McLain went 3-for-5 with a walk and a run scored in Friday's 9-0 victory over the Cubs.
All three knocks were singles in the first three-hit game of the rookie's career. The shortstop has been a consistent offensive threat since being called up in mid-May, hitting safely in eight of his first 10 big-league games. Over his last five appearances, McLain has totaled nine hits (four for extra bases), five RBI, three walks and six runs scored across 24 at-bats. For the moment, he appears to be the Reds' everyday shortstop, as Jose Barrero has started playing more outfield with Wil Myers (illness) on the injured list.
