List of Major League Baseball career assists as a center fielder leaders
In baseball, an assist (denoted by "A") is a defensive statistic, baseball being one of the few sports in which the "defensive" team controls the ball. An assist is credited to every defensive player who fields or touches the ball (after it has been hit by the batter) before the recording of a putout, even if the contact was unintentional. For example, if a ball strikes a player's leg and bounces off him to another fielder, who tags the baserunner, the first player is credited with an  assist. A fielder can receive a maximum of one assist per out recorded. An assist is also credited if a putout would have occurred, had another fielder not committed an error. For example, a shortstop might field a ground ball cleanly, but the first baseman might drop his throw. In this case, an error would be charged to the first baseman, and the shortstop would be credited with an assist. A center fielder "(CF)" is the outfielder in baseball who plays defense in center field – the baseball and softball fielding position between left field and right field. In the numbering  system used to record defensive plays, the center fielder is assigned the number 8. Tris Speaker is the all-time leader in career assists as an center fielder with 448. Speaker is the only center fielder with more than 400 career assists.
