Diamondbacks vs. Rangers Prediction, Picks & Odds: World Series Game 1
On Friday night, the Texas Rangers will host the Arizona Diamondbacks in a surprising World Series matchup that few expected. We will now provide our prediction for Game 1 of the World Series between the Diamondbacks and Rangers based on the most favorable MLB odds available.
Looking for a sense of just how improbable this World Series pairing was? BetMGM set preseason odds of +175000 for the Rangers and Diamondbacks to face off in the championship.
The Diamondbacks are making their second appearance in the World Series, having previously won in 2001. They have managed to win every series so far without the benefit of home-field advantage, defeating the Milwaukee Brewers, Los Angeles Dodgers, and Philadelphia Phillies. Despite losing 110 games in 2021, Arizona has made history by becoming the first team to reach the World Series within two years of such a dismal season.
Similar to Arizona, Texas also achieved three consecutive series wins without playing at home against the Tampa Bay Rays, Baltimore Orioles, and Houston Astros. The Rangers are among six MLB teams that have never won a World Series, falling short in their two appearances in 2010 and 2011.
Below is our top prediction for Game 1 of the World Series between the Diamondbacks and Rangers, based on odds from our trusted MLB betting sites. Our confidence level is rated on a scale of 1 to 5 stars.
Diamondbacks vs. Rangers prediction: World Series Game 1
Under 8 (+102 via DraftKings) ⭐⭐⭐⭐
Both Game 1 pitchers, Zac Gallen and Nathan Eovaldi, are well-rested as they were not utilized in their teams’ all-hands-on-deck strategies during Game 7 of the LCS.
Arizona’s prospects for Game 1 are not looking good, especially given Gallen’s struggles in both of his starts against Philadelphia. In the NLCS, Gallen gave up nine earned runs and five home runs in just 11 innings. This is concerning considering the Rangers, who have a much higher OPS at Globe Life Field compared to on the road, hit significantly more home runs in their home park.
Despite Gallen’s impressive performances against the Rangers, particularly holding Adolis Garcia hitless in five at-bats, the importance of Garcia’s offensive contributions cannot be overlooked. Garcia’s outstanding postseason performance has been crucial for Texas, especially considering leadoff man Marcus Semien’s struggles at the plate. If Garcia is unable to maintain his stellar efforts, the team’s offensive capabilities will be significantly diminished.
Throughout the playoffs, Eovaldi has proven himself to be one of the most impressive postseason pitchers of late. Winning all four starts, he has maintained a 2.42 ERA, 0.96 WHIP, and 9.7 K/9. The consistency of quality starts in each postseason game highlights the trust manager Bruce Bochy has in Eovaldi, especially in a time when starting pitchers are often pulled from games earlier than before.
Eovaldi’s performance in the playoffs has improved with a rating of 96 in stuff, 106 in location, and 105 in pitching, compared to his regular season splits of 101, 100, and 98. This shows that he is stepping up and delivering his best work when it matters most in the postseason.
We are confident in making the Under a four-star play for the upcoming game. In the postseason, four teams who had two or more days off only scored a total of 10 runs in their first game back after the long break. This trend suggests that the extra time between games tends to cool off the bats.

DraftKings (+102)
| DraftKings | FanDuel | BetMGM | Caesars | bet365 |
|---|---|---|---|---|
| 8 | 8 | 8 | 8 | 8 |
| Over (-122)/ Under (+102) | Over (-108)/ Under (-112) | Over (-115)/ Under (-105) | Over (-115)/ Under (-105) | Over (-115)/ Under (-105) |
All of our top sports betting apps have a consensus total of 8.0 runs, but there is significant variation in juice on each side of the total. DraftKings is the only platform offering plus-money for the Under, while FanDuel has a reverse split and charges more than the standard -110 vig to bet on that side.
At 7.5, this would not be a recommended bet. However, since four out of our top five sportsbooks have the Over bet heavily favored, it is more probable that the line will rise to 8.5 rather than drop to 7.5.
