Mendick went 2-for-4 with two runs scored Sunday against the Cubs.
Mendick entered the game at shortstop and served as the White Sox's leadoff hitter once Tim Anderson (groin) was forced from the game. While Anderson is expected to hit the injured list, Leury Garcia (side) is day-to-day. If both Anderson and Garcia remain out, Mendick is likely to serve as the team's primary shortstop.
