Rather than ban home plate collisions outright, Major League Baseball and its players adopted a rule limiting them this season.FILE - In this May 25, 2011 file photo, Florida Marlins' Scott Cousins, top, collides with San Francisco Giants catcher Buster Posey (28) on a fly ball from Emilio Bonifacio during the 12th inning of a baseball game in San Francisco. Cousins was safe for the go ahead run. A new rule, 7.13, was adopted by MLB and the players' association on a one-year experimental basis, the sides said Monday, Feb. 24, 2014. The umpire crew chief can use the new video-review system to determine whether the rule was violated.
