The patch for MLB 2K10 has gone live on the Xbox 360 and the prompt to download will be presented when starting up the game. The most high profile changes that arrive with this patch include the addition of check swings, adjustments to manager AI on pulling pitchers, and fixing of the problem that has been preventing online ranked games from being played. Unfortunately it appears the PS3 version is being neglected as 2K Sports is unwilling to commit to a patch and may be planning to roll the changes seen in this first patch in with a second patch down the line.
