A baseball bat is a smooth wooden or metal club used in the sport of baseball to hit the ball after it is thrown by the pitcher. By regulation it may be no more than 2.61 inches (6.6 cm) in diameter at the thickest part and no more than 42 inches (1.067 m) in length. Although historically bats approaching 3 pounds (1.4 kg) or 48 oz were used, modern bats of 33 ounces (0.94 kg) are common, topping out at 34 to 36 ounces (0.96 to 1.02 kg).

The Arizona Diamondbacks (often referred to as the D-backs) are an American professional baseball team based in Phoenix, Arizona. The Diamondbacks compete in Major League Baseball (MLB) as a member club of the National League (NL) West Division. The franchise was established on March 9, 1995 and began play in 1998 as an expansion team. The team plays its home games at Chase Field. Along with the Tampa Bay Rays, the Diamondbacks are one of the newest teams in the MLB and are the youngest team to win a World Series, doing so in only their fourth season of existence in 2001.

After a fifth-place finish in their inaugural season, the Diamondbacks made several off-season acquisitions, including future Hall of Fame pitcher Randy Johnson, who won four consecutive Cy Young Awards in his first four seasons with the team. In 1999, Arizona won 100 games and their first division championship. In 2001, they won the World Series over the three-time defending champion New York Yankees, becoming the fastest expansion team in MLB history to win the World Series and the first and only men's major professional sports team in Arizona to win a championship. 22 years later they won their second NLCS and returned to the World Series, losing to the Texas Rangers.

Sandlot ball or sandlot baseball is a competitive and athletic sports game that follows the basic rules and procedures of baseball. It is less organized and structured, as the name alludes to a makeshift field or an empty lot. In the 20th century, it was one of the most popular forms of recreation for children in the United States and many Caribbean and Central American countries.

Henry Chadwick (October 5, 1824 – April 20, 1908) was an English-American sportswriter, baseball statistician and historian, often called the "Father of Baseball" for his early reporting on and contributions to the development of the game. He edited the first baseball guide sold to the public. He is credited with creating box scores, as well as creating the abbreviation "K" that designates a strikeout. He was posthumously inducted into the National Baseball Hall of Fame in 1938.

The Pittsburgh Pirates are an American professional baseball team based in Pittsburgh. The Pirates compete in Major League Baseball (MLB) as a member club of the National League (NL) Central Division. Founded as part of the American Association in 1881 under the name the Allegheny Base Ball Club of Pittsburgh, the club joined the National League in 1887 and was a member of the National League East from 1969 through 1993. The Pirates have won five World Series championships, nine National League pennants, nine National League East division titles and made three appearances in the Wild Card Game.

The Pirates were among the best teams in baseball at the start of the 20th century, playing in the inaugural World Series in 1903 and winning their first title in 1909 behind Honus Wagner. The Pirates took part in arguably the most famous World Series ending, winning the 1960 World Series against the New York Yankees on a walk-off home run by Bill Mazeroski, the only time that Game 7 of the World Series has ever ended with a home run. They won again in 1971 behind Roberto Clemente, the first Latin-American enshrined in the National Baseball Hall of Fame, and in 1979 under the leadership of Willie Stargell.

The Cincinnati Reds are an American professional baseball team based in Cincinnati. The Reds compete in Major League Baseball (MLB) as a member club of the National League (NL) Central Division. They were a charter member of the American Association in 1881 before joining the NL in 1890.

The Reds played in the NL West division from 1969 to 1993, before joining the Central division in 1994. For several years in the 1970s, they were considered the most dominant team in baseball, most notably winning the 1975 and 1976 World Series; the team was colloquially known as the "Big Red Machine" during this time, and it included Hall of Fame members Johnny Bench, Joe Morgan, and Tony Pérez, as well as the controversial Pete Rose, the all-time hits leader in Major League Baseball. Despite their decorated past, the Reds have struggled in recent years, and currently have the longest drought of not winning a playoff series of any MLB team, with their last win coming in 1995. Overall, the Reds have won five World Series championships, nine NL pennants, one AA pennant and 10 division titles. The team plays its home games at Great American Ball Park, which opened in 2003. Bob Castellini has been the CEO of the Reds since 2006. From 1882 to 2025, the Reds' overall win–loss record is 11,017–10,845–139 (a .504 winning percentage).
