Catcher: Buster Posey (2009-present)
Chances are, the San Francisco Giants will move Buster Posey out from behind the plate in the next few years. In the meantime, he has cemented his place in team history.
Posey made his mark felt almost immediately, as he finished 11th in the National League MVP vote while winning the Rookie of the Year award in 2010. That season, he produced a .305/.357/.505 batting line, hitting 18 homers and 23 doubles while hinting at greater things to come. Unfortunately, he was injured the following year when Scott Cousins bowled him over at home plate. That led to the banning of all collisions at home.
Once healthy, Posey again regained his superstar status. A four time All Star and the 2012 MVP, Posey has put together a career .307/.373/.476 batting line, hitting 116 home runs and 190 doubles. He led the NL with a .336 batting average in 2012, and has hit 20 or more homers three times.
The one question with how far Posey will pull ahead in regards to the all time catcher rankings is whether or not the Giants take him out from behind the plate. He has been an above average defensive catcher, leading the National League with 15 runs saved and eight double plays in 2016. Posey has certainly performed well behind the plate, but long term concerns may lead to more time at first or even at DH in interleague games.
Buster Posey has cemented himself as one of the best catchers ever to suit up for the San Francisco Giants. Still in the prime of his career, he has an excellent chance to become the first catcher to crack the top twenty WAR list for the franchise.
