If every World Series game could be described as a punctuation mark, Game 3 would have been 10 exclamation marks. 

The Milwaukee Brewers hung 10 runs on the Tampa Bay Rays on Monday night en route to one of the largest win margins in recent World Series history. They’ve made quick work of a Rays team that looked formidable against the Yankees and Guardians, and they’re nine innings away from their franchise’s first World Series. They would be fine to lose tonight with a chance to win in front of their home crowd available for Game 5, but Milwaukee’s been so pedal-to-the-metal that a sweep tonight wouldn’t even be a surprise.

Griffin Jax will take the mound tonight in a must-win Game 4 at Tropicana Field. He’s coming off a three-run, five-hit outing against the Cleveland Guardians through four innings in Game 3 of the ALCS. This isn’t a great spot for him to have a recovery game against a group of hitters as on fire as these Brewers are. Tampa can’t let Jax mess around too much in this game; this could be a quick appearance for him if trouble arises within the first few innings.

Rays vs. Brewers World Series Game 4 value plays

This stellar team is one game away from lifting their franchise’s first-ever World Series, and they shouldn’t take much longer. In Game 3, Milwaukee shelled Freddy Peralta for five earned runs off seven hits and three walks. He had been one of the most consistent arms in this MLB postseason. They were able to score eight of their 10 total runs in the fifth inning alone, which is an incredible feat.

Sure, Milwaukee may want to win their first title in front of their home crowd, but a sweep wouldn’t exactly be starkly opposed by their fans. Take the Brew Crew to close out the series tonight.

Rays vs. Brewers World Series Game 4 player props

Tampa is playing with the utmost sense of desperation down 3-0 in the World Series. If Milwaukee strings together an early-inning rally, manager Kevin Cash won’t hesitate to send in another pitcher. This play requires Jax to finish the fourth inning, and that could be cutting it close. He hasn’t been reliable this postseason, and he doesn’t have much of a leg to stand on if the Brewers can put the bat on the ball early.

Milwaukee’s catcher looks to be in a two-horse race with Jackson Chourio to win World Series MVP; a great performance to close out the series would guarantee it for Contreras. He’s been the best hitter of the World Series with a .615 average, along with three RBIs and a run. In the past, he’s gone 2-for-4 off of Jax, and his current form shouldn’t give much of a reason to shy away from success tonight. Contreras has hit this 1.5 H+R+R line in every World Series game; take him to replicate the good showings.
