Harnett doubles up as Summer Island resumes progress Having been amongst the winners earlier in the afternoon, jockey Paddy Harnett completed a double when partnering the Natalia Lupini trained Summer Island to win the PG Duffy & Sons Citroen Apprentice Handicap at the Curragh. A Dundalk winner on his stable debut in February, the Nigel O'Hare, Martin W White, Mark Devlin and Craig Bryson owned gelding proved slightly disappointing on his next start, before reaching the frame at Bellewstown on his most recent outing. Sent off a well backed 7/2f (from 5/1) here, Summer Island travelled strongly on the heels of the leaders before coming through to take over with a furlong left to run. Keeping on well inside the final furlong, the four-year-old had three lengths in hand of Comfort Line at the finish. Natalia Lupini said: "He was in good form coming here and, he came out of his Bellewstown race very well. The ground was probably a little bit soft for him the last day, good ground here today suited him better. "Paddy gave him a nice even ride, very straightforward. He picked up nicely and,galloped to the line. Hopefully, he'll be consistent in his grade, or even if he goes up a little bit, he'll still be consistent throughout the season for the owners."
