eBaseball™: PRO SPIRIT on Steam
store.steampowered.com
Experience authentic baseball with players from around the world. Feel the arc of every hit, the intensity behind each play, and the roar of the crowd surrounding the stadium. With stunning presentation, the game captures the true intensity of real baseball.

This is pretty huge because for the past decade or so, there has only been one simulation baseball game on the market and it was made by San Diego Studios and Playstation.
