Definition. An official at-bat comes when a batter reaches base via a fielder’s choice, hit or an error (not including catcher’s interference) or when a batter is put out on a non-sacrifice. (Whereas a plate appearance refers to each completed turn batting, regardless of the result.)
P/PA is a simple stat that quantifies how many pitches are thrown per plate appearance. It can be used for both hitters and pitchers, although it is more frequently referred to when assessing hitters.
PA = Plate Appearance. H = Hit (single, double, triple, or home run) BB = Walk (Four balls before three strikes) K = Strikeout (Three strikes before four balls)The Infinitely Long MLB Plate Appearance.

In short, a walk is not an At-Bat (AB) because At-Bats are used to calculate a player’s batting average. Including walks as an At-Bat would considerably change a player’s batting average, so walks are removed as an official At-Bat.
In baseball statistics, a player is credited with a plate appearance (denoted by PA) each time he completes a turn batting. Under Rule 5.04(c) of the Official Baseball Rules, a player completes a turn batting when he is put out or becomes a runner.

OBP does not credit the batter for reaching base on fielding errors, fielder’s choice, uncaught third strikes, fielder’s obstruction, or catcher’s interference.
Babe Ruth is the all-time leader with a career slugging percentage of .6897.

Reaching base on an error does not count as a hit, nor does it count as a time on base for purposes of on-base percentage.
A player is awarded a run if he crosses the plate to score his team a run. When tallying runs scored, the way in which a player reached base is not considered. If a player reaches base by an error or a fielder’s choice, as long as he comes around to score, he is still credited with a run.
A batting average of . 300 or higher is considered very good in the Major Leagues. For the batting average, it doesn’t matter if a hit is a single or a home run, it still just counts as a single hit. The record for the highest career batting average is held by Ty Cobb with a .
Strikeout to walk ratio (K/BB): You can’t simply look at strikeout-to-walk ratio and make firm judgments about a pitcher. But as supporting evidence goes, it’s one of the most useful “eyeball” stats out there.
The Best Ways to Evaluate Hitters
For those who don’t know, OPS is “on-base plus slugging,” or a hitter’s on-base percentage (OBP) plus his slugging percentage (SLUG). Crude as it is, it is a better reflection of a hitter’s talent than the traditional trio of average, homers and RBI. Hitters exist to score runs.
Baserunning statistics[edit]- CS - Caught stealing - times tagged out when attempting to steal.
SB - Stolen base - number of bases advanced other than on batted balls, walks, or hits by pitch.
R - Runs scored - times reached home base legally and safely.
OPS adds on-base percentage and slugging percentage to get one number that unites the two. It’s meant to combine how well a hitter can reach base, with how well he can hit for average and for power. It can also be used in evaluating pitchers; when used in that context, it is referred to as OPS against.
Perfect Game (PG) started 25 years ago with one goal – grow the game of baseball by creating opportunities for student-athletes in the Midwest. Over the years, Perfect Game has grown into the premier platform for amateur baseball players that want to play collegiate and professional baseball all across the nation.
Fielder’s choice is not called by the umpires on the field of play; rather, it is recorded by the official scorer to account for the offensive player’s advance without crediting him with an offensive statistic such as a hit or stolen base.
A sacrifice fly does not count as an at-bat and therefore does not count against a player’s batting average. The thinking behind the rule is that with a man on third base and fewer than two outs, a batter will often intentionally try to hit a fly ball, sacrificing his time at bat to help score a run.
260 batting average is the league average then a batting average of . 280 is pretty solid, . 300 is very good, and significantly higher than . 300 is great.
Definition. Slugging percentage represents the total number of bases a player records per at-bat. Unlike on-base percentage, slugging percentage deals only with hits and does not include walks and hit-by-pitches in its equation. Slugging percentage differs from batting average in that all hits are not valued equally.
360 is considered to be above average. If a player’s OBP hits . 370 or higher, it puts them among the top players in the league for this statistic.
