Beginning his career as an outfielder with the Dodgers, he helped the team to the 1974 pennant with a .314 batting average, but a serious ankle injury the next year eventually led to his trade to the Cubs prior to the 1977 season. The Cubs moved Buckner to first base, and he won the National League (NL) batting title with a .324 mark in 1980. He was named to the All-Star team in 1981 as he led the major leagues in doubles. After setting a major league record for first basemen with 159 assists in 1982, Buckner surpassed that total with 161 in 1983 while again leading the NL in doubles, before feuds with team management over a loss of playing time resulted in his being traded to the Red Sox in the middle of the 1984 season.

During the 1985 season, Buckner emerged as the Red Sox stalwart first baseman, starting all 162 games and shattering his own big league record with 184 assists. Toward the end of the 1986 season, he was hobbled by leg injuries and struggled throughout the playoffs. Buckner’s tenth-inning error in Game 6 of the 1986 World Series against the New York Mets remains one of the most memorable plays in baseball history; it was long considered part of a curse on the Red Sox that kept them from winning the World Series, and led to years of fan anger and public mockery that Buckner handled graciously before being embraced by Red Sox fans again after their 2004 World Series victory.

After spending his last few seasons with the California Angels, Kansas City Royals, and a second stint with the Red Sox, Buckner became the 21st player in MLB history to play in four decades, ending his career with 2,715 hits and 498 doubles, having batted over .300 seven times with three seasons of 100 runs batted in (RBI).      -  Wikipedia by way of BING, copied entirely in 2020.
