William Michael Conigliaro was an American baseball outfielder who played five seasons in Major League Baseball (MLB). He played for the Boston Red Sox, Milwaukee Brewers, and Oakland Athletics from 1969 to 1973. He batted and threw right-handed, and was the younger brother of Tony Conigliaro, with whom he was teammates on the Red Sox from 1969 until 1970.

Anthony Richard Conigliaro, nicknamed "Tony C" and "Conig", was an American Major League Baseball outfielder and right-handed batter who played for the Boston Red Sox and California Angels (1971). Born in Revere, Massachusetts, he was a 1962 graduate of St. Mary's High School in Lynn, Massachusetts. Conigliaro started his MLB career as a teenager, hitting a home run in his first at-bat during his home field debut in 1964. During the Red Sox "Impossible Dream" season of 1967, he was hit in the face by a pitch that caused a severe eye injury and derailed his career. Though he would make a comeback from the injury, his career was not the same afterwards.
