This ballpark has had its share of crazy nights. Put this one near the top of the list. Ryan McMahon’s based-loaded walk, which ended with a pitch-clock violation, completed a two-run rally in the bottom of the ninth to deliver the Colorado Rockies an 8-7 victory against the Washington Nationals in front of 34,509 at Coors Field. It is the first walk-off win via the rule in MLB history.
