Overview
A triple is recorded when the batter reaches third base on a hit without the ball leaving the field. Unlike home runs, triples depend on a combination of hit direction, outfield positioning, ballpark dimensions, and the batter's speed. In NPB, triples occur more frequently in spacious parks like Koshien and Sapporo Dome, skewing toward fast runners. Yutaka Fukumoto holds the NPB career record with 115 triples. The triple is the rarest type of hit and is often called the most exciting play in baseball. A batter sprinting full speed into a slide at third electrifies the crowd and can shift game momentum. In recent years, smaller ballparks and defensive shifting have contributed to a declining frequency of triples.
Batted Balls and Ballparks That Produce Triples
The classic triple is a ball driven deep into the right-center or left-center gap. A ball that splits the outfielders and rolls to the wall takes a long time to relay back to the infield, so a fast runner can take third. Parks with irregular wall angles that make caroms hard to field, and parks with deep outfields, produce triples most often. On the batter's side, speed matters, but so does the ability to drive the ball to all fields rather than only pulling it. Left-handed batters reach first base a fraction of a second sooner, so the same batted ball is more likely to become a triple for them. In a small park, by contrast, that same ball either bounces off the wall for a double or clears it for a home run. No other batting record depends so heavily on the ballpark itself.
How a Triple Differs from an Inside-the-Park Home Run and a Ground-Rule Double
The following table sorts out the plays most often confused with a triple.
| Play | Base reached | Scored as | Conditions |
|---|---|---|---|
| Triple | Third base | Hit (triple) | The ball stays in play and the batter stops at third |
| Inside-the-park home run | Home plate | Home run | The ball stays in play without clearing the fence and the batter reaches home |
| Ground-rule double | Second base (batter) | Double | A fair ball bounces into the stands or otherwise becomes dead |
In short, run out one more base and it is an inside-the-park home run; let the ball bounce out of play and it is automatically a double. The triple sits between the two, and its conditions are the hardest of all to line up.
Frequently Asked Questions

The Japanese term is sanruida. In English it is a triple, or a three-base hit.
Q. Who holds the NPB career record for triples?
Yutaka Fukumoto of the Hankyu Braves, with 115. That the mark belongs to a player who was the very definition of speed says a great deal about the nature of the triple.
