Jon Metler's expert pick: Nationals moneyline

Price: 45¢ (+122) at Polymarket

If you’re going to beat the Arizona Diamondbacks, it starts with finding a way to slow down Corbin Carroll, who currently leads the National League in fWAR and serves as the engine of their offense.

That’s why I like this matchup for left-hander Foster Griffin and the Washington Nationals. Griffin has been excellent against left-handed hitters this season, holding them to a .178 batting average and a .624 OPS. He also benefits from a familiarity edge, as he has never faced this Diamondbacks lineup before, which is typically an advantage for a starting pitcher.

The Nationals are trading at 45 cents on the moneyline, but I make them much closer to 50 cents in this matchup. With Griffin well-positioned to neutralize Arizona’s biggest offensive threat, I’m willing to back James Wood and the Nationals at this price.

Neil Parker's expert pick: Guardians/Rangers NRFI

Price: 58¢ (-140) at Polymarket

With Texas Rangers right-hander Kumar Rocker pitching a scoreless first inning in three of his past four starts and holding hitters to an overall .159 batting average, I’m anticipating him taking care of a Cleveland Guardians lineup that ranks 26th in wOBA against righties in the opening frame.

Meanwhile, Cleveland southpaw Parker Messick hasn’t allowed a first-inning run all season, holding opposing hitters to a minuscule .371 OPS.

The Rangers are also 28th in wOBA against lefties, and this NRFI hits the break-even mark at -140.

Jason Wilson's expert pick: Rays moneyline

Price: 56¢ (-127) at Polymarket

Tampa Bay Rays righty Drew Rasmussen gives enough of an edge over Miami Marlins opener Ryan Gusto that this is an automatic buy at -127.

Gusto threw 40 pitches on Tuesday and is pitching on two days of rest. Even if he finds some success, he won't be long for this game.

While it's tempting to take the Under 7.5 at +113, I'll grab the visitors to win straight up behind Rasmussen.

The Rays rank Top 10 in wRC+ against right-handers, and Gusto's small sample size of work in 2026 doesn't magically make me forget about his 5.67 ERA and 22nd-percentile xERA, 11th-percentile hard-hit rate, or 14th-percentile average exit velocity from 2025 over 101 2/3 innings. 

I'd happily take the Rays all the way to -150 tonight.
