As the free-agency season comes down to a close, some teams are still looking for that one piece to the puzzle that could push them over the top. Be it pitching, hitting or even defense, some teams out there could find themselves in either the playoffs or the World Series by filling just one need.
Take the New York Yankees, for example. They appeared to be set going into 2012, but trading potential DH Jesus Montero to the Seattle Mariners left them with a gaping void just aching to be filled, and not necessarily through the "revolving door DH" approach.
Likewise, their division rival Boston Red Sox have a great offense, but lack a deep enough pitching rotation to really push forward.
Thus, lets take a look at five teams who are still on the hunt for top talent to put them in contention.
