WASHINGTON -- The umpires had a busy night making replay reviews in the Nationals' 10-7 win over the Marlins on Wednesday night.

Twice, they used replay to determine home run calls. And in the eighth inning, an umpire review was used on a play at the plate.

First in line for the reviews was a home run by Miami's Derek Dietrich in the second inning.

Dietrich was in his home run trot when the Marlins second baseman was told to hold up at third base. In the eyes of the umpires, it was unclear if the drive to right-center off Washington's Jordan Zimmermann had actually cleared the wall.

So Dietrich was initially awarded an RBI triple.

Immediately, Miami manager Mike Redmond came out to ask the umpires to double-check. Because it was a question on a home run, an "umpire review" was used, not an official team challenge.

After checking the replay angles, the call was overturned, and Dietrich was awarded a two-run homer.

Christian Yelich, who delivered an RBI single in the inning, also scored.

In the fourth inning, Bryce Harper launched a deep fly ball down the right-field line that landed in the upper deck. The umpires initially called it a home run. However, Redmond returned to the field to have the umps check if the ball had stayed fair.

After another umpire's review, the initial call stood, giving Harper a three-run shot. Adam LaRoche and Ryan Zimmerman came in to score on the home run, Harper's first of the season.

Finally, in the eighth inning, Miami's Garrett Jones doubled off first base, and the ball skipped into the corner in right field. Yelich scored easy, and Giancarlo Stanton tried to score from first base.

Right fielder Jayson Werth's throw went to Anthony Rendon at second base, and Rendon turned and fired home. Catcher Jose Lobaton made the tag on Stanton, who tried to sneak his left hand onto the plate.

It was a close play, and the umpires again took a look to make sure Stanton was indeed out. The call was confirmed.
