Aurora went on to win the 1976 Copa Fraternidad by beating some of the best teams in Central America, including defending champions Platense,[5] thanks in good part to the attacking duo Pennant and René Morales each contributing with a tournament-high seven goals to the successful run.
Coach Hernán Carrasco Vivanco brought Pennant to Aviación for the 1977 season, and in his first year there, the striker scored seven goals in the league[7] and two in the domestic cup.
[10] Pennant's best season in Chilean football was his third (1979), when he scored ten league goals – seven of which came in the first seven matches, including a hat-trick against Everton de Viña del Mar.
Four years later, however, he helped Guatemala qualify to the 1976 Games in Montreal, where he started against Israel (0-0), played the last 15 minutes of a 1–4 loss against Michel Platini's France, and the match against Mexico (1-1).
Pennant also played in the 1974, 1978 (where he missed the final round in Mexico in October 1977 having migrated to Chile), and 1982 World Cup qualifying processes.
