Secondary Average
Secondary average, or SecA, is a baseball statistic that measures the sum of extra bases gained on hits, walks, and stolen bases (less times caught stealing) depicted per at bat.James, Bill. ''The Bill James Historical Baseball Abstract''. New York: Villard Books, 1988. Created by Bill James, it is a sabermetric measurement of hitting performance that seeks to evaluate the number of bases a player gained independent of batting average. Unlike batting average, which is a simple ratio of base hits to at bats, secondary average accounts for power (extra base hits), plate discipline ( walks), and speed ( stolen bases minus times caught stealing)."Career Leaders for Secondary Average.''Baseball Almanac'' Baseball-Almanac. 2013. Web. 11 Nov. 2013. Secondary averages have a higher variance than batting averages. Formula The formula to calculate secondary average is: :SecA = \frac where *''BB'' = bases on balls *''TB'' = Total bases *''H'' = Hits *''SB'' = Stolen bases *''CS'' = Cau ...

Baseball Statistics
Baseball statistics play an important role in evaluating the progress of a player or team. Since the flow of a baseball game has natural breaks to it, and normally players act individually rather than performing in clusters, the sport lends itself to easy record-keeping and statistics. Statistics have been kept for professional baseball since the creation of the National League and American League, now part of Major League Baseball. Many statistics are also available from outside Major League Baseball, from leagues such as the National Association of Professional Base Ball Players and the Negro leagues, although the consistency of whether these records were kept, of the standards with respect to which they were calculated, and of their accuracy has varied. Development The practice of keeping records of player achievements was started in the 19th century by Henry Chadwick. Based on his experience with the sport of cricket, Chadwick devised the predecessors to modern-day statist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Total Bases
In baseball statistics, total bases is the number of bases a player gains with hits. It is a weighted sum with values of 1 for a single, 2 for a double, 3 for a triple and 4 for a home run. For example, three singles is three total bases, while a double and a home run is six total bases. Only bases attained from hits count toward this total. Reaching base by other means (such as a base on balls) or advancing further after the hit (such as when a subsequent batter gets a hit) does not increase the player's total bases. In box scores and other statistical summaries, total bases is often denoted by the abbreviation TB. The total bases divided by the number of at bats is the player's slugging percentage. Records Hank Aaron's 6,856 career total bases make him the all-time MLB record holder. Having spent the majority of his career playing in the National League, he also holds that league's record with 6,591 total bases. Aaron hit for 300 or more total bases in a record 15 differ ...

Eric Davis (baseball)
Eric Keith Davis (born May 29, 1962) is an American former center fielder for several Major League Baseball (MLB) teams, most notably the Cincinnati Reds, to which he owes his nickname Eric the Red. Davis was 21 years old when he made his major league debut with the Reds on May 19, 1984. Davis spent eight seasons with the Reds and later played for the Los Angeles Dodgers, Detroit Tigers, Baltimore Orioles, St. Louis Cardinals, and San Francisco Giants. A right-handed batter and fielder, Davis was blessed with a mesmerizing combination of athletic ability, including excellent foot and bat speed, tremendous power, and superlative defensive acumen. He became one of baseball's most exciting players during his peak, achieving a number of rare feats. In 1987, he became the first player in major league history to hit three grand slams in one month and the first to achieve at least 30 home runs and 50 stolen bases in the same season. The Reds selected Davis, a native of Los Angeles, Cali ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Correlation
In statistics, correlation or dependence is any statistical relationship, whether causal or not, between two random variables or bivariate data. Although in the broadest sense, "correlation" may indicate any type of association, in statistics it usually refers to the degree to which a pair of variables are ''linearly'' related. Familiar examples of dependent phenomena include the correlation between the height of parents and their offspring, and the correlation between the price of a good and the quantity the consumers are willing to purchase, as it is depicted in the so-called demand curve. Correlations are useful because they can indicate a predictive relationship that can be exploited in practice. For example, an electrical utility may produce less power on a mild day based on the correlation between electricity demand and weather. In this example, there is a causal relationship, because extreme weather causes people to use more electricity for heating or cooling. However ...

