This is a once-in-a-lifetime kind of play. You can't blame the guy for continuing to run.
[Catcher Sean] Murphy popped right up to get the ball. Knowing Carroll possessed elite speed from the left-handed batter's box, Murphy appeared to rush his throw to first baseman Matt Olson, who couldn't make the play.
Carroll saw the ball trickling into the outfield and kicked into a second gear. He busted it around the bases, and eventually ended up on third base as teammate Ketel Marte scored from second base.
Would that Murphy's throw had been a little more wild and this speed demon might have actually scored a run on a strikeout!
