Brian Erni, MetsBlog.com:This is a fun drill to watch, mostly because it’s amusing to see bullpen catchers Dave Racaniello and Eric Langill act as the runners over and over again. But what struck me from a mechanical standpoint was the emphasis on efficiency. Players close the ground between one another as they anticipate a throw with the goal to get the out in just one toss. In fact, a two-throw run down prompted a boo from one of the players. I really enjoyed seeing this up close.
