Coombs. 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, consider Pennock among the greatest left-handed pitchers of all time. Post-playing career Pennock became the general manager of the Charlotte Hornets, a Red Sox' farm team of the Piedmont League, prior to the 1935 season. 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. He also created a "Grandstand Managers Club", the first in baseball history, allowing fans to give feedback to the team, and advocated for the repeal of the Bonus Rule. Pennock opposed racial integration in baseball. In 1947, when Jackie Robinson was signed to the Brooklyn Dodgers, Pennock called Dodgers team president Branch Rickey before the Dodgers' series in Philadelphia and told him not to "bring that nigger here with the rest of the team." He further threatened to boycott a 1947 game between the Phillies and Dodgers if Robinson played. Accusations of Pennock's alleged racism have come into question upon the 2016 release of the book Herb Pennock: Baseball's Faultless Pitcher written by Keith Craig. The only source of the story about the call to Rickey was from the 1976 book The Lords of Baseball by Harold Parrott who claimed to have listened in on the conversation on an extension line, something which didn't exist at the time. Robinson had stated that the call was made by Carpenter and not
