WASHINGTON -- Nationals manager Matt Williams challenged a call in the third inning against the Cubs during Sunday's 2-1 win for the Nats, and it ended up getting overturned.
Cubs left fielder Ryan Sweeney led off the frame and hit a ground ball to second baseman Anthony Rendon, who made a wide throw to first baseman Adam LaRoche, and Sweeney was ruled safe.
Williams challenged the call, and after review it was overturned. LaRoche had tagged Sweeney before he reached the base.
Cubs manager Rick Renteria challenged a play in the bottom of the eighth inning, but this time, the call would stand after review.
Nationals center fielder Denard Span connected on a line drive to right field and rounded first base to try and stretch the hit into a double. Right fielder Nate Schierholtz fielded and threw to shortstop Starlin Castro, who was covering second, but Span appeared to avoid the tag and slid safely into the base.
Renteria challenged the ruling on the field, and after review, Span remained on second. He later scored the go-ahead run on Ryan Zimmerman's single.
