Major League Baseball 2K7 or in short, MLB 2K7, is an MLB licensed baseball simulation video game developed by Kush Games and published by 2K Sports. It is the only 2007 MLB licensed game available for the Xbox 360 and Xbox. It is also available for the PlayStation Portable, the PlayStation 2 and, for the first time, the PlayStation 3, though its competition came in the form of MLB 07: The Show from 989 Sports. The GameCube has been dropped as a plaform, but portable versions for the Nintendo DS and Game Boy Advance will be released. This is the first baseball game for the DS. According to lead developer Ben Brinkman, MLB 2K7 will be skipped as a Wii title; the first game for the Wii will be MLB 2K8[1].MLB 2K7 was officially announced as gold on February 23, 2007, and will be shipped on February 26, arriving in stores on February 27; its previous release date had been advertised as March 5. [2] This was presumably to prevent early adoption of MLB 07: The Show on Sony platforms. However, the Nintendo DS and GBA versions were conspicuously absent from the announcement.[3] The reported release date for those handhelds is March 19, 2007.

A demo was released on Xbox Live Marketplace for Xbox 360 owners on February 26, 2007.[4]
