Top definition
A fantasy baseball player that produces numbers across-the-board for his team. In baseball the usual offensive scoring stats in 5x5 leagbues are runs, home runs, steals, rbi, and batting average.
The term "5tool" could also be use to describe any sports player who is an all-around success, or any person who is formidably capable in a variety of situations.
