Baseball returns to the Olympic program for the first time in 13 years, but the first U.S. Olympic baseball team since 2008 includes a player with Olympic experience.
Eddy Alvarez, a 2014 Winter Olympic silver medalist in short track speed skating, is set to become the 11th American to compete in both the Summer and Winter Games.
Alvarez, an infielder in the Miami Marlins system, is a headliner on a 24-man roster made up mostly of minor leaguers.
The roster is split with 12 pitchers and 12 position players.
Past MLB All-Stars are also headed to Tokyo: infielder Todd Frazier and pitchers Edwin Jackson, Scott Kazmir and David Robertson.
