David Wilson Boswell (January 20, 1945 – June 11, 2012) was an American right-handed pitcher who spent eight seasons in Major League Baseball (MLB), all in the American League (AL), with the Minnesota Twins (1964–1970), Detroit Tigers, and Baltimore Orioles (both in 1971). He won twenty games as a starting pitcher during the 1969 season, the only time he achieved the feat during his major league career. "It felt like my shoulder went right into my jawbone," Boswell would tell the Fort Myers News-Press years later. "The arm would actually turn black and run all the way down to the elbow."
