The Pittsburgh Shamrocks were a one-year wonder in the IHL all the way back in 1935-36. The team played at Duquesne Gardens, where they shared the ice with the already established Pittsburgh Hornets of the EAHL. The team would be coached by Sprague Cleghorn, who won two Stanley Cups in the 1920s with Ottawa. In their only season, the Shamrocks would go 18-27-1 and finish last in their division. The team lost an estimated $40,000 ($820k in today's dollars) and would fold before training camp the next season.
