homer-prone tendency supports the Over, since either team piling up extra-base hits off a shaky Sasaki or a Mariners bullpen that has already given up plenty of long balls this season could push this one well past the total. Ohtani rounds out the parlay given his .976 OPS and 14 home runs at Dodger Stadium this year, plus a recent history of going deep against right-handed pitching like Miller’s.

Betting Trends & H2H

• Season series: Tied 1-1 (Mariners won 7-6 on July 28, Dodgers won 4-2 on July 29)
• Mariners record: 53-56 overall, 23-33 on the road
• Dodgers record: 68-40 overall, 32-20 at home
• The over/under is 1-1 through the first two games of this series.

Stat Comparison

The numbers make the picture fairly clear: Los Angeles owns real advantages in on-base percentage, power, and raw talent up and down the roster, while Seattle’s one true edge is a starting rotation that has quietly outperformed its record. With both pitchers struggling for consistency, and Dodgers’ offense waiting behind Sasaki, the deeper roster should be enough to take the series finale.
