Leading metropolitan combination Adam Durrant and Chris Parnham made a successful trip to the Great Southern, finishing with a winning treble at Percy Spencer Racecourse on Thursday. Durrant had five gallopers entered in the seven-race program and finished with three winners and two minor placings. Final Authority was a convincing winner in the second race, as was Tri For Us in race four and then Garage Days finished powerfully to claim race six. After going down as a short-priced favourite on debut, three-year-old Final Authority led from start to finish and gave a strong kick in the straight to win the Wellington and Reeves Maiden (1100m) by just under three lengths. Consistent mare Tri For Us settled midfield in the Albany Stockfeeds Handicap (1900m) before bursting down the centre of the track in the straight to grab the lead in the final 150m and win by just over two lengths. Garage Days produced a superb turn of foot in the Hahn Super Dry Handicap (1000m) to complete the treble for Durrant and Parnham, defeating Sir Snugalot by a short neck. Former jockey and now-full-time trainer Mitchell Pateman was overjoyed when Inflation won the Albany Race Club Life Members Handicap (1500m) by a neck. After sitting outside the leader in running, apprentice Holly Watson took Inflation to the lead at the top of the straight and they were not run down. Pateman said he was delighted to get a winner at his home track. “Always good to come home and get a winner, especially when Mum and the family are on course,” he said. “I thought he was in the right grade and was as good as I could get him. “It definitely means a lot. We nearly lost him when we first got him and he spent a bit of time at Baldivis Vets where they had to save him, so very special to get him back in the winners’ list.” The Roy Rogers-trained Catchya Catchya upset $1.70 favourite Soviet Spy in the Freight Lines Group Handicap (1900m), under the urgings of Chris Nicoll, to win by just over half a length. Currimundi was an impressive maiden winner in the opening event for trainer Steve Wolfe and jockey Natasha Faithfull while the Darren Taylor-trained Lucy Da Grey won race five for hoop Lucy Warwick, after being well supported in betting to jump a $4.20 favourite.
