It's an infielder's pay. A good back-hand and then some. Frandsen sort of shrugs at the end of the play.
Incidentally, daughter saw Tyler Clippard catch a BP fly ball reaching around his back catch the ball on his right side. However, Clippard was joking with Drew Storen, who tried the same catch on the next fly ball, and missed. Pretty hard even when there are no runners on base.
