Herbert Jefferis Pennock (February 10, 1894 – January 30, 1948) was an American professional baseball pitcher and front-office executive. He played in Major League Baseball from 1912 through 1933, and is best known for his time spent with the star-studded New York Yankee teams of the mid to late 1920s and early 1930s.

Pennock was signed by the Philadelphia Athletics in 1912, but was used sparingly by the Athletics and the Boston Red Sox, who bought his contract in 1915. After returning from military service in 1919, Pennock became a regular contributor for the Red Sox. The Yankees acquired Pennock after the 1922 season, and he served as a key member of the pitching staff as the Yankees won four World Series championships. After retiring as a player, Pennock served as a coach and farm system director for the Red Sox, and as general manager of the Philadelphia Phillies.

Pennock was regarded as one of the greatest left-handed pitchers in baseball history. He died of a cerebral hemorrhage in 1948, and was inducted into the National Baseball Hall of Fame later that year.

Early life

Pennock was born on February 10, 1894, in Kennett Square, Pennsylvania. His father, Theodore Pennock, and mother, Mary Louise Pennock (née Sharp), were of Scotch-Irish and Quaker descent. Herb was the youngest of four children.

Pennock attended Westtown School and Cedarcroft Boarding School, where he played for the baseball team. After struggling as a first baseman, with weak offense and an inability to throw the ball straight, Pennock was converted by his Cedarcroft coach into a pitcher. Mack signed Pennock in 1912 to play for his collegiate team based in Atlantic City. Pennock's father insisted that he sign under an alias in order to protect his collegiate eligibility. Pennock threw a no-hitter against a traveling Negro league baseball team, and Mack promoted him to the Athletics. Former major leaguer Mike Grady, a neighbor of Pennock's in Kennett Square, took Pennock under his wing, while Bender taught Pennock to throw a screwball. In the 1914 season, Pennock posted an 11–4 win–loss record with a 2.79 earned run average (ERA) in innings pitched for the Athletics, and pitched three scoreless innings in the 1914 World Series, which the Athletics lost to the Boston Braves. Mack let Bender go after the season, naming Pennock his Opening Day starting pitcher in 1915. On Opening Day, Pennock threw a one-hit complete game shutout against the Boston Red Sox. Mack later regarded this sale as his greatest mistake.

Boston Red Sox

With a deep pitching staff in place, the Red Sox loaned Pennock to the Providence Grays of the International League in August for the remainder of the 1915 season. He split the 1916 season between the Red Sox and the Buffalo Bisons, also in the International League. With Buffalo, Pennock pitched to a 1.67 ERA, as Buffalo won the league pennant.

Pitching in minor league baseball, Pennock began to regain confidence. Pennock pitched for a team fielded by the Navy, defeating a team composed of members of the United States Army in an exhibition for George V, the King of England in Stamford Bridge stadium. After the game, Ed Barrow, the new manager of the Red Sox, signed Pennock to a new contract after promising to use him regularly during the 1919 season. the New York Yankees began to negotiate with the Red Sox to acquire Pennock. The Yankees traded Norm McMillan, George Murray, and Camp Skinner to the Red Sox for Pennock that offseason.

New York Yankees

Pennock pitched to a 19–6 win–loss record in the 1923 season, his first with the Yankees, leading the American League (AL) in winning percentage () and finishing sixth in wins. Pitching in the 1923 World Series, Pennock defeated the New York Giants in game two, on October 11, to end their eight-game World Series winning streak. He recorded a save in securing the Yankees' win in game four, and pitched to the win in game six on one day of rest, clinching the Yankees' first World Series championship.

In the 1924 season, he pitched to a 21–9 win–loss record with a 2.83 ERA while striking out a career-high 101 batters. His win total was second in the AL, behind Walter Johnson, while his ERA was third behind Johnson and Tom Zachary, and he finished fourth in strikeouts behind Johnson, Howard Ehmke, and teammate Bob Shawkey. Pennock's 277 innings pitched and 1.220 walks plus hits per inning pitched (WHIP) ratio led the AL in the 1925 season, while his 2.96 ERA was second-best, behind Stan Coveleski. In the 1926 season, he posted a career-high 23 wins, finishing second in the AL to George Uhle. He again led the AL in WHIP (1.265), and issued the fewest walks per nine innings pitched (1.453). During the pennant race, The Sporting News called Pennock the "best left-hander in the majors".

