Kennedy was born in Chicago. A line-drive hitter, he was blessed with a strong and accurate throwing arm. On June 22, 1937, the night before the White Sox signed him, Kennedy was working as a 16-year-old popcorn vendor at Comiskey Park during the World Heavyweight Boxing Title between Joe Louis and James J. Braddock. Kennedy debuted a year later, and became the starting third baseman in 1940. In 1940, he became the first teenaged major leaguer since 1900 to play 150 games in a season. After a break of three years to serve in the military during World War II, he returned, to play mostly in right field. In the 1948 midseason Kennedy was sent to Cleveland in the same trade that brought Pat Seerey to Chicago. Kennedy hit.301 the rest of the year and became a member of the last World Championship Indians team. His most productive season came in 1950, when he posted career-highs in batting average, runs, hits and doubles. The same season, he started two triple plays from the right field, matching Indians left fielder Charlie Jamieson's two triple plays of 1928. Kennedy was traded to the newly relocated Baltimore Orioles in 1954. On July 30, he belted the first grand slam for Baltimore against Yankees pitcher Allie Reynolds. In 1955, Kennedy was purchased by the White Sox and sent to Detroit in 1956. Released in April 1957, he signed as a free agent with the White Sox, for his third stint with the club. A month later, he was selected off waivers by the Brooklyn Dodgers, being released at the end of the season. Kennedy is the answer to the trivia question who was the last man to ever bat for the Brooklyn Dodgers. At 3:36pm, Kennedy flew out to centerfield on a 2-2 pitch with two out and no one on in the 9th inning of the last Brooklyn Dodger game ever played on Sunday, September 29, 1957 at Connie Mack Stadium in Philadelphia. Phillies defeated the Brooklyn Dodgers 3-2. Seth Morehead, a rookie lefthander was the pitcher for the Phillies. This game marked his major league debut as a starter and was the only time all season Brooklyn lost to a lefthander. They had been 6-0 against lefties throughout 1957.
Career as manager, coach and executive
Following his retirement, he was a scout and farm system director for the Indians, and manager of the Triple-ASalt Lake City Bees. During the 1962 season, Kennedy was named to the Cubs' College of Coaches. The Cubs had experimented with having a committee of coaches run the team on the field since 1961, as opposed to having a single manager. However, after the 1962 season ended with what is still the worst record in franchise history, owner Phil Wrigley named Kennedy as "head coach" for an indefinite period. After Kennedy led the 1963 Cubs to their first winning record in 17 years, he began to assert a more traditional managerial authority over the team. He served as head coach from 1963 until June 13, 1965, posting a 162–198 record. He served as special assistant to Cub general managerJohn Holland, manager of the Los Angeles Dodgers' Double-AAlbuquerque affiliate, and a coach with the Atlanta Braves until 1968. In 1968, when the Athletics moved from Kansas City to Oakland, Kennedy was their first manager. Oakland finished sixth in a 10-team league with an 82–80 record, a notable improvement from the 62–99 last-place 1967 Athletics. It was also the franchise's first winning season since 1952, when the team was still in Philadelphia. According to the 1972 book Mustache Gang, authored by Ron Bergman, on the last day of the season Kennedy walked into Charlie Finley's office, expecting an extension. Five minutes later, Kennedy had been fired. After that, he spent six years as director of player development and director of player personnel of the St. Louis Cardinals, and 1976 as a member of the Seattle Mariners' start-up baseball operations team preparing for the club's 1977 debut in Major League Baseball. Kennedy returned to the Cubs to succeed Salty Saltwell as general manager on November 24, 1976. His first act was to name Herman Franks as his first and only choice to replace Jim Marshall as manager. He resigned from the position and was succeeded by Franks on an interim basis on May 22, 1981. Rounding out his baseball career, Kennedy then served as a senior baseball operations executive for the Houston Astros and San Francisco Giants, assisting his former Cleveland teammate Al Rosen, then the president or general manager of those teams. In a 16-season playing career, Kennedy was a.254 hitter with 63 home runs and 514 RBI in 1,483 games. As a manager, he posted a 264–278 record in two-plus seasons. Bob Kennedy died in Mesa, Arizona, at age of 84.
