Jon Metler's expert pick: Dodgers moneyline

Price: 60¢ (-150) at Polymarket

Roki Sasaki may have stumbled out of the gate this season, but over the last 30 days, he's looked every bit like the ace the Los Angeles Dodgers expected. During that stretch, he's posted a 10.73 K/9, a 1.48 ERA, and a 2.29 xFIP, establishing himself as one of the most dominant starters in baseball.

At first glance, Chicago White Sox southpaw Anthony Kay appears capable of creating matchup problems for Los Angeles because of the number of left-handed bats in the Dodgers' lineup. However, this isn't a typical lineup when it comes to platoon splits. 

Freddie Freeman has spent his entire career producing against left-handed pitching at nearly the same level as he does against righties, and Kay's sweeping slider isn't nearly as effective against hitters like Kyle Tucker, whose flat swing path matches up well against that pitch shape.

 Los Angeles deserves to be a bigger favorite here, and I make the Dodgers closer to 63 cents in this matchup.

Neil Parker's expert pick: Marlins/Pirates NRFI

Price: 52¢ (-109) at Polymarket

Both Miami Marlins starter Sandy Alcantara and Pittsburgh Pirates right-hander Braxton Ashcraft have been sensational in this market this season, combining to pitch 23 scoreless opening frames across 27 starts.

Additionally, Alcantara’s first-inning numbers (5.14 ERA with a .758 OPS allowed) are skewed because all eight runs he’s surrendered came across just three games.

Ashcraft, meanwhile, checks in with an absolutely elite .169 batting average and .414 OPS allowed in the opening frame across his 21 career starts.

Joe Osborne's expert pick: Brewers -1.5

Price: 53¢ (-110) at Polymarket

Jacob Misiorowski is on an insane tear, allowing just one earned run across his last seven starts and helping the Milwaukee Brewers cover the run line in six of those outings.

The Philadelphia Phillies counter with Andrew Painter, whose 6.21 ERA reflects a difficult season that has included several rough road starts. Meanwhile, Milwaukee's offense is firing on all cylinders, leading MLB in both runs scored and OPS over the past week.

Add in the Brewers' elite offensive production at home and Philadelphia's struggles on the road, and Milwaukee is well-positioned to win by multiple runs tonight.
