Phillies vs. Braves Prediction: Sale Sets the Tone

The Phillies vs. Braves opener starts at 2 p.m. ET on NBC. Chris Sale takes the ball for Atlanta after closing the regular season with a 2.16 ERA, a 0.98 WHIP, and 200 strikeouts across 27 starts. Philadelphia counters with Jesus Luzardo as an opener in a bullpen game, with Andrew Painter available behind him. The Phillies offense went ice cold in September, ranking 29th in OPS and runs per game, and Atlanta plays without Lane Thomas because of a left intercostal strain. The Braves sit around 64 cents to win, and the total is 6.5.

Our Pick: Under 6.5 Runs at 49 Cents

White Sox vs. Astros Prediction: Two Bullpen Games in Houston

White Sox vs. Astros follows at 5 p.m. ET on Peacock. Both managers lean on relief arms in Game 1. Houston starts 26-year-old rookie righty AJ Blubaugh, who posted a 3.66 ERA over 96 innings and never worked as an opener during the regular season. Chicago answers with rookie lefty Hagen Smith, the fifth overall pick in 2024, who owns a 1.29 ERA in 28 innings. Blubaugh struggled late, allowing 10 runs in 9 2/3 innings over his final 10 appearances. Yordan Alvarez carries the Astros lineup nearly alone after hitting .316 with 42 homers. The total opened at 8.

Our Pick: Under 8.5 Runs at 53 Cents

Red Sox vs. Yankees Prediction: Schlittler Owns This Matchup

Red Sox vs. Yankees headlines the 8 p.m. ET window on NBC, and Cam Schlittler takes the mound as the 2026 AL Cy Young favorite, backed by an AL-best 1.95 ERA and 239 strikeouts in 193 2/3 innings. He also feasts on Boston: a 0.74 ERA in four starts with 27 strikeouts in 24 1/3 innings. Rookie southpaw Payton Tolle (3.03 ERA, 171 strikeouts) draws the Game 1 assignment for Boston. New York plans to go without Aaron Judge after an injection in his sore right calf. The Yankees sit near 56 cents, and the total is 6.5 runs.

Our Pick: Cam Schlittler 8+ Strikeouts at 45 Cents

Cubs vs. Padres Prediction: Late-Night Runs at Petco

Cubs vs. Padres closes the night at 10 p.m. ET on Peacock. San Diego hands the ball to Michael King after winning 18 of its final 22 games, while Chicago’s plan stays murkier with Kevin Gausman nursing soreness in his non-throwing shoulder. Matthew Boyd draws the start after seven innings of one-run ball against Miami. The Cubs took five of six meetings this season and led baseball at 5.3 runs per game. San Diego sits at 55 cents with a 7.5 total.

Our Pick: Over 6.5 Runs at 59 Cents
