Addison Russell is having himself a night in Game 6 of the World Series for the Chicago Cubs.

The young shortstop has six RBIs through three innings, including a grand slam off Cleveland Indians reliever Dan Otero that gave the Chicago Cubs a commanding 7-0 lead.

Aided by an Indians misplay in the outfield, Russell hit a two-run double off starter Josh Tomlin in the first to help the Cubs jump in front 3-0. Then he drove Otero’s third pitch into the center-field seats for the first World Series grand slam since Paul Konerko connected for the Chicago White Sox in 2005 (Game 2). It was the first grand slam by a Cubs player in the World Series and the first given up by an Indians pitcher.

Who exactly is Addison Russell, Chicago Cubs shortstop/second baseman?

Russell, 22, is from Pace, Florida. Baseball America named Russell its third-best prospect in professional baseball in 2015. That’s the same year Russell made his pro debut.

He is 6-foot, 200 pounds.

The Cubs are looking to become the first team since the 1979 Baltimore Orioles to rally from a 3-1 Series deficit by winning the final two games on the road.
