It was bound to happen once MLB instituted its new rules. A team has won with a walk-off pitch clock violation.
Specifically, the Colorado Rockies defeated the Washington Nationals 8-7 on Saturday because Nationals closer Kyle Finnegan was a second (or two) too late throwing the ball to Rockies third baseman Ryan McMahon with a full count, the bases loaded and the game tied.
Home plate umpire Hunter Wendelstedt called the violation on Finnegan, giving what is known in baseball internet circles as a shrimp: a walk-off walk. McMahon even seemed to think he had struck out because he swung at Finnegan's pitch, but he was getting a Gatorade shower seconds later.
