The Rookies Worth Knowing By Name

JUNE 20, 2026

The first-year players worth watching.

It's rookie day, and the class has a clear headliner. Munetaka Murakami is hitting like a veteran star for the White Sox, while a handful of younger names are starting to climb. Some are future fixtures; some are riding a good few weeks.

The rookie class

Top first-year players, hitters by OPS (minimum real playing time).

Murakami leads the first-year bats at a .938 OPS with 20 homers, the rare rookie already running with the elite hitters. San Francisco's Bryce Eldridge is right behind at .931, and on the mound the Athletics' Gage Jump tops the rookie arms with a 2.37 ERA.

Rookies breaking out

Rookies with the biggest OPS jump this week.

The Mets' A.J. Ewing made the biggest jump this week, up 62 points to a .719 OPS. The Athletics' Henry Bolte keeps trending up too, adding 44 points to reach .825 and pulling double duty as one of the better rookie bats overall.
