In baseball, an unassiste triple play occurs when a defensive player makes all three putouts by himself in one continuous play, without any teammates touching the ball (assist). In Major League Baseball, it is the rarest of individual feats, occurring less frequently than even a perfect game and hitting four home runs in one game (although these are equal if a disputed unassisted triple play is included). During a span of over 65 seasons (June 1927 to September 1992), there was only one unassisted triple play in the major leagues, made in July 1968. Even "ordinary" (assisted) triple plays are fairly rare, occurring a few times per year.
