A “five-tool” baseball player usually refers to a non-pitcher who has a complete ability to play baseball—someone who can hit for average, hit for power, run, throw and catch. “He is a five-tool player: hit, hit for power, catch, run and throw” was cited in print in July 1989. “‘The Five Tools’—speed, an accurate arm, good fielding skills, the ability to hit for power, and, for pitchers, arm strength” was cited in print in April 1991. 
 
A “five-tool player” is rare and usually can command an expensive contract.

Wikipedia: Glossary of baseball
5-tool player
The ideal position player (non-pitcher); an athlete who excels at hitting for average, hitting for power, baserunning skills and speed, throwing ability, and fielding abilities. In Major League Baseball, players considered five-tool players have included Hall of Famers Willie Mays, Andre Dawson, and Duke Snider, as well as Barry Bonds, and Ken Griffey, Jr. Active players who have been described as possessing the five tools include Carlos Gonzalez, Alex Rodriguez, Mike Trout, Matt Kemp, Carlos Beltran, and Ryan Braun. Baseball Digest has argued that the five-tool-player label is overvalued. However, the five tools continue to be the things professional scouts consider when evaluating young players’ potential.
