World Series Baseball 2K3

World Series Baseball 2K3 is a sports video game developed by Visual Concepts and published by Sega for the PlayStation 2 and Xbox. It is the successor to World Series Baseball 2K2 and the last to carry the World Series Baseball name. It was released in March 2003 prior to the start of the 2003 Major League Baseball season. It was originally developed for the GameCube, but was ultimately canceled. Entertainment Weekly gave the same console version universal acclaim despite the fact that it was canceled months ago.

Reception
The game received "generally favorable reviews" on both platforms, both a few points shy of "universal acclaim", according to the review aggregation website Metacritic.

GameSpot named the Xbox version the best game of March 2003.
