Rocca was the first Italian to play for Europe in the Ryder Cup, and remained the only Italian to do so until 2010, when Francesco Molinari qualified for the Ryder Cup held in Celtic Manor and Edoardo Molinari was a captain's pick. He appeared in 1993, 1995 and 1997, and had a 6-5-0 win-loss-half record, including 1 win and 2 losses in singles matches. That one singles win came in a crucial match against Tiger Woods in the 1997 Ryder Cup at Valderrama, which Rocca won 4 & 2 to help Europe claim the cup. The victory against Woods was one of Woods' first losses in singles play. His 53% winning record in the Cup is one of the best in European team history. During the 1995 Ryder Cup, Rocca made a hole-in-one on Oak Hill's sixth hole, only the third ace in Ryder Cup history. In 1999, Rocca almost qualified for the Ryder Cup again after he won the West of Ireland Golf Classic.
