The 1955 Portsmouth Trojans not only won the school's 5th district title in 6 years, but at one point of the season they were ranked #1 in the AP Poll. PHS had an outstanding record of 20-4, only the 4th time in school history that a Trojan basketball team had won 20 games. In addition, it was the first time in Portsmouth's GOL history that the Trojans swept Middletown, Hamilton, and Springfield twice each. The only league losses that year were to Lima and Mansfield (Mansfield was a member of the GOL at that time). The only other loss in the regular season was to Columbus East.

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.
