Sruthan maintained his progress when landing his second Group Three victory in the Big Bad Bob Gladness Stakes at the Curragh on Sunday.
Paul Deegan's gelding signed off 2013 with a win in Tipperary's Concorde Stakes and began the new season on a high note.
Chris Hayes always had Sruthan (9-4 favourite) handily-placed as last year's winner Custom Cut and Cristoforo Colombo took the field along before asking the four-year-old to make his effort.
Wearing a hood for the first time, Sruthan pulled clear in the closing stages to win by a length and a half from Custon Cut, with Wannabe Better a close-up third.
Deegan said: "He did it well. I always thought he was going to be a better horse this year. He has grown and has huge depth. We'll stick to in and around a mile and he'll improve from that.
"He could go for a Group Two in France (the Prix du Muguet at Saint-Cloud) and there's the Lockinge Stakes (at Newbury) as well. We'll see how he is. I haven't killed him for today as it's a long season."
