MLB 5-leg parlay picks for August 13, 2026

As the Miami Marlins host the Pittsburgh Pirates, all eyes will be on Jake Mangum. While he’s been a sparkplug at times, recent trends suggest he might struggle today. The Pirates’ pitching staff has tightened considerably, with a 3.40 ERA over the past two weeks, effectively silencing opposing bats. Mangum, despite his potential, has struggled against left-handed pitching, hitting just.214 this season in those matchups. Moreover, the Marlins have been inconsistent at the plate, averaging just over three runs in their last five games. With the odds leaning toward him securing under 1.5 hits, the combination of Pittsburgh's solid pitching and Miami's recent offensive woes paints a compelling picture. Under these conditions, it feels prudent to bet on the under for Mangum today. Keep your expectations in check; the under looks like a savvy play here.

Otto Lopez (MIA) Under 1.5 Hits (-256)

As the Marlins take on the Pirates, all eyes will be on Otto Lopez's performance, and betting the under on his hits makes a lot of sense. Lopez has been struggling at the plate lately, with a worrisome dip in his batting average that’s left him prone to groundouts and weak contact. The Pirates' pitching has tightened up, especially against left-handed hitters, which bodes ill for Lopez, who hasn’t shown the ability to consistently find gaps. Moreover, Miami’s lineup is known for their feast-or-famine approach, often leading to lower hit totals against solid arms. With the Pirates' recent run of form, they’ve been managing to contain opposing batters effectively. Given the combination of Lopez's current slump and the Pirates’ pitching prowess, it seems reasonable to expect him to stay below the 1.5 hit mark this game. Keep an eye on the trends; this could be a pivotal moment for Lopez to turn things around, but betting the under seems wise for now.

Masataka Yoshida Under 1.5 Hits (-250)

As the Toronto Blue Jays gear up to face the Boston Red Sox, all eyes will be on Masataka Yoshida, but the betting angle here leans heavily toward the under on his hits. Despite his impressive talent, recent trends suggest a challenging night ahead against the Blue Jays' formidable pitching staff. With a solid 3.69 ERA over the last month, Toronto’s rotation has been formidable, particularly at home where they thrive under the spotlight. Yoshida, while capable, has struggled against pitchers who can command the strike zone, and today’s matchup is no exception. He’s only managed to reach that 1.5 hit mark in a fraction of his recent games, often finding himself overmatched by elite pitching. Given the odds favoring the under and the implied probability sitting at a striking 71.4%, it seems prudent to expect Yoshida to have a quiet night at the plate in this pivotal matchup.

Griffin Conine (MIA) Over 0.5 Hits+Runs+RBIs (-192)

As we gear up for the matchup between the Miami Marlins and the Pittsburgh Pirates, keep an eye on Griffin Conine. The young slugger has been on a tear lately, showcasing his ability to find gaps and get on base. With the Marlins’ offense heating up, it’s hard not to notice how they’ve been piling on runs, especially against teams with shaky pitching like the Pirates. Pittsburgh’s rotation has struggled with consistency, and their bullpen has shown vulnerability, allowing opposing hitters to thrive. Conine, who has a keen eye for pitches and an impressive ability to make solid contact, is primed for a standout performance. With the Marlins looking to build momentum and Conine’s recent form, betting on him to notch over 0.5 hits, runs, or RBIs feels like a smart play. Expect him to capitalize on any mistakes, making this a compelling opportunity for bettors.

Luis Arraez (MIN) Under 1.5 Hits (-233)

As the Twins host the Phillies, all eyes will be on Luis Arraez, but betting on him to go under 1.5 hits might just be the way to play this matchup. Arraez has been a solid hitter this season, yet he faces a Phillies pitching staff that’s been sharp lately, particularly in limiting contact. The blend of the Phillies’ strikeout prowess and the Twins' recent struggles at the plate makes for a tricky situation for Arraez. In his last few games, Arraez has struggled to find gaps against top-tier pitchers, and with the current line set at 1.5, we see a real opportunity here. The underlying numbers suggest he's expected to average just 0.54 hits per game, which aligns well with the trend of the Phillies limiting opposing hitters. With a 69.9% implied probability on the under, it seems the smart play is to take a seat and watch this one unfold.

That is the whole read. Every leg above is our own number against the price on the board at the time we wrote this, and the price can move before you get on. Bet what you can afford to lose. If betting stops being fun, take a break.
