James Hoyt Wilhelm (July 26, 1922 – August 23, 2002), nicknamed "Old Sarge", was an American professional baseball pitcher in Major League Baseball (MLB) with the New York Giants, St. Louis Cardinals, Cleveland Indians, Baltimore Orioles, Chicago White Sox, California Angels, Atlanta Braves, Chicago Cubs, and Los Angeles Dodgers between 1952 and 1972. Wilhelm was elected to the Baseball Hall of Fame in 1985.
Wilhelm grew up in North Carolina, fought in World War II, and then spent several years in the minor leagues before starting his major league career at the age of 29. He was best known for his knuckleball, which enabled him to have great longevity. He appeared occasionally as a starting pitcher, but pitched mainly as a reliever. Wilhelm won 124 games in relief, which is still the major league record as of 2026. He was the first pitcher to reach 200 saves, and the first to appear in 1,000 games.
Wilhelm was nearly 30 years old when he entered the major leagues, and pitched until he was nearly 50. He retired with one of the lowest career earned run averages, 2.52, in baseball history. After retiring as a player in 1972, Wilhelm held longtime coaching jobs with the New York Yankees and Atlanta Braves. He lived in Sarasota, Florida, for many years, and died there in 2002.
James Hoyt Wilhelm was born on July 26, 1922, long thought to have been 1923, in Huntersville, North Carolina. He was one of eleven children born to poor tenant farmers John and Ethel (née Stanley) Wilhelm in Huntersville, North Carolina. He played baseball at Cornelius High School in Cornelius, North Carolina. Knowing he could not throw fast, he began experimenting with a knuckleball after reading about pitcher Dutch Leonard. He practiced honing it with a tennis ball, hoping it was his best shot at Big League success.
Wilhelm made his professional debut with the Mooresville Moors of the Class-D North Carolina State League in 1942. He served in the United States Army in the European Theater during World War II and participated in the Battle of the Bulge, where he was wounded, earning the Purple Heart for his actions. He rose to the rank of staff sergeant while in the Army, and played his entire career with a piece of fragmentation lodged in his back as a result of the wounds he received in battle. Wilhelm carried the nickname "Old Sarge" because of his service in the military.
After his release from the military, Wilhelm returned to the Moors for the 1946 season, and earned 41 wins over the 1946 and 1947 seasons. He later recalled being dropped from a Class D minor league team and having the manager tell him to forget about the knuckleball, but he persisted with it.
The Boston Braves purchased Wilhelm from Mooresville in 1947, and on November 20, 1947, he was drafted by the New York Giants from the Braves in the 1947 minor league draft.
Wilhelm's first assignment in the Giants organization was in Class B with the 1948 Knoxville Smokies, for whom he registered 13 wins and nine losses. He also spent a few games that season with the Class A Jacksonville Tars of the South Atlantic League, and returned to Jacksonville in 1949, earning a 17–12 win–loss record and a 2.66 earned run average (ERA). Wilhelm was promoted to the Class AAA Minneapolis Millers in 1950, where he was the starting pitcher in 25 of the 35 games he pitched in, registering a 15–11 record with a 4.95 ERA. His role in 1951 with the Millers was the same as the year before, primarily as a starter, but also making eleven relief appearances. His ERA came down to 3.94 in 1951, but his record fell to 11–14.
Though Wilhelm was primarily a starting pitcher in the minor leagues, he had been called up to a Giants team whose strong starting pitchers had led them to a National League (NL) pennant the year before. Giants manager Leo Durocher did not think that Wilhelm's knuckleball approach would be effective for more than a few innings at a time. He assigned Wilhelm to the team's bullpen.
Wilhelm made his MLB debut with the Giants on April 18, 1952, at age 29, giving up a hit and two walks while only recording one out. On April 23, 1952, in his third game with the New York Giants, Wilhelm batted for the first time in the majors. Facing rookie Dick Hoover of the Boston Braves, Wilhelm hit a home run over the short right-field fence at the Polo Grounds. Although he went to bat a total of 432 times in his career, he never hit another home run.
Pitching exclusively in relief, Wilhelm led the NL with a 2.43 ERA in his rookie year. He won 15 games and lost three. Wilhelm finished fourth in the NL Most Valuable Player Award voting that season, behind rookie reliever Joe Black of the Dodgers. Jim Konstanty had won it for the Phillies in 1950, and Ellis Kinder had finished seventh in the AL voting in 1951, so it was a time when relief pitchers were starting to receive appreciation from the sportswriters. Wilhelm finished second in the Rookie of the Year Award voting to Joe Black. Wilhelm made 69 relief appearances in 1953, his win–loss record decreased to 7–8 and he issued 77 walks against 71 strikeouts. Wilhelm was named to the NL All-Star team that year, but he did not play in the game because team manager Charlie Dressen did not think that any of the catchers could handle his knuckleball. The Giants renewed Wilhelm's contract in February 1954.
In 1954, Wilhelm was a key piece of the pitching staff that led the 1954 Giants to a world championship. He pitched 111 innings, finishing with a 12–4 record and a 2.10 ERA. During one of Wilhelm's appearances that season, catcher Ray Katt committed four passed balls in one inning to set the major league record; the record has subsequently been tied twice. When Stan Musial set a record by hitting five home runs in a doubleheader that year, Wilhelm was pitching in the second game and gave up two of the home runs. The 1954 World Series represented Wilhelm's only career postseason play. He pitched 2+1⁄3 innings over two games, earning a save in the third game. The team won the World Series in a four-game sweep.
Wilhelm's ERA increased to 3.93 over 59 games and 103 innings pitched in 1955, but he managed a 4–1 record. He finished the 1956 season with a 4–9 record and a 3.83 ERA in 89+1⁄3 innings. Sportswriter Bob Driscoll later attributed Wilhelm's difficulties in the mid-1950s to the decline in the career of Giants catcher Wes Westrum, writing that baseball was "a game of inches, and for Hoyt, Wes had been that inch in the right direction."
On February 26, 1957, Wilhelm was traded by the Giants to the St. Louis Cardinals for Whitey Lockman. At the time of the trade, St. Louis manager Fred Hutchinson described Wilhelm as the type of pitcher who "makes us a definite pennant threat ... He'll help us where we need help the most." In 40 games with the Cardinals that season, he earned 11 saves but finished with a 1–4 record and his highest ERA to that point in his career (4.25).
The Cardinals placed him on waivers in September and he was claimed by the Cleveland Indians, who used him in two games that year.
In 1958, Cleveland manager Bobby Bragan used Wilhelm occasionally as a starter. Although he had a 2.49 ERA, none of the Indians' catchers could handle Wilhelm's knuckleball.
General manager Frank Lane, alarmed at the large number of passed balls, allowed the Baltimore Orioles to select Wilhelm off waivers on August 23, 1958. In Baltimore, Wilhelm lived near the home of third baseman Brooks Robinson and their families became close friends. On September 20 of that year, Wilhelm no-hit the eventual World Champion New York Yankees 1–0 at Memorial Stadium, in only his ninth career start. He allowed two baserunners on walks and struck out eight. The no-hitter had been threatened at one point in the ninth inning when Hank Bauer bunted along the baseline, but Robinson allowed the ball to roll and it veered foul. The no-hitter was the first in the franchise's Baltimore history; the Orioles had moved from St. Louis after the 1953 season.
