Watch: Diamondbacks Three-Run Homer Ruled a Two-Run Single After Crazy Mistake

Marrero passed a teammate while rounding the bases, making it not count as a home run.

Deven Marrero seemingly hit his first home run for the Diamondbacks until an unusual mistake happened.

As he rounded first base, Marrero ran past teammate Alex Avila while watching the ball go over the wall. What would have been a three-run home run was ruled a two-run single after further review because the hitter cannot pass someone already on base.

Marrero's RBI hit in the fourth inning increased the Diamondbacks' lead to 5–1, instead of the 6–1 score it would've been as a home run, over the NL West rival Dodgers.
