Given the question: Information: - In baseball, the pitcher is the player who throws the baseball from the pitcher's mound toward the catcher to begin each play, with the goal of retiring a batter, who attempts to either make contact with the pitched ball or draw a walk. In the numbering system used to record defensive plays, the pitcher is assigned the number 1. The pitcher is often considered the most important defensive player, and as such is situated at the right end of the defensive spectrum. There are many different types of pitchers, such as the starting pitcher, relief pitcher, middle reliever, lefty specialist, setup man, and closer. - Chicago (or ), officially the City of Chicago, is the third-most populous city in the United States, and the fifth-most populous city in North America. With over 2.7million residents, it is the most populous city in the state of Illinois and the Midwestern United States, and the county seat of Cook County. The Chicago metropolitan area, often referred to as Chicagoland, has nearly 10million people and is the third-largest in the U.S. - The International Softball Federation is the international governing body for the sport of softball. The ISF is a non-profit corporation recognized by the International Olympic Committee (IOC) and SportAccord (formerly the General Association of International Sports Federations). - Catcher is a position for a baseball or softball player. When a batter takes his/her turn to hit, the catcher crouches behind home plate, in front of the (home) umpire, and receives the ball from the pitcher. In addition to this primary duty, the catcher is also called upon to master many other skills in order to field the position well. The role of the catcher is similar to that of the wicket-keeper in cricket. - In baseball (hardball or softball), a starting pitcher or starter is the first pitcher in the game for each team. A pitcher is credited with a game started if they throw the first pitch to the opponent's first batter of a game. A pitcher who enters the game after the first pitch of the game is a relief pitcher. Starting pitchers are expected to pitch for a significant portion of the game, although their ability to do this depends on many factors, including effectiveness, stamina, health, and strategy. - A tournament held in 1933 at the Chicago World's Fair spurred interest in the game. The Amateur Softball Association (ASA) of America (founded 1933) governs the game in the United States and sponsors annual sectional and World Series championships. The World Baseball Softball Confederation (WBSC) regulates rules of play in more than 110 countries, including the United States and Canada; before the WBSC was formed in 2013, the International Softball Federation filled this role. Women's fastpitch softball became a Summer Olympic sport in 1996, but it (and baseball) were dropped from the 2012 Games; they will be reinstated for the 2020 Games. - In baseball and softball, a relief pitcher or reliever is a pitcher who enters the game after the starting pitcher is removed due to injury, ineffectiveness, fatigue, ejection, or for other strategic reasons, such as being substituted by a pinch hitter. Relief pitchers are further divided informally into various roles, such as closers, set-up relief pitchers, middle relief pitchers, left/right-handed specialists, and long relievers. Whereas starting pitchers usually rest several days before pitching in a game again due to the number of pitches thrown, relief pitchers are expected to be more flexible and typically pitch more games but with fewer innings pitched. A team's staff of relievers is normally referred to metonymically as a team's bullpen, which refers to the area where the relievers sit during games, and where they warm-up prior to entering the game. - Baseball is a bat-and-ball game played between two teams of nine players each, who take turns batting and fielding. - Kaila Holtz ( born September 26 , 1981 in Edmonton , Alberta ) is a Canadian softball pitcher .
