Harmon helped the Bullets cap off an undefeated dual-meet season with wins over Dickinson and Franklin & Marshall. He swam on both winning relays, including the meet-clinching 200-freestyle relay, in a 109-96 victory at Dickinson, then contributed to four victories in a 186.5-74.5 win over F&M. Versus the Diplomats, Harmon won the 100-backstroke (52.22), the 200-backstroke (1:55.41), and the 200-IM (2:00.53), and he also swam the opening leg of the Bullets' victorious 200-medley relay team (1:36.34) as Gettysburg finished 9-0 and 6-0 in the Centennial Conference.
