While one can definitely argue that Corey Perry, who has a reputation for going to the blue paint, that his stick caught Shesterkin up high, there is absolutely no excuse for these kinds of actions.
Perry received a 2-minute penalty for this, but Shesterkin should have absolutely received one as well for embellishing. Shesterkin throws himself back, flinging his stick in the air like he had just been shot.
The Rangers would score on the ensuing powerplay, definitely should have been a 4-on-4 situation.
