The 1956 Portsmouth Trojans' district championship was the school's 6th in 7 years. PHS compiled a record of 16-7, with a 5-5 mark in the Greater Ohio League (at that time Mansfield was a member of the GOL). In the regular season, Portsmouth gave a double whipping of Ironton, beat Cincinnati Western Hills and Cincinnati Hughes, and also topped Columbus East. The win over Hughes was a nice way to start out the season considering that the Big Red had eliminated the Trojans in the regional final the year before.

After coming off 3 straight losing seasons for the first time in school history, the 1960 Portsmouth Trojans brought the basketball program back to prominence with an 18-5 season, winning a district title. The Trojans secured their first opening Greater Ohio League win in 4 years with a 64-40 triumph over Hamilton Taft. Portsmouth finished a very respectable 6-4 in the GOL, with a sweep of Middletown 68-58 and 62-52, and Hamilton Taft. The sweep of Middletown was particularly sweet in that the Middies had beaten the Trojans 9 straight times.
