First Baseman
The first baseman positions himself to the right of the first-base bag and toward the back of the infield dirt when no runner occupies first base or on the first-base bag after a batter reaches first base.
The first baseman is responsible not only for fielding ground balls hit in his vicinity but also for catching throws from other infielders to force a runner out at first base. The first baseman often has to "scoop" one-hop throws from an infielder or pick low throws out of the dirt.
