Wilbur Forrester Wood Jr. (October 22, 1941 – January 17, 2026) was an American professional baseball pitcher. In a 17-year Major League Baseball (MLB) career, he pitched for the Boston Red Sox (1961–1964), the Pittsburgh Pirates (1964–1965), and the Chicago White Sox (1967–1978). A knuckleball specialist after joining the White Sox, he threw left-handed and batted right-handed.
Raised in Belmont, Massachusetts, Wood played several sports in high school and was signed by his hometown Boston Red Sox in 1960. He pitched sparingly for them over parts of four seasons before being traded to the Pittsburgh Pirates in 1964. Seldom-used by the team in 1965, he spent all of 1966 in the minor leagues before being traded to the White Sox. Wood, who had previously relied on a fastball and curveball, refined the knuckleball with the help of veteran knuckleball specialist Hoyt Wilhelm. He spent the next four seasons as a relief pitcher for Chicago. In 1968, he set a record (broken the next year) with 88 games pitched and was named the Sporting News American League (AL) Fireman of the Year.
The White Sox tried to trade Wood before the 1971 season, but an injury to starting pitcher Joe Horlen caused them to put him in the starting rotation. That season, pitching coach Johnny Sain suggested that Wood pitch with only two days' rest between starts, since knuckleball specialists do not put as much stress on their arms as other pitchers. Wood proceeded to lead the AL in games started from 1972 through 1975, starting a career-high 49 games in 1972. That season, he also recorded a career-high innings pitched (IP), breaking the live-ball era record of 376 IP set by Mickey Lolich of the Detroit Tigers just one season prior. He won 20 or more games for four consecutive seasons, leading the AL in 1972 and 1973 with 24 wins. In 1973, Wood also matched the 1916 record of Walter Johnson of a pitcher to win and lose 20 or more games in a season. Wood was an All-Star in 1971, 1972, and 1974.
After making 43 starts in 1975, Wood made only seven in 1976. A line drive off the bat of Ron LeFlore fractured Wood's kneecap in a game against the Detroit Tigers. Despite months of rehabilitation, Wood was "gun-shy" upon his return in 1977 and posted the worst earned run average among qualifying AL pitchers in 1978 (5.20). He retired after the season. Wood's 90 wins from 1971–74 were the most by a major league pitcher during that span. A lifelong New England resident, Wood held a number of jobs in the Boston area after his retirement from baseball.
Early life Wilbur Forrester Wood Jr. was born in Cambridge, Massachusetts, on October 22, 1941. His parents were Wilbur Sr., a wholesale foods employee, and Svea (née Swenson). Wilbur grew up in Belmont, Massachusetts, with his younger brother, Jimmy. The brothers were athletic and would play sports year-round. Wood attended Belmont High School, where he played in three different sports: baseball, as a pitcher; football, as the starting quarterback; and hockey, as a defenseman. His father, a semi-professional baseball player, taught him how to throw a knuckleball while he was in high school, but Wood relied on his fastball and curveball in actual games. Using just two pitches, he helped the baseball team win the state championship in 1959 (his junior year), and he finished his high school career with a 24–2 record. He also played for American Legion Post 99, winning 42 games.
According to Bill Stone, Wood's high school baseball coach, about 50 colleges wanted the prospect for one sport or another. Wood, however, wanted to play professional baseball, and he was drawing interest from the St. Louis Cardinals, the Milwaukee Braves, and the Boston Red Sox. The Braves paid for him to fly to Milwaukee for a tryout, where minor league director Roland Hemond was unimpressed. "He was a chubby little guy who didn't throw very hard. I watched him throw batting practice (and) couldn't get very excited." The Red Sox, however, hoped to boost ticket sales by having a hometown prospect turn into a sensation. They offered a significant bonus (reportedly from $25,000 to $50,000), and Wood accepted their offer. "I wanted to play for the Red Sox," Wood said of his hometown team in a 1989 interview, "but at that point I wanted the club that offered me the most amount of bonus money."
Professional career Boston Red Sox (1961–64) Wood began his professional career in 1960 with the Class D Waterloo Hawks of the Midwest League. He won his only decision in four games with the club, posting a 2.70 earned run average (ERA) before getting promoted to the Raleigh Capitals of the Class B Carolina League. With Raleigh, he had a 3–5 record and a 3.84 ERA in 13 games (12 starts). After the season, Boston added him to its 40-man roster.
In 1961, Wood attended spring training with the Red Sox for the first time. In his first inning of work, he struck out three San Francisco Giants hitters, prompting the Boston Globe to declare that he would have "spectacular success" in his career. Sent to the Class B Winston-Salem Red Sox to begin the season, he posted an 8–5 record with a 3.15 ERA, 103 strikeouts, 33 walks, and 99 hits allowed in innings pitched. Having trouble with their attendance numbers, the Red Sox promoted the young Wood to the major leagues in the middle of June. He made his major league debut at Fenway Park on June 30, allowing three hits and two runs while striking out three over the final four innings of a 10–2 loss to the Cleveland Indians. In the second game of a July 19 doubleheader, he made his first major league start (also against Cleveland), allowing three runs in three innings but not getting the decision in an eventual 9–8 defeat. He appeared in six games (one start) for the Red Sox, posting no record, a 5.54 ERA, seven strikeouts, seven walks, and 14 hits allowed in 14 innings before getting sent back to the minors in late July, this time to the Johnstown Red Sox of the Class A Eastern League. Wood did not pitch well there, losing seven of 10 decisions and posting a 4.62 ERA with 44 strikeouts, 15 walks, and 80 hits allowed in 74 innings.
