AL Wild Card Series: Red Sox vs. Yankees Odds & Pick

TUE, WED, THU at 8 p.m. ET (NBC, Peacock)

SERIES FAVORITE: New York Yankees -146 vs Boston Red Sox +122 (FanDuel)

A familiar matchup is on tap in the American League with these two bitter rivals. The Red Sox and Yankees have played 27 games against each other in the postseason. The Yankees hold a narrow 14-13 edge. Each team has won three postseason series against the other. Most recently, last fall, the Yanks beat Boston 2 games to 1 in this same Wild Card round.

On paper, it seems the Yankees scored more runs, walked more, and had a lower ERA than the Red Sox. But, Boston had a more efficient pitching staff in 2026: 3.64 FIP compared to 3.71 for the Yankees. Boston also walked fewer batters, though the Yankees allowed fewer baserunners overall.

Both pitching staffs were among the best in baseball this season. This is not your dad's Red Sox/Yankees "swing for the fences until you win" matchup. Both teams tamp down opponent scoring.

The Red Sox have actually had more men on base this season. But they scored 52 fewer runs than the Yankees. That's because the Yankees had 61 more home runs. New York left the fewest runners on base in MLB, while the Red Sox ranked 8th in runners left on base. In many ways, the Yankees are (again) a one-trick offense: hope for a walk and a two-run homer.

Boston is not as healthy as its opponent. The team placed utility man Mickey Gasper and relief pitcher Tyron Guerrero on the Injury List at the end of the regular season. The Yankees have the biggest injury news: former MVP Aaron Judge is still not cleared to play, suffering from a calf strain.

Even without Judge, the Yankees should have the power to score enough against the Red Sox. But this will likely be a low-scoring, three-game series. Last season, BOS vs. NYY resulted in only 15 runs in the three-game Wild Card series.

Series Prediction: Yankees 2 games to 1

Game 1 may be a great pitching duel. In two starts against the Yankees, Boston ace Sonny Gray had a 1.98 ERA. His counterpart, Cam Schlitter had a 0.74 ERA in four starts against Boston AND he pitched 8 scoreless frames against the Red Sox in the playoffs last year, striking out 12. I like Schlittler to be great on the big stage again, and give the Yankees a leg up in a short series.

AL Wild Card Series: White Sox vs. Astros Odds & Pick

TUE, WED, THU at 5 p.m. ET (Peacock, NBC Sports Network)

SERIES FAVORITE: Houston Astros -152 vs Chicago White Sox +126 (DraftKings)

Call this the Mediocre Bowl. The 81-win Astros get to host the 84-win White Sox in a series of teams that sort of scraped their way into the playoffs by the tips of their fingernails. Both teams rely too much on home runs, and can't pitch very well.

The White Sox improved their home run total by 45, and they play in a terribly weak division. That explains why this team is in the postseason. Otherwise, the ChiSox have a mediocre pitching staff and mediocre defense (-15 Fielding Runs).

But here's the good news for White Sox fans: the Astros are even more "average-y." Houston's bullpen ERA is 17th in MLB, and the defense came in at -8 Fielding Runs. The Houston pitching staff was dreadful: 24th in MLB at nearly 4.5 runs per game. What happened to the Astros pitching, which was once a strength? Apparently they forgot how to throw pitches over the plate: Houston ranked 2nd in MLB with roughly 4 walks issued per game.

Walks + home runs equal trouble. The Astros pitching staff will need to reduce bases on balls against a powerhouse ChiSox lineup led by Munetaka Murakami (35 HR), Miguel Vargas (33 HR), and Colson Montgomery (31 HR). This is only the fourth time, and first since 2008, that the White Sox have had as many as three 30-HR hitters.

Houston's hopes rest with likely AL MVP Yordan Alvarez, who won his first batting title, finished second in HR and RBI, and led the league in walks, OBP, SLG, and OPS. The Astros led the league in HR, thanks in large part to their home ballpark.

Series Prediction: White Sox 2 games to 1

The Astros are 38-36 since July 1. They were 27-34 before June 1. The team had a 16-11 record for four weeks in June. That's basically all that elevated them to first place. This is a team that hasn't played impressive baseball at any point of the season. Ultimately, it's not that I believe so much in the White Sox, it's that I don't like Houston's penchant for allowing walks and runs.
