Unpacking Wednesday's Top MLB Bets

The SportsLine Projection Model, renowned for simulating every MLB game 10,000 times, has been on an impressive run. It entered Week 22 of the MLB season with a sizzling 49-31 record on all top-rated MLB picks, and even generated nearly 30 units of profit on home run prop picks in 2025.

For Wednesday, the model and SportsLine experts have locked in several compelling predictions. These include backing the Orioles (+105) to defeat the Yankees, taking the Over 8.5 total runs (-110) in the Marlins vs. Phillies game, and a player prop for Max Scherzer, Blue Jays, Under 15.5 total pitcher outs (-175).

Combining these three picks into a parlay at BetMGM Sportsbook could result in a significant payout of +514, meaning a $100 risk could yield a $514 profit, though odds are subject to change. This offers a thrilling way to engage with the day's best baseball action.

Analyzing the Yankees vs. Orioles Prediction

Despite the Yankees' recent two-game winning streak, their offense has been largely anemic, scoring only seven runs across those victories and a mere two runs in their preceding three losses. Over their last five games, the Yankees are averaging a paltry 1.8 runs per contest, a challenging pace for any team hoping to win regularly.

Adding to their struggles, New York is sending Will Warren to the mound, who has posted a 7.71 ERA in two August starts and recently surrendered five runs in just four innings. Conversely, Baltimore first baseman Pete Alonso arrives in top form, boasting a 10-game hitting streak with five home runs during that span. The Orioles will counter with veteran pitcher Chris Bassitt, who holds a career 3.71 ERA over 12 seasons. The model confidently projects the Orioles to win in 55% of simulations.

Marlins vs. Phillies: Offensive Output Expected

The matchup between the Marlins and Phillies features two former All-Star pitchers, Aaron Nola for Philadelphia and Sandy Alcantara for Miami. However, neither has demonstrated consistent elite performance in recent seasons, with Nola holding a 5.33 ERA this year following a 6.01 ERA last year, and Alcantara registering a 5.36 ERA last year.

While both pitchers have shown some improvement lately, the offensive trends of their respective teams suggest a high-scoring affair. The Phillies have seen the 'Over' hit in three consecutive games and are averaging seven runs per game over their last four contests. Similarly, the Marlins have been productive, averaging 5.7 runs over their last three outings. Given the pitchers' past inconsistencies and the recent offensive surges, the model leans heavily towards the 'Over,' predicting it to hit in 55.7% of simulations.

SportsLine player prop expert Alex Selesnick, known as PropStarz, also shared his reasoning for backing Max Scherzer Under 15.5 total pitcher outs: "This looks like a good spot to fade Max Scherzer against one of the best offenses in the league," Selesnick stated. He added, "Scherzer has been showing his age and routinely finishing Under this line. I'm willing to pay the hefty juice here as this line should be 14.5."
