MLB 2025: Second-half preview, rankings, playoff odds - ESPN

Some things about the 2025 MLB season have been predictable: the Los Angeles Dodgers having one of the best records in the majors, Aaron Judge having another MVP-caliber season, and Paul Skenes continuing to dominate as one of baseball's best pitchers.

As always, though, there have been a number of surprises, too — both good and bad. The Baltimore Orioles and Atlanta Braves have had incredibly disappointing campaigns, with both clubs near the bottom of their respective leagues. Juan Soto began his tenure with the New York Mets off to a slow start before heating up and riding that momentum into the All-Star break. Nobody thought the Colorado Rockies would be good this year — but nobody thought they'd be this bad, on pace to break the single-season loss record set by the Chicago White Sox just last season.

The second half of the season is sure to bring more excitement, with a battle at the top for best record between the Dodgers, Detroit Tigers and Chicago Cubs. A number of division races are also close, as the Cubs are up only a game on the Milwaukee Brewers in the NL Central, the Mets are just a half-game behind the Philadelphia Phillies in the NL East and the Toronto Blue Jays, after a red-hot streak to end the first half, lead the New York Yankees by two games. And the wild-card races could go down to the wire, with six teams in the American League within five games of the final wild card and four in the National League within six games of the final spot.

How will all of these teams perform in the second half? Who will dominate in the homestretch? And what does your club have to play for?
