Ortmann first represented Europe at the Mosconi Cup in the first competition in 1994 with the USA winning 16–12. The following year, Ortmann competed in the Continent's first win, and Ortmann was also on the winning side in 2002. The 2002 victory with Ortmann was described by six-time snooker world champion Steve Davis as "one of the best moments of my career". Ortmann competed in the team on eight occasions (1994, 1995, 1996, 1997, 1998, 1999, 2002, 2004), and was the non-playing captain in 2003. Ortmann's eight appearances is the fifth most of any European player.