At Bats
In baseball, an at bat (AB) or time at bat is a batter's turn batting against a pitcher. An at bat is different from a plate appearance. A batter is credited with a plate appearance regardless of what happens during their turn at bat, but a batter is credited with an at bat only if that plate appearance does not have one of the results enumerated below. While at bats are used to calculate certain statistics, including batting average and slugging percentage, a player can qualify for the season-ending rankings in these categories only if they accumulate 502 plate appearances during the season. Batters will not receive credit for an at bat if their plate appearances end under the following circumstances: * They receive a base on balls (BB).In 1887, Major League Baseball counted bases on balls as hits (and thus as at-bats). The result was high batting averages, including some near .500, and the experiment was abandoned the following season. * They are hit by a pitch (HBP). * They ...

Caught Stealing
In baseball, a runner is charged, and the fielders involved are credited, with a time caught stealing when the runner attempts to advance or lead off from one base to another without the ball being batted and then is tagged out by a fielder while making the attempt. The runner is said to be caught stealing or thrown out. A time caught stealing cannot be charged to a batter-runner, a runner who is still advancing as the direct result of reaching base. In baseball statistics, caught stealing is denoted by CS. It may result in a rundown. Major League Baseball (MLB) began tracking caught stealing in 1951. The official MLB rules specify that a time caught stealing is charged when: * a runner, attempting a stolen base, is put out; * a runner is caught in a rundown play while stealing, and is tagged out; or * a runner, attempting a stolen base, is safe because a fielder is charged with an error on catching the ball, and in the judgment of the official scorer, the runner would have be ...

Stolen Base
In baseball, a stolen base occurs when a runner advances to a base to which they are not entitled and the official scorer rules that the advance should be credited to the action of the runner. The umpires determine whether the runner is safe or out at the next base, but the official scorer rules on the question of credit or blame for the advance under Rule 10 (Rules of Scoring) of the MLB's Official Rules. A stolen base most often occurs when a base runner advances to the next base while the pitcher is pitching the ball to home plate. Successful base stealers are not only fast but have good base-running instincts and timing. Background Ned Cuthbert, playing for the Philadelphia Keystones in either 1863 or 1865, was the first player to steal a base in a baseball game, although the term ''stolen base'' was not used until 1870. For a time in the 19th century, stolen bases were credited when a baserunner reached an extra base on a base hit from another player. For example, if a ru ...

Hit (baseball Statistics)
In baseball statistics, a hit (denoted by H), also called a base hit, is credited to a batter when the batter safely reaches or passes first base after hitting the ball into fair territory with neither the benefit of an error nor a fielder's choice. Scoring a hit To achieve a hit, the batter must reach first base before any fielder can either tag him with the ball, throw to another player protecting the base before the batter reaches it, or tag first base while carrying the ball. The hit is scored the moment the batter reaches first base safely; if he is put out while attempting to stretch his hit to a double or triple or home run on the same play, he still gets credit for a hit (according to the last base he reached safely on the play). If a batter reaches first base because of offensive interference by a preceding runner (including if a preceding runner is hit by a batted ball), he is also credited with a hit. Types of hits A hit for one base is called a single, for two ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bases On Balls
A base on balls (BB), also known as a walk, occurs in baseball when a batter receives four pitches that the umpire calls '' balls'', and is in turn awarded first base without the possibility of being called out. The base on balls is defined in Section 2.00 of baseball's Official Rules, and further detail is given in 6.08(a). It is considered a faux pas for a professional player to literally walk to first base; the batter-runner and any advancing runners normally jog on such a play. The term "base on balls" distinguishes a walk from the other manners in which a batter can be awarded first base without liability to be put out (e.g., hit by pitch (HBP), catcher's interference). Though a base on balls, catcher's interference, or a batter hit by a pitched ball all result in the batter (and possibly runners on base) being awarded a base, the term "walk" usually refers only to a base on balls, and not the other methods of reaching base without the bat touching the ball.

Bill James
George William James (born October 5, 1949) is an American baseball writer, historian, and statistician whose work has been widely influential. Since 1977, James has written more than two dozen books devoted to baseball history and statistics. His approach, which he termed sabermetrics in reference to the Society for American Baseball Research (SABR), scientifically analyzes and studies baseball, often through the use of statistical data, in an attempt to determine why teams win and lose. In 2006, ''Time'' named him in the ''Time'' 100 as one of the most influential people in the world. In 2003, James was hired as senior advisor on Baseball Operations for the Boston Red Sox and worked for the team for 17 years during which they won four World Series championships. Early life James was born in Holton, Kansas; his mother died in 1954 when he was five. His father was a janitor and a handyman. After four years at the University of Kansas (KU) residing at Stephenson Scholarship H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
