He was a home run hitter in a pro league in western Canada while wintering in Detroit, starring on the blue line of the Detroit Olympics of the CPHL. He decided to give up baseball around the same time the Detroit Falcons arrived in the NHL. They were quick to sign up the "local" star.

He returned home to Ottawa in 1932, to great fanfare. Returning to the blue line was a big reason for a quiet season.

McInenly would get into 43 NHL games with the Bruins over the next three seasons.
