Utility infielder

Tillie Shafer was a utility infielder for the New York Giants.

A utility infielder (UI) is a baseball player, usually one who does not have a regular starting role on the team and who is capable of playing more than one of the four defensive infield positions:[1] second base, third base, shortstop, and less typically first base. Utility infielders are generally considered excellent defensive players who do not hit well enough to remain in the starting lineup,[2] but can fill in at multiple defensive positions to give the various starters a rest, or replace a starter late in a game to provide improved defense when the team is winning.

Examples of current utility infielders include Jed Lowrie, Brock Holt, Ben Zobrist, and Marwin González.
