Dale Murphy once said, “Playing baseball is not real life. It's a fantasy world...It's a dream come true."
Guys continue to play in the MLB for a living, which seems to be an exciting enough opportunity to put a smile on one’s face. However, some just show off their grin that much.
Reasons range from lack of productivity to attitude problems.
Some have reason to frown, but these are the guys that should be smiling a lot more.
