Three True Outcomes

From BR Bullpen

The Three True Outcomes are a walk, strikeout or home run. They are called this because the three supposedly are the only events that do not involve the defensive team (other than the pitcher). This is clearly untrue, as outfielders can take away potential homers and inside-the-park home runs are influenced by the defense. Additionally, if a defensive player fails to catch a foul pop-up, the batter can wind up with a defense-influenced walk or strikeout (as the at-bat could have been ended earlier).

Prominent recent "TTO" players include Rob Deer and Russ Branyan. Many all-time greats display this skill set as well.
