The model predicts a narrow win for the Braves, with a score of 3.8 to 3.5, but San Diego is expected to cover the run line in nearly 70% of simulations.

Houston will have ace Framber Valdez on the mound, boasting a 3.06 ERA over the last three seasons.
The Mets will counter with Clay Holmes, who hasn’t started a game since 2018.

Other Notable Games
Angels vs. White Sox
The White Sox are coming off a historically bad season, finishing with an MLB-worst 41-121 record. Their win total of 53.5 for this season is the lowest in over 35 years.
The team had the lowest batting average and highest ERA last season, and while they have made some improvements, there’s still a long way to go.
The Angels, on the other hand, have Mike Trout, who, despite recent injury troubles, is healthy to start the season and had the second-highest home run percentage of his career in 2024.
The model predicts a win for the Angels, with a score of 5.3 to 4.4, and they are favored to win on the money line in almost 60% of simulations.
Giants vs. Reds
Giants’ starter Logan Webb has a strong track record against current Reds hitters, holding them to a .225 average.
Conversely, Reds’ starter Hunter Greene has limited current Giants batters to a .133 average.
Greene had a breakout season in 2024, finishing second among all NL pitchers in WAR (6.2).
Despite the Giants’ struggles in batting average and OPS last season, they remain favored to win this matchup.
The model forecasts a close game with the Giants winning 4.7 to 4.3, but backs the Reds on the run line as Cincinnati covers well over 60% of the time.
Mariners vs. Athletics
The Athletics struggled to average over 4.0 runs per game last season, and the model predicts they will fall short of even that modest mark.
With Logan Gilbert on the mound for Seattle, the Athletics’ current roster has a dismal .090 average against him.
Gilbert, a 2024 All-Star, has more strikeouts (28) than total bases allowed (20) against the Athletics.
The model is highly confident in a Mariners win, with a projected score of 4.6 to 3.3, and bet365 Sportsbook offers the best price on this bet.
Conclusion
Opening Day 2025 promises to be an exciting start to the MLB season, with several key matchups and intriguing storylines.
From the Braves’ narrow edge over the Padres to the Astros’ continued dominance over the Mets, and the Angels’ expected win over the struggling White Sox, fans have a lot to look forward to.
