ultimate grand slam
- A grand slam by a member of the home team when they are exactly three runs behind in the bottom of the final inning, thus overcoming a 3-run deficit and winning the game with one swing. See also walk-off home run.

Unassisted double plays are rare, and unassisted triple plays are extremely rare.

uncontested steal, undefended steal
- If a base runner successfully advances to the next base while the pitcher is delivering the ball to home plate but the catcher does not attempt to throw him out, then the steal may be scored as an uncontested or undefended steal. In the game's statistics, the runner would not be credited with a stolen base. Also called defensive indifference. See also stolen base, fielder's choice.

When his fastball is down or in the middle of the strike zone, opponents hit .270 with a miss rate of 15 percent."
