And the Corkman, who displayed no ill effects ahead of his second British & Irish Lions tour next month, notched a full house of points in the first half as he added a 34th-minute drop goal to an earlier penalty, try and two conversions.
"Having been on the sidelines, I've a great hunger for the game now. I've been lucky with injuries over the last six or seven years - there's only really been three or four weeks that I've missed, here and there," said a jubilant O'Gara.
"Right now, the thought of going on the Lions tour really excites me. My injury was a bad one but all credit to Ger Hartmann (physio) for getting it right. I'm a lot more stable in my lower half."
