The Texas Rangers will try to take a 3-1 series lead over the Arizona Diamondbacks tonight in Game 4 of the 2023 World Series. The Rangers defeated the Diamondbacks 3-0 in Game 3 on Monday night, thanks to their bullpen and defense.

Texas will send southpaw Andrew Heaney (0-0, 6.00 ERA), while the Diamondbacks will go with reliever Joe Mantiply as an opener (2-0, 4.26 ERA). Jon Gray was supposed to be the starter for Game 4, but he pitched three innings of relief in Game 3. Meanwhile, Arizona will be looking for a clean first inning from Manitply before turning it over to the bullpen.

Can the Rangers stay perfect on the road in the postseason? Or will the Diamondbacks tie up the series at 2-2? Below, we’ll break down Game 4 of the 2023 World Series and provide our prediction using odds courtesy of FanDuel Sportsbook.

Rangers vs. Diamondbacks probable pitchers for World Series Game 4

  • Texas: Andrew Heaney (lefty) – 10-6, 4.51 ERA
  • Arizona: Joe Mantiply (lefty) – 2-2, 4.62 ERA

Heaney has made five appearances in the postseason, which includes two starts against the Orioles and Astros. The southpaw has given up seven hits, four earned runs, and two walks in six innings.

As for Mantiply, he has a 4.26 ERA in this year’s playoffs but has only allowed five hits and four earned across eight appearances.

Rangers vs. Diamondbacks Prediction and Pick

Unlike the first two games, where we saw 21 runs scored, offense was at a premium in Game 3 as both teams combined for four runs. The Rangers were 1-for-5 with runners in scoring position, while the Diamondbacks were 2-for-7.

Therefore, it will be interesting to see how the southpaws can neutralize the top of each team’s batting order in Game 4. Through three games, Corbin Carroll is 3-for-13 with four RBIs, while Ketel Marte is also 3-for-13 with four RBIs. As for the Rangers, Marcus Semien is 3-for-14 with an RBI, but Corey Seager is 2-for-12 with two home runs.

Texas will be looking for Seager to carry them to a win after Adolis Garcia hurt his oblique on Monday night. If Garcia cannot play tonight, it will be a massive loss as he’s been one of the best players in the postseason (.323 with eight home runs and 22 RBI). 

It’s hard to cap bullpen games because you don’t know which team necessarily has the edge. In the two starts that Heaney made in the postseason, he went 3.2 innings against Baltimore and one inning against the Astros. Nonetheless, both teams had to use some of their best relievers in Game 3, but best believe all will be ready for a pivotal Game 4 that could decide how the rest of this series plays out.

With the moneyline at -108 for both teams, the best bet is the UNDER 9.5 runs (-120). I don’t believe we will see a slugfest tonight in Chase Field, but both teams will scratch across a few runs against these relievers.
