Los Angeles Dodgers vs Seattle Mariners Prediction and Same Game Parlay picks, July 31, 2026

As the Dodgers gear up to face the Mariners, all eyes will be on Roki Sasaki, whose recent performances suggest he might hit a wall tonight. Despite the hype surrounding him, Sasaki has struggled with consistency, and the Dodgers' lineup is no easy task. They’re hitting a robust.274 against right-handers this season, capitalizing on pitcher mistakes with a keen eye. In addition, the Mariners' offense has shown signs of life lately, putting pressure on pitchers to navigate through their lineup carefully. Sasaki’s tendency to rack up pitches early could lead to an early exit, especially with the Dodgers' potent bats ready to capitalize. Given the model's prediction of just under 8 outs for him, taking the Under 18.5 seems like a savvy move, especially with the implied probability suggesting he’s more likely to falter than thrive. Expect a night where Sasaki may not get the chance to stretch his wings.

Mookie Betts (LAD) Under 1.5 Doubles (-1667)

As the Dodgers gear up to face the Mariners, all eyes will be on Mookie Betts, but betting on him to go over 1.5 doubles may not be the play. Despite Betts’ undeniable talent, he’s been a bit quiet in the extra-base department lately. Over the past few weeks, he’s found himself in a funk against lefties, managing just a handful of doubles in his last dozen games. Seattle’s pitching staff has been surprisingly effective, especially against right-handed hitters, holding opponents to a lower slugging percentage this season. Moreover, the Dodgers’ lineup, while potent, has seen more singles than doubles against the Mariners' recent pitching matchups. Given these trends and the fact that Betts is projected for just around 0.12 doubles, the under on 1.5 seems to be a savvy play. Sometimes, even the best hitters can find themselves in a slump, and tonight might just be one of those nights for Betts.

Andy Pages Under 2.5 Singles (-294)

As the Dodgers face off against the Mariners, all eyes will be on rookie Andy Pages. While he’s shown flashes of potential, his recent performance suggests that going under 2.5 singles is the play here. Over his last few games, Pages has struggled to find consistency at the plate, recording just a handful of hits against varying pitching styles. The Mariners’ pitching staff has been surprisingly effective, especially their starters, who excel in limiting hard contact. With a strikeout rate that hovers around the league average, they can keep hitters like Pages in check. Furthermore, the Dodgers’ lineup has been known to prioritize power over contact lately, which doesn’t bode well for a player looking to rack up singles. Given the current trends and Pages’ adjustment period as a rookie, backing the under on his singles seems like a prudent choice in this matchup.
