A southpaw pitcher and native of West Warwick, Rhode Island, LeFebvre had a nine-year playing career (1938–1944; 1946–1947).

LeFebvre entered baseball after graduating from the College of the Holy Cross.

In his major league debut on June 10, 1938, in his very first at-bat, Lefebvre hit his only MLB home run over Fenway's Green Monster.

In the early 1960s he also returned to the CCBL to manage the Dennis Clippers[4] and Chatham Red Sox.
