The 2025 Little League World Series is underway, with some of the best young players around the country competing in Williamsport — all with the hopes of eventually making it to the major leagues one day.

And a few of them will make it … as evidenced by all the Little League alumni in Major League Baseball today.

This year’s MLB Little League Classic between the the Seattle Mariners and New York Mets will feature a number of MLB players who have played little league baseball in one way or another, either with local teams in their home countries or with Little League specifically. In fact, Seattle manager Dan Wilson played in the 1981 Little League Baseball World Series with Barrington (Illinois) Little League.

As the Mariners and Mets face off at historic Bowman Field in Williamsport on Aug. 17 — which you can watch on ESPN’s “Sunday Night Baseball” broadcast at 7 p.m. ET — let’s take a look at “then” and “now” photos of notable players on each team that played little league.
