Three True Outcomes

From Wiki Gonzalez

The Three True Outcomes = the walk, the strikeout, and the home run.

TTO can be used as an adjective to describe players who seem to do nothing but walk, strike out, or hit home runs.

TTO players are greatly valued (overvalued?) by statheads, because none of the Three True Outcomes are measured very well by batting average, the historic measure of offensive performance. Walks are not in BA at all, strikeouts are no worse than any other kind of out (and superior to GIDPs), and homers only count as much as singles when measured by BA. Theoretically, a TTO player would thus be underrated -- cheaper than a high-average player, but far more productive.

TTO is applied more often to lesser players (Mark Bellhorn, Rob Deer) than to greater players (Jason Giambi, Mark McGwire, Barry Bonds).

The Rob Deer Fan Club was formed on rec.sport.baseball to recognize the accomplishments (aesthetic and otherwise) of one prototypical TTO player.

Origin of the phrase is unknown.
