The biggest play of last night’s Game Six was a defensive one, but not in a positive manner: a miscommunication between Tyler Naquin in center field and Lonnie Chisenhall in right failed to result in a catch. Two runs scored for Chicago, and the Cubs took a 3-0 lead in just the first inning. The biggest strategic decision, meanwhile, concerned the use of Aroldis Chapman by Joe Maddon, as Chicago’s manager went to his closer in the seventh inning of a 7-2 game. It’s hard to discount the the implications either of Cleveland’s defensive misplay or Maddon’s bullpen management on the outcome of this World Series.
However, Game Six of the World Series also featured an unimportant strategic decision that facilitated some unimportant defensive plays. Even though he scored no runs and recorded zero hits, the decision to start Jason Heyward was likely worth several runs for the Cubs. And even if those runs didn’t ultimately represent the difference between a win and a loss, Heyward’s presence in the game nevertheless revealed how an offensively struggling but defensively forceful player can impact a result.
In the fourth inning of last night’s contest, right after Mike Napoli singled in Jason Kipnis to make the game 7-1, the Chicago Cubs possessed a 94.8% chance of victory. The leverage index was a fairly low 0.47, so even a positive result for Cleveland was unlikely to influence the game greatly. Facing Jake Arrieta, Jose Ramirez struck a ball that lands for a hit 56.8% of the time and goes for extra bases 20% of the time.
Here’s the end of that play:
At first glance, the play appears challenging for Heyward but hardly impossible. As mentioned above, batted balls with similar exit velocity and launch angles were caught around 43% of the time. Nearly half, in other words. What that figure doesn’t account for, however, is Heyward’s position at the start of the play relative to the location of the ball in the field. We can go a little further with the Statcast data.
By doing a few calculations, we can determine that, if he were running in a 40-yard dash in this case, Heyward would have recorded a time of roughly 9.9 seconds, which is really slow for a 40-yard dash. Of course, when Jason Heyward hears the ball off the bat, he doesn’t simply get to sprint straight forward in a line. He has no idea in which direction he might have to run — backwards, forwards, left, right. He decides where to run by looking at a small white object that begins its trajectory roughly 300 feet away while also traveling at 98 mph.
We rarely see an outfielder’s first step when watching the game because both our own eyes and also the cameras themsleves are focused on the batter-pitcher matchup. Heyward is very good at making quick decisions, though: the first step on his acrobatic play near the wall in Game Five occurred within 0.17 seconds.
