Baseball statistics refers to a variety of metrics used to evaluate player and team performance in the game of baseball.
Gregory Alan Maddux, also known as "Mad Dog" and "the Professor," is an American former professional baseball pitcher who played 23 seasons in Major League Baseball (MLB), primarily with the Atlanta Braves and Chicago Cubs. He won the 1995 World Series with the Braves over the Cleveland Indians. Maddux was the first pitcher in MLB history to win the Cy Young Award four consecutive years (1992–1995), matched by only one other pitcher, Randy Johnson. During those four seasons, Maddux had a 75–29 record with a 1.98 earned run average (ERA), while allowing less than one baserunner per inning.
In baseball statistics, walks plus hits per inning pitched (WHIP) is a sabermetric measurement of the number of baserunners a pitcher has allowed per inning pitched. WHIP is calculated by adding the number of walks and hits allowed and dividing this sum by the number of innings pitched.
In baseball, a left-handed specialist is a relief pitcher who throws left-handed and specializes in pitching to left-handed batters, weak right-handed batters, and switch-hitters who bat poorly right-handed. Because baseball practices permanent substitution, these pitchers frequently pitch to a very small number of batters in any given game, and rarely pitch to strictly right-handed batters. Most Major League Baseball (MLB) teams have several left-handed pitchers on their rosters, at least one of whom is a left-handed specialist. A left-handed specialist is sometimes called a LOOGY, coined by John Sickels, and may be used pejoratively.
In baseball statistics, batting average against, also known as opponents' batting average, is a statistic that measures a pitcher's ability to prevent hits during official at bats. It can alternatively be described as the league's hitters' combined batting average against the pitcher.
Throughout the history of baseball, the rules have frequently changed as the game continues to evolve. A few common rules most professional leagues have in common is that four balls is a base on balls, three strikes is a strikeout, and three outs end a half-inning.

Edwin Americus Rommel was an American baseball player, coach, and umpire who played as a right-handed pitcher and in Major League Baseball. He spent his entire playing career (1920–1932) with the Philadelphia Athletics. He is considered to be one of the earlier adaptors of the modern knuckleball.
James Rodney Richard was an American professional baseball player. He played his entire career in Major League Baseball as a right-handed starting pitcher for the Houston Astros from 1971 to 1980. Richard led the National League (NL) twice in strikeouts and was named an NL All-Star player in 1980.

In baseball statistics, strikeouts per nine innings pitched is the mean of strikeouts 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.

The 1945 Detroit Tigers was the team's 45th since they entered the American League in 1901. The team won the American League pennant, then went on to win the 1945 World Series, defeating the Chicago Cubs 4 games to 3. It was the second World Series championship for the Tigers. Detroit pitcher Hal Newhouser was named the American League's Most Valuable Player for the second consecutive season.
The 1915 Detroit Tigers won a club-record 100 games and narrowly lost the American League pennant to the Boston Red Sox, who won 101 games. Though four other Tigers teams have won 100 games, only the 1934 Tigers had a better winning percentage. The 1915 Detroit Tigers team is remembered for its all-star outfield of Ty Cobb, Sam Crawford, and Bobby Veach—who finished #1, #2, and #3 in the American League in both runs batted in and total bases. Baseball historian Bill James ranks the Tigers' 1915 outfield as the best in major league history.

Frank W. "Dutch" Ulrich was a Czech-American professional baseball player who played three seasons for the Philadelphia Phillies from 1925 through 1927. In 1927, he had the seventh-best earned run average (ERA) in the National League (NL). He batted and threw right-handed.
In baseball statistics, earned run average (ERA) is the average of earned runs allowed by a pitcher per nine innings pitched. It is determined by dividing the number of earned runs allowed by the number of innings pitched and multiplying by nine. Thus, a lower ERA is better. Runs resulting from passed balls, defensive errors, and runners placed on base at the start of extra innings are recorded as unearned runs and omitted from ERA calculations.
