Addison Russell won't win the National League Rookie of the Year this season (his teammate Kris Bryant will), but he's still had a huge impact on the Cubs.

What's so crazy about that is Russell didn't even move to shortstop full-time until early August and he's only played 56 games (41 complete games) at shortstop this season. That makes his status as the fourth-best defensive shortstop in the game all the more remarkable.

Thanks to his defense, Russell has earned a 3.1 WAR on Baseball Reference and 2.7 WAR on FanGraphs.

He may not with the Rookie of the Year, but the 21-year-old Russell is going to be a very important player for the Cubs for years to come.
