I love the movie from begining to end. I just thought that he was gonna start to push himself way harder than before. So he can make it back to the major league, but thats not how it happen. Instead sugar was just looking for the fun of the game the whole time and he did.
I also think the movie shows a very powerful impact on how people in the Dominican Republican live. So leaving DR to the United States will be a little bit more for suger since he isnt really used to it.
