During the eighth inning of Thursday night's Reds-Marlins game (CIN 3, MIA 1), Todd Frazier flew into what was initially called an inning-ending double play with the bases loaded and one out. Giancarlo Stanton caught the soft line drive in right and fired home to get Zack Cozart, who tagged up from third and tried to score. The throw took catcher Jeff Mathis into Cozart's lane, though the throw beat him by several steps. The new home plate collision rule says a catcher is allowed to block the plate as long as he has the ball, which Mathis clearly did before Cozart got there. Furthermore, MLB has said the catcher can be in the lane if the throw takes him there.
