The Major League Baseball season is winding down, and for some high-profile players and one particular manager, it probably feels like the longest season of their careers. So who was this year's biggest disappointment?

This past off-season, the two biggest free agents were Albert Pujols and Jose Reyes, both of whom left their longtime teams for greener pastures, but they only found the same grass.

Reyes had hoped for a shot at the World Series with the newly named Miami Marlins, but it looks like they'll finish up in last place.

Albert Pujols was called greedy in the off-season after leaving the St. Louis Cardinals, the only team he had ever played for, for the Angels and a bit more money. Now it looks like St. Louis will get back into the playoffs, while the Angels sit it out.

Then there are the Boston Red Sox. Many thought that manager Bobby Valentine would come in to correct the problems that led to the team's historic collapse at the end of the 2011 season. Instead, he appears to have made things worse.
