The runner at second base, Gonzalez, made it home for a headfirst slide in 7.32 seconds, according to Statcast™, his second-fasted time from second to home this season. But he was called out by plate umpire Angel Hernandez after an 89.9 mph throw from Heyward. Heyward had an assist earlier this year tracked at 98.9 mph, so it was far from his best throw this season.
Gonzalez immediately raised his arms and signaled to the Dodgers dugout that the call should be challenged. Manager Dave Roberts obliged, and the Dodger Stadium faithful cheered when one angle of a scoreboard replay appeared to show Gonzalez getting his fingertips on home plate before catcher Willson Contreras' tag.
But the totality of the evidence was not convincing enough to overturn the call on the field. According to the official ruling: "After viewing all relevant angles, the Replay Official could not definitively determine that the runner's hand contacted home plate prior to the fielder applying the tag." The call stood, and Gonzalez was out.
The teams moved to the third inning locked in a scoreless tie before the Cubs' offense broke out in the fourth en route to a 10-2 victory to even the best-of-seven matchup.
