While playing for the Rebels in 1914, Lennox hit for the cycle on May 6, becoming the only Federal League player to do so. He also hit pinch-hit home runs in consecutive games on June 10 and 11, a feat that was not accomplished again until Victor Martinez of the Detroit Tigers did so against the Miami Marlins on April 4 and 5, 2016.
