MLB Experts Predict Winners of All Four Wild Card Series

October opens Tuesday with four Wild Card Series, eight clubs, and no room for a slow start. The Phillies visit the Braves at Truist Park first, followed by White Sox-Astros in Houston, Red Sox-Yankees in the Bronx, and Cubs-Padres under the lights in San Diego.

Houston leans on October mileage

The Astros drew the nod over the White Sox in a close call, largely because Houston has spent much of the past decade playing meaningful October baseball. This is the club’s ninth postseason trip in 10 years, with two World Series championships in that stretch. Yordan Alvarez is in the American League MVP conversation, Jose Altuve brings a long October résumé, and Jeremy Peña adds another familiar postseason face.

Chicago arrives with a different kind of momentum. The White Sox lost 121 games just two seasons ago and are back in the field for the first time in five years. Munetaka Murakami and Miguel Vargas supply middle-of-the-order thunder for a younger club with little to lose.

Houston also carries Josh Hader at the back of the bullpen and home-field advantage. Still, there is a crack in the door: the Astros reached the bracket without finishing above .500, the first postseason entrant ever to do so. One forecast sees the White Sox’s energy and talent enough to spring a surprise, but the prevailing expectation is that Houston’s veteran core survives a three-game fight.

Yankees have the arms, while Judge remains the question

The Red Sox-Yankees rivalry arrives with a familiar edge, but the pitching matchup is the center of this one. New York can line up American League Cy Young favorite Cam Schlittler alongside Max Fried and Gerrit Cole, a rotation advantage that could decide a short series.

Boston has stumbled offensively down the stretch, producing just 71 runs in September, fewest in the majors. Since its surge ended Aug. 7, the Red Sox have gone 23-24. That is a cold finish to carry into Yankee Stadium.

New York’s concern is Aaron Judge. The three-time AL MVP returned to the injured list earlier this month because of a right calf strain, leaving his availability uncertain. The Yankees’ lineup often follows Judge’s lead, and Boston has a counterargument: its collection of left-handed pitchers could expose a New York offense that has had trouble against lefties.

Even so, the Yankees’ starter advantage stands out. Schlittler, particularly, is viewed as the kind of pitcher who can take control of a postseason game when the pressure climbs.

Atlanta sees an opening in Philadelphia’s rotation

The Braves bring a deeper lineup and a cleaner pitching setup into their home series against the Phillies. Ronald Acuña Jr., the former MVP and five-time All-Star, headlines a seasoned group. Matt Olson hit 41 homers and posted a .502 slugging percentage, his strongest power season since 2023. Catcher Drake Baldwin followed his 2025 National League Rookie of the Year season with 25 homers, while Michael Harris II bounced back at the plate after two ordinary years.

Philadelphia had to use Zack Wheeler on Sunday to clinch a playoff berth on the final day of the regular season. Jesús Luzardo and Cristopher Sánchez are scheduled for the first two games, but Wheeler’s short-rest availability is unclear. Luzardo has thrown only four big league pitches since going down with inflammation in his left shoulder.

The Phillies also needed all four of their top starters to secure the berth, including one pitcher coming off the injured list for a one-inning appearance in Game 162. That workload has raised doubts about whether Philadelphia can get its usual production from Wheeler, Luzardo and Sánchez. The counterpoint is simple: even with a compressed schedule, the Phillies still possess formidable starting pitching.

Atlanta’s home field and its chance to answer postseason losses in 2022 and 2023 give this matchup an added charge.

Padres trust the bullpen at Petco Park

San Diego closed hard, winning 18 of its final 22 games to claim the National League’s top Wild Card position. The Padres went 51-30 at Petco Park, where a loud October crowd can make the late innings feel closer than they are.

The biggest San Diego edge is the relief corps led by Mason Miller. In a best-of-three setting, that bullpen can turn a six-inning game into a short walk to the clubhouse. Miller did show some unexpected shakiness over the final weeks of the season, though, and Chicago has enough offense to test every arm.

The Cubs scored more runs than anyone this year, with National League MVP contender Pete Crow-Armstrong at the center of the attack. His power-speed combination can change an inning, a game or a series in a hurry. Alex Bregman’s recent hot bat gives Chicago another important threat.

For the Padres, the assignment is clear: contain Crow-Armstrong, hand a lead to the bullpen, and let Petco Park carry the noise through the final outs.
