In the bottom of the third inning, an error on the part of Chicago Cubs’ second baseman Tommy La Stella pulled first baseman Anthony Rizzo off the first base bag, allowing Nationals’ shortstop Trea Turner to score. Ryan Zimmerman, who was on first at the time of the throw, attempted to break for third, where he was thrown out by a few steps.
However, both clubs (the Cubs and Nats) doubted that both calls (Rizzo was off the base, Zimmerman was out at third) were correct.
