The Rangers swept the season series against the Bruins for the second consecutive year.
Michael Nylander and Jaromir Jagr assisted on Pock's goal and also scored in the shootout. The Rangers won for the ninth time in 13 games to hold onto the seventh spot in the Eastern Conference playoff race.
Marc Savard scored for the Bruins in the second period, and that was the game's only goal until Jagr surprised Boston defenceman Zdeno Chara in the corner and forced a turnover. Pock picked up the puck and made a wrist shot from the left circle that got by Joey MacDonald on the stick side, spoiling the rookie's bid for his first career shutout.
MacDonald stopped 35 shots just a week after he was called in to relieve Tim Thomas against the Rangers and allowed four goals on 11 shots before Thomas had to come back in to finish the game. Boston lost that game 7-0 to start a four-game losing streak.
