The term BASE FIGURE can be broken down into three separate words: Sergeant (8 letters), Infielder (9 letters), and UMP (3 letters). A Sergeant is a rank in the military, usually above a Corporal and below a Lieutenant. An Infielder is a position in baseball, typically referring to the players on the infield who are responsible for fielding ground balls and throwing them to the bases. An UMP is short for Umpire, an official in a game of baseball who is responsible for making calls and enforcing the rules.
