Strikeouts Per 9 Innings Pitched
In baseball statistics, strikeouts per nine innings pitched (abbreviated K/9, SO/9, or SO/9IP) is the mean of strikeouts (or Ks) by a pitcher per nine innings pitched. It is determined by multiplying the number of strikeouts by nine, and dividing by the number of innings pitched.

Baseball Statistics
Baseball statistics include a variety of metrics used to evaluate player and team performance in the sport of baseball. Because the flow of a baseball game has natural breaks to it, and player activity is characteristically distinguishable individually, the sport lends itself to easy record-keeping and compiling statistics. Baseball "stats" have been recorded since the game's earliest beginnings as a distinct sport in the middle of the nineteenth century, and as such are extensively available through the historical records of leagues such as the National Association of Professional Base Ball Players and the Negro leagues, although the consistency, standards, and calculations are often incomplete or questionable. Since the National League (baseball), National League (NL) was founded in 1876, statistics in the most elite levels of professional baseball have been kept at some level, with efforts to standardize the stats and their compilation improving during the early 20th centur ...

Kerry Wood
Kerry Lee Wood (born June 16, 1977) is an American former baseball pitcher who played 14 seasons in Major League Baseball (MLB) for the Chicago Cubs, Cleveland Indians, and New York Yankees. Wood first came to prominence as a 20-year-old rookie, when he recorded 20 strikeouts in a one-hit shutout against the Houston Astros, which some have argued may be the greatest single-game pitching performance in MLB history. The game also made Wood the co-holder of the MLB record for strikeouts in a single game (20) and earned Wood the nickname "Kid K". He was later named the 1998 National League Rookie of the Year. Wood went on to record over 200 strikeouts in four out of his first five seasons, with a high of 266 in 2003. He holds several MLB strikeout records. Though he struggled with injuries throughout his career, Wood was twice named an All-Star.

Walk
Walking (also known as ambulation) is one of the main gaits of terrestrial locomotion among legged animals. Walking is typically slower than running and other gaits. Walking is defined as an "inverted pendulum" gait in which the body vaults over the stiff limb or limbs with each step. This applies regardless of the usable number of limbs—even arthropods, with six, eight, or more limbs, walk. In humans, walking has health benefits including improved mental health and reduced risk of cardiovascular disease and death. Difference from running The word ''walk'' is descended from the Old English ''wealcan'' 'to roll'. In humans and other bipeds, walking is generally distinguished from running in that only one foot at a time leaves contact with the ground and there is a period of double-support. In contrast, running begins when both feet are off the ground with each step. This distinction has the status of a formal requirement in competitive walking events. For quadrupedal speci ...

BABIP
In baseball statistics, batting average on balls in play (abbreviated BABIP) is a measurement of how often batted balls result in hits, excluding home runs. It can be expressed as, "when you hit the ball and it’s not a home run, what’s your batting average?" The statistic is typically used to evaluate individual batters and individual pitchers. Calculation BABIP is computed per the following equation, where H is hits, HR is home runs, AB is at bats, K is strikeouts, and SF is sacrifice flies. BABIP = \frac Effect As compared to batting average, which is simply hits divided by at bats, BABIP excludes home runs and strikeouts from consideration while treating sacrifice flies as hitless at bats. In Major League Baseball (MLB), .300 is considered an average BABIP. Various factors can impact BABIP, such as a player's home ballpark; for batters, being speedy enough to reach base on infield hits; or, for pitchers, the quality of their team's defense. Usage BABIP is commonly use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minor League Baseball
Minor League Baseball (MiLB) is a professional baseball organization below Major League Baseball (MLB), constituted of teams affiliated with MLB clubs. It was founded on September 5, 1901, in response to the growing dominance of the National League (baseball), National League and American League, as the National Association of Professional Baseball Leagues (NAPBL or NA).

The association of minor leagues remained independent throughout the early 20th century, protected by agreements with the major leagues to ensure they were compensated when minor-league players were signed by major-league clubs. Later, Minor League Baseball evolved to be constituted entirely of farm team, affiliates of larger clubs, giving young prospects a chance to develop the ...
