Boswell graduated from Calvert Hall College High School in 1963.
He drew the interest of several major league teams. One was the hometown Orioles who had ranked him and Wally Bunker as the two best pitching prospects in the country. Not able to afford giving each of them huge signing bonuses, the ballclub only signed Bunker after being disappointed by Boswell"s performance during his senior year.
Boswell eventually signed with the Twins for United States $15,000.
Even though the New York Yankees had offered the same amount of money, he decided that his chances to make the majors were better with Minnesota. After debuting with the Twins in 1965, Boswell pitched for the Twins in the team"s World Series loss to the Los Angeles Dodgers.
In 1966, Boswell"s.706 winning percentage (based on a 12–5 record) led the American League. Following a 1969 game against the Detroit Tigers, Boswell got into a fight with teammate Bob Allison and Manager Billy Martin outside the Lindell Air Corps bar near Tiger Stadium.
After knocking out Allison with one punch, Boswell was in turn knocked out by Martin, resulting in a cut that required 20 stitches.
During the American League Championship Series, Boswell lost 1–0 in 11 innings to Baltimore Orioles pitcher Dave McNally. He later revealed that he had suffered a career-ending arm injury during the game on a slider thrown to strike out slugger Frank Robinson in the bottom of the 10th. After being released by the Twins following the 1970 season, Boswell briefly played for the Detroit Tigers and the Baltimore Orioles during the 1971 season.
Boswell was the losing pitcher in Catfish Hunter"s perfect game on May 8, 1968.
Boswell died of a heart attack at his Joppatowne, Maryland, home on June 11, 2012.
