Generally 400 but the amount has varied as the number of games played changes. For instance George Brett won the batting title with a .390 average in a strike shortened season. Nevertheless walks do not count, since they do not count as at bats. In the early 70s a player lost the batting crown with 399 at bats when 400 were required. This rule has changed however. Now, a player just short of the required at bats could ADD the number of hitless at bats (generally meaning walks) to the number of at bats which will permit the player to still win the batting crown as long as the average does not drop below the player just below him. ---- To win a batting title in MLB, a batter must have a minimum of 502 total plate appearences for the season. Yes, any at bat that results in a non-official at bat (walk, sacrifice, hit by pitch) counts towards the total number of plate appearances.
Walks count as an official plate appearance and are used in determining whether a player has met the minimum number of plate appearances needed to be eligible to win the batting title but are not used in calculating a player's batting average.
No, a hit by pitched ball is not an official at bat, just like a base on balls is not an official at bat. Yes. It will not show up underneath the AB statistic for a player but it does count towards the number of at bats needed to win a batting title. Actually, number of at bats is not the term used to determined a batting title. The term is actually "plate appearances" and includes official "at bats", walks, hit by pitched ball, catcher interference, sacrifices, sacrifice flys, which do not count as "at bats". Official "at bats" are recorded for a hitter who gets a base hit, reaches on an error, strikes out, or hits into an out. Batting averages are determined by dividing hits by official at bats, so, a hit by pitched ball does not count toward one's batting average as it is not an "at bat", but is a "plate appearance".
No. Walks do not count toward batting average. If you get a walk in your first at bat, you will still be 0-0.
Yes, but they don't affect your batting average.
No, walks do not count as an at-bat.
Yes. While a sacrifice fly does not count against your batting average it does against your on base percentage. On base % = (hits + walks + hits by pitch) / (at-bats + walks + hits by pitch + sacrifice flies)
No, walks do not factor. They don't count as At Bats and therefore don't affect the batting average. For example: a player is at the plate 4 times; he gets walked twice and has one hit. The two walks don't count as At Bats. He therefore has 1 Hit in 2 AB which, of course, is a .500 BA.
The batting average is the percent of times a batter gets a successful hit per official times at bat. It is determined by dividing the hits by the times at bat, i. e. times at bat 10; hits 3. 3 divided by 10 gives you a .300 batting average, or the batter gets a hit 30% of the times he has an official at bat. Base on balls (walks), sacrifice hits, sacrifice flies, hit by pitch ball, and catcher interference do not count as an official at bat.
The official formula for on-base percentage is (Hits + Walks + Hit by pitch) / (At-bats + Walks + Hit by pitch + sacrifice flies). Reaching base on an error goes against your BA and OBP, as it doesn't count as a hit but counts as an at bat.
If a batter walks or gets hit by a pitch, the at-bat counts as a plate appearance so that the player doesn't lose points on their batting average.
Walks are not counted in figuring out Batting Averages. It's basically like you didn't take an at- bat for walks.
