It was a nice idea. But not put together well.
The sheer stupidity of a baseball player in Mexico (one of the most heavily scouted areas on the planet) being able to throw a 100 mile per hour fastball and hit a 600 foot long home run and NOT be discovered is stupid.
And I hate Brendan Fraser. I absolutley hate Brendan Fraser.
Albert Brooks is decent, because of his voice work in "Finding Nemo".
Also, cameo appearences of MLB players (Bret Saberhagen of the Royals, Keith Hernandez of the Mets and Ozzie Smith of the Cardinals) are cool.
Still a very poor movie.
