Second-base umpire Lance Barksdale originally called Andres Torres safe at second base, after Rockies pitcher Jhoulys Chacin fired a pickoff throw and caught Torres straying too far off the bag. Chacin threw to shortstop Jonathan Herrera, who relayed to third baseman Jordan Pacheco as Torres was caught in a rundown and scurried back into second.
But Pacheco caught up to Torres as he neared the base, sliding with him and appearing to tag him on the right leg. After Barksdale initially called Torres safe, third-base umpire Fieldin Culbreth met with Barksdale to overrule the call.
That brought Collins out of the dugout in a rage. He argued with Culbreth, earned his ejection and then argued some more before retiring to the clubhouse.