Boston's Eastern League affiliation became the York White Roses in 1962, and Wood ranked among the league leaders by season's end. He finished tied for second in wins (15, tied with Dave McNally and Sonny Siebert behind Paul Seitz's 16), sixth in ERA (2.84), sixth in strikeouts (178), and third in hits allowed (198, behind Jay Ritchie's 209 and Richard Slomkowski's 202). His 219 innings pitched topped the league. Promoted to Boston in September, he made one start for the Red Sox on the 22nd, allowing three runs in innings but receiving a no decision in a 4–3 loss to the Washington Senators.
In 1963, Wood was one of the last pitchers cut in spring training. He opened the season with the Class AAA Seattle Rainiers of the Pacific Coast League, but after recording a 1.12 ERA and winning five of seven decisions, he joined the Red Sox in early June. Boston initially used him as a starter, but he lost four games and allowed 39 hits in 28 innings before getting moved to the bullpen in early July, where he spent the rest of the season. "The little sonofagun just couldn't throw hard enough," manager Johnny Pesky said. "But he wanted to pitch and tried his hardest." As a relief pitcher, he recorded a 2.45 ERA in innings pitched. In 25 games (six starts), he had an 0–5 record, a 3.76 ERA, 28 strikeouts, 13 walks, and 67 walks in innings pitched.
Though Wood began the 1964 season with Boston, he was given his outright release to Seattle in the midst of May after posting a 17.47 ERA in four games. Pitching coach Bob Turley thought he was not suited to success at Fenway Park. Spending the next few months in Seattle, Wood posted a 15–8 record, ranking among the league leaders in wins (tied for third with three other pitchers behind Bob Locker's and Ken Rowe's 16), ERA (2.30, second to Bruce Howard's 2.20), strikeouts (197, second to Al Stanek's 220), and innings pitched (211, seventh). He was also selected to the league's All-Star team. The Red Sox chose not to promote him in September, but Wood had his contract purchased by the Pittsburgh Pirates on September 6.
Pittsburgh Pirates (1964–65) Wood appeared in three games towards the end of the year with the Pirates, including two starts. On October 2, he held the Braves to two runs through nine innings, but the Pirates only scored two, and the game went to the 10th. The Braves loaded the bases against Wood, who then walked Woody Woodward to force in a run. Though it was his first complete game in the major leagues, he still had yet to win a game in parts of four seasons at the big league level.
1965 was Wood's first full season on a major league roster, though his appearances (all but one of which were out of the bullpen) were seldom. According to Gregory H. Wolf of the Society for American Baseball Research, Wood's "soft-spoken and amiable" nature led to a personality clash with the "brash" Harry Walker, who managed Pittsburgh. On August 29, he relieved Bob Friend in the sixth inning of a 2–2 game against the Houston Astros after Friend had allowed the first two hitters to reach base. Retiring all three men he faced, Wood was ultimately credited with the win, his first, after Pittsburgh took the lead in the seventh. In 34 games, he had a 1–1 record, a 3.16 ERA, 29 strikeouts, 16 walks, and 44 hits allowed in innings pitched.
In 1966, Wood was one of the first Pirates' pitchers cut from major league spring training. He said that he "thought about quitting baseball, but my wife encouraged me to try one more time." "I think he might have gone into the plumbing business with my father," his wife said. With the Class AAA Columbus Jets of the International League, he had what Wolf called "the hitherto best year of his career at arguably the most crucial point." Wood was named the International League's Most Outstanding Pitcher, leading the circuit in ERA (2.41), complete games (15), shutouts (8), and innings pitched (224). Additionally, his 14 wins tied for third in the league (with Billy Rohr behind Gary Waslewski's 18 and Ed Barnowski's 17); he lost just eight times, for a winning percentage of .636. Though the Pirates chose not to call him up after the year, his performance impressed George Maltzberger, a scout for the Chicago White Sox, who recommended the pitcher to general manager (GM) Ed Short. On October 12, the Pirates traded Wood to the White Sox for a player to be named later (ultimately Juan Pizarro).
Chicago White Sox (1967–78) Relief pitcher (1967–70)
When Wood arrived at spring training with Chicago in 1967, manager Eddie Stanky immediately informed him he would be the ballclub's mop-up man. Wood realized he needed to make a change to prolong his career. Since high school, he had experimented with a knuckleball, and one of Chicago's relief pitchers was knuckleball specialist Hoyt Wilhelm, who would later be elected to the Hall of Fame. "I went to him right away and asked him if he would explain more to me about the knuckler," Wood said. Wilhelm showed Wood how to throw good knuckleballs consistently. "You either throw the knuckleball all of the time or not at all. It's not an extra pitch," Wilhelm explained. Taking Wilhelm's advice, Wood's career took off, first as a relief pitcher, and then as a starting pitcher. With the White Sox, Wood became well known as a durable workhorse and was among the last pitchers to consistently throw well over 300 innings in a season.
