Yadier Molina has 46 career pickoffs (5 in 2012)
Posey has 2 (both in 2012)
Don't even get off the base lol. Molina is a lot of fun to watch. I remember him ending a game in San Diego that was rather comical. Bases were loaded in the bottom of the 9th with 2 outs in a (I think) 5-4 game with the Cardinals leading.
Molina ended the game by picking the guy off on first, and his run meant nothing.
Now posey did pick molina off third in game seven. He was just called safe.
