Not that I was asked, but I feel like documentaries have covered this a bit better and I have always put forth A PLAYER TO BE NAMED LATER as the best I've seen that has discussed the hard work, dedication, and heartbreak that goes into attempting to summit the Big Leagues. All the old films on baseball are way too romantic, the modern stuff glosses over all of it. MILLION DOLLAR ARM is such a Disney pile of crap, while I enjoyed it for a kids film, those guys were unlikely to become big leaguers (not to say their story isn't worth noting, because it is a good one). The scouting aspect isn't expanded upon in the docu as much as it was it takes to develop talent. I'm waiting for a piece on the Dominican leagues or Japanese leagues. SUGAR gives a glimpse of baseball school and talent searching, but its main focus is on the character with baseball as scenery.
I played throughout high school, faced Spooneybarger who did make it to the big leagues as well as had cousins and teammates that have played college ball, so I've been around a bit. I also follow minor league baseball pretty closely and no film has ever really gotten the intense work and dedication, with the huge reality that there will probably be no payoff, except for what I've seen in documentaries. KNUCKLEBALL is an interesting look at a difficult pitch, not really thrown well by anyone save a select few.
