Plate Appearance (PA)
A plate appearance (PA) is any completed turn at the plate, no matter how it ends. Hits, outs, walks, hit-by-pitches, sacrifices and reaching on an error all count. That makes PA the broadest measure of playing time for a hitter, and it is always equal to or larger than his at-bat total.
Formula
Worked example (illustrative numbers): a hitter has 527 at-bats, 60 walks, 5 hit-by-pitches, 3 sacrifice bunts and 5 sacrifice flies.
PA = 527 + 60 + 5 + 3 + 5 = 600
What to Know
Plate appearance vs at-bat: an at-bat removes walks, hit-by-pitches, sacrifice bunts, sacrifice flies and interference or obstruction awards. A walk counts as a plate appearance but not an at-bat. MLB.com notes a batter is not charged a plate appearance if the inning ends on a runner being thrown out while he is at bat.
Plate appearances decide who qualifies for rate titles. Under Official Baseball Rule 9.22(a), a Major League batting, slugging or on-base champion needs at least 3.1 plate appearances per scheduled team game, which works out to about 502 in a 162-game schedule.
Because PA counts every trip to the plate, it is the denominator for walk rate and strikeout rate. It also sits in the bottom of on-base percentage, which uses at-bats plus walks, hit-by-pitches and sacrifice flies.
Frequently Asked Questions
What does PA mean in baseball stats?
PA stands for plate appearance. It counts every completed turn a batter takes at the plate, whether it ends in a hit, an out, a walk, a hit-by-pitch, a sacrifice or reaching on an error.
What is the difference between a plate appearance and an at-bat?
Every completed turn at the plate is a plate appearance. An at-bat leaves out walks, hit-by-pitches, sacrifice bunts, sacrifice flies and interference or obstruction awards. So PA is always equal to or larger than AB.
Does a walk count as a plate appearance?
Yes. A walk is a completed turn at the plate, so it counts as a plate appearance. It does not count as an at-bat, which is why walks have no effect on batting average.
Is a plate appearance the same as an at-bat?
No. The two are often confused, but an at-bat only occurs on certain results, while a plate appearance covers every result between batter and pitcher. A hitter who walks often will show a big gap between the two.
How many plate appearances do you need to qualify for the batting title?
Official Baseball Rule 9.22(a) requires 3.1 plate appearances for each game on a Major League team's schedule. In a 162-game season that is about 502 plate appearances.
When does a batter not get a plate appearance?
MLB.com notes that a batter is not credited with a plate appearance if a runner is thrown out to end the inning while he is at bat, or if the winning run scores on a balk, wild pitch or passed ball during his turn.
