With Nationals left-hander Gio Gonzalez on the mound, Dee Gordon hit a ground ball to first baseman Adam LaRoche, who threw the ball to Gonzalez, who swiped at Gordon as the Dodgers' second baseman reached the base.
First-base umpire Ted Barrett ruled that Gordan was safe, and Williams wanted the play to be looked at on replay. After review, the call was overturned and Williams was able to keep his challenge after the ruling.
Four innings later, there was a crew chief review.
Nationals first baseman Kevin Frandsen hit a ground-ball to third baseman Juan Uribe, who threw out Anthony Rendon at the plate. The umpires initiated a crew chief review to determine a potential violation on the part of catcher A.J. Ellis. After review, the replay official ruled that there wasn't any violation of Collision Rule 7.13. Rendon was out and the call was confirmed.
In the eighth, Wilson Ramos hit into a double play, but Williams claimed that Dodgers first baseman Adrian Gonzalez was off the bag and Ramos was safe. After review, the ruling on the field was confirmed and Ramos was out.
