2K Sports has shipped two PSP games to retail today, MLB 2K6 and World Poker Tour.

MLB 2K6 for the PSP includes most of the features from the console versions, including the Swing Stick control, World Baseball Classic Mode and commentary from Jon Miller and Joe Morgan. It also has a PSP-exclusive Home Run Derby Mode, a tag team-style hitting match, and online play (both ad-hoc and infrastructure).

World Poker Tour, meanwhile, includes prominent poker venues, comprehensive player customization, deep AI and online play. As you'd expect, it's based on the popular TV series.
