If you’re looking to activate your offer by trading your initial $25 on today’s heaviest moneyline favoriteโ€”the Los Angeles Dodgersโ€”a winning ticket would yield a smaller profit than a successful trade on an underdog.

But we don’t just blindly bet the numbers; we look for the underlying value. When evaluating the Mariners-Dodgers clash, Los Angeles holds a distinct offensive advantage. The Dodgers are mashing with a .774 team OPS and a .433 slugging percentage, while Seattle’s lineup lags behind at a .688 OPS and a .379 slugging clip. Factor in the Dodgers’ superior 3.59 team ERA compared to the Mariners’ 3.71, and it is easy to see why LA is a heavy favorite.

Over in the Nationals-Braves contest, Washington actually brings some value to the plate with a slight offensive edge (.774 team OPS vs. Atlanta’s .729). However, Atlanta is catching heavy chalk due to a massive mismatch on the mound. The Braves’ pitching staff boasts a collective 3.70 ERA, drastically outperforming Washington’s vulnerable 4.75 team ERA. We’ve seen time and time again that elite pitching neutralizes decent hitting.

Official Prediction: The true value lies in backing the Braves’ pitching to stifle the Nationals. However, if you want to swing for the fences, taking a flyer on the Mariners’ pitching staff to keep things tight against the Dodgers isn’t the worst way to go for a longshot prediction.