The Yankees reached the World Series, facing the Pittsburgh Pirates. Pennock pitched a complete game against the Pirates in game three of the 1927 World Series, not allowing a hit until the eighth inning. Pennock's performance drew praise from teammate Babe Ruth. The Yankees swept the series from Pittsburgh. After pitching a three-hit shutout against the Red Sox on August 12, 1928, he missed the remainder of the season, including the 1928 World Series, with an arm injury. His five shutouts and 0.085 home runs per nine innings pitched led the AL. His 2.56 ERA trailed only Garland Braxton, while his 17 wins tied for eighth place. Though the Yankees defeated the Cardinals in the 1928 World Series, the Yankees' starting rotation without Pennock was likened to "a three-stringed ukulele." Pennock won his 200th career game during the 1929 season, becoming the third left-handed pitcher to reach that mark. and 1931 (1.426). Pennock pitched four innings of relief against the Chicago Cubs in the 1932 World Series, recording two saves. The New York chapter of the Baseball Writers' Association of America named him their player of the year.

Return to Boston

Eddie Collins, a former teammate with the Athletics now serving as the general manager of the Red Sox, signed Pennock to their 1934 roster. In his last season pitching in the major leagues, Pennock served as a relief pitcher for the Red Sox. Pennock was a part of seven World Series championship teams (1913, 1915, 1916, 1923, 1927, 1928, and 1932), though he played in four World Series as a member of the winning team. Many, including Mack, considered Pennock among the greatest left-handed pitchers of all time. He returned to the Red Sox in 1936 as the first base and pitching coach under manager Joe Cronin. He served in this role through the 1938 season. In 1939, Pennock became the assistant supervisor of Boston's minor league system, reporting to Billy Evans, then succeeded Evans as Director of Minor League Operations late in the 1940 season.

In December 1943, R. R. M. Carpenter Jr., the new owner of the Philadelphia Phillies, hired Pennock as his general manager, after receiving a recommendation from Mack. Carpenter gave Pennock a lifetime contract. Pennock filled Carpenter's duties when the team's owner was drafted into service during World War II in 1944. As general manager, Pennock changed the team's name to the "Blue Jays"—a temporary measure abandoned after the season—and invested $1 million ($ in current dollar terms) into players who would become known as the "Whiz Kids", who won the National League pennant in 1950, including Curt Simmons and Willie Jones. and advocated for the repeal of the Bonus Rule.

Pennock opposed racial integration in baseball. He further threatened to boycott a 1947 game between the Phillies and Dodgers if Robinson played. Robinson had stated that the call was made by Carpenter and not Pennock. Additionally in his book, Craig mentioned that Pennock and his wife took in a black woman who had fled an abusive husband in the 1930s, lived with their family for the rest of her life and was buried next to him. Pennock had appeared to be in good health, even inviting friends to join him at Madison Square Garden to attend a boxing match, prior to being stricken.

Honors

Pennock was honored with "Herb Pennock Day" on April 30, 1944, in Kennett Square. In 1998, an attempt to erect a statue in Kennett Square in his honor was blocked due to his support of segregation in baseball.

Fred Heimach, a teammate of Pennock, once called him the smartest ball player he knew. In 1981, Lawrence Ritter and Donald Honig included Pennock in their book The 100 Greatest Baseball Players of All Time. He was inducted in the International League Hall of Fame in 1948. Noted baseball photographer Charles M. Conlon considered Pennock one of his favorite subjects to photograph.

Personal life

Pennock was nicknamed "the Squire of Kennett Square." While a member of the Yankees, Pennock rented an apartment on Grand Concourse in The Bronx, where his wife and children stayed while the Yankees played their home games. He also raised hounds and silver foxes for their pelts. He also grew flowers and vegetables on his farm.
