MLB 5-leg parlay picks for July 31, 2026

As the Athletics host the Red Sox, all eyes will be on Jacob Wilson, but taking the under on his hits at 2.5 feels like the savvy play. Wilson has struggled recently, and with Boston’s pitching staff coming in hot, it's tough to see him breaking through. The Red Sox are riding a wave of momentum, boasting a solid bullpen that has limited opposing batters effectively. In his recent outings, Wilson's been grappling with consistency, often finding himself caught in tough spots against top-tier pitching. With an implied probability of just over 67% for him to go under 2.5 hits, the numbers are firmly in favor of this bet. Given how the Athletics have fared against strong pitching lately, and Wilson’s own recent form, it seems a tall order for him to find success at the plate tonight.

Rafael Devers (BOS) Under 4.5 Hits+Runs+RBIs (-175)

As the Padres host the Giants, all eyes will be on Rafael Devers, but I’m leaning toward the "under" on his 4.5 combined hits, runs, and RBIs. Devers has been solid, yet the Giants' pitching staff has shown remarkable resilience lately, with a team ERA hovering around 3.50 over the last month. Their ace has been particularly effective, limiting hard contact and keeping opponents off balance. Moreover, the matchup history isn’t in Devers’ favor. He’s struggled against the Giants’ left-handed pitchers, posting a subpar average in previous matchups. San Diego’s lineup has also been inconsistent, facing off against a San Francisco bullpen that thrives in high-leverage situations. All these factors suggest that Devers might find it tough to rack up those stats, making the under a compelling play for this game.

Jacob Wilson Under 3.5 Total Bases (-204)

As the Athletics host the Red Sox, all eyes will be on Jacob Wilson, but betting on him to go over 3.5 total bases might be a stretch. Wilson has shown flashes of brilliance this season, yet he’s struggled against left-handed pitching, and with Boston sending a southpaw to the mound, his chances diminish. The Red Sox have been effective at limiting opponents’ offensive production, especially against lefties, and Wilson’s recent form highlights a tendency to fade when facing tougher pitching. In the last few games, he’s managed just a couple of hits, and with Oakland’s lineup struggling to generate consistent support, runs could be hard to come by. Given Wilson's matchup and the way the A's have been hitting, betting on the under for his total bases seems like a prudent choice. Expect a tight game where he might fall short of that 3.5 mark.

Andy Pages Under 2.5 Total Bases (-161)

As the Dodgers prepare to face the Mariners, all eyes will be on young slugger Andy Pages. While his potential is undeniable, recent trends suggest he might struggle to clear the 2.5 total bases mark tonight. Over the last few weeks, Pages has faced a significant uptick in strikeouts, with opposing pitchers exploiting his tendency to chase high fastballs. Now, combining that with the Mariners' effective approach on the mound—especially their ability to limit hard contact—makes for a challenging night ahead for him. Plus, with the Dodgers’ lineup often leaning on their stars, Pages might not see as many opportunities to rack up bases. Given these factors, betting on him to stay under 2.5 total bases feels like a savvy move, especially with the odds leaning heavily toward this outcome based on his recent performance. Expect a quiet night for Pages in a matchup where the Mariners’ pitching reigns supreme.

Roki Sasaki Under 18.5 Outs Recorded (-256)

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.
