MLB is essentially a port of the PS2 version of the same game. With the exception of a few minor details, such as batter walk-ups and celebrations, the presentation makes its way to the PSP relatively intact. Player models are fairly well detailed and animate smoothly. Most of the flashier animations like diving catches and knee catches are around. Player uniforms even get dirty as the game progresses, which is a nice touch. Even stadium details like scoreboards and ads are around. All-in-all, this is about as complete a port as fans could hope for.
The last thing I was expecting to make the jump to the PSP version was commentary, something the other sports games haven’t had. Matt Vasgersian and Dave Cambell handle play-by-play duties and sound really good. While it isn't as verbose as the PS2 version, the inclusion of commentary is still impressive, if a bit off at times. It doesn’t happen often, but Dave sometimes says something that has little to do with what’s going on, such as saying a player is in a slump after a strikeout. Other ballpark sounds, like in-field calls, crowd noise, and announcements, fill in any dead time between calls.
