Three True Outcomes
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 and catcher). This ignores outfielders taking away potential homers at the wall, and inside-the-park home runs, and the like; however, over a career those events make up a very small portion of the total.
Prominent recent "TTO" players include Rob Deer, Jack Cust, Russell Branyan, Ryan Howard, and Adam Dunn. Many all-time greats display this skill set as well, like Barry Bonds, Mark McGwire, and Jim Thome.
