Cubs SS Russell leaves with left hamstring tightness
Russell made a headfirst slide into third on a two-out triple in the fourth. A trainer and manager Joe Maddon then came out to check on the rookie, who was replaced by Javier Baez.
Baez stayed in to play shortstop in the top of the fifth on Monday night.
Russell hit .242 with 13 homers and 54 RBIs during the regular season.
