Mark Newnham is hoping his four strong group can get the job done at Sha Tin. Mark Newnham is four strong for Sunday’s Classic Mile at Sha Tin and hopes his squad of Invincible Ibis, Infinite Resolve, Crimson Flash and Winfield can get the job done as he goes for back-to-back wins. “He’s maintained his form since his last run; he’s unbeaten since he went up in distance to the 1,400m and beyond,” said Newnham. “I thought his last win was his best, as he carried top weight and had to make a long run. “I think this year is a stronger race than last, there’s a lot of horses in form going into it.
