Russell will make his Major League debut at the age of 21, making him the youngest player in the National League.
The Cubs acquired Russell in a blockbuster trade last season that sent pitchers Jeff Samardzija and Jason Hammel to Oakland in exchange for Russell, outfielder Bill McKinney and pitcher Dan Straily. Hammel is now back on the Cubs' roster.
Oakland drafted Russell with the 11th overall pick in the 2012 MLB draft. Russell will play second base for the time being, but Chicago has plans for him to eventually take over at shortstop, according to Ken Rosenthal.
Russell has hit .314 with one home run and seven RBIs in nine games so far this season with Triple A Iowa.
MLB.com listed Russell as the minor leagues' No. 5 overall prospect coming in to the 2015 season. The same website ranked Bryant as the top overall prospect in the minor leagues.
