If they catch, he should throw nasty 85 MPH breaking balls to 2B/3B to deke the runners. They'd peek to think it was going wide and ease up or run through the bag, just enough to make a YouTube highlight reel or SportCenter's Top 10.

Ironically, a lot of closers are converted catchers since they have cannons for arms and tree trunks for legs. If there's a backup on the roster or their bats are sub-par, the coaching staff will often give them a shot to be a closer. Some examples: Troy Percival, Jason Motte (I played against him when he caught and his arm was legendary), Carlos Marmol, and Kenley Jansen.
