Last week mixed satisfaction and disappointing in the Fair Grounds barn of trainer Steve Margolis. Cash Refund won the Gaudin Stakes on Saturday's card, and that morning, Risen Star hopeful Stay Put turned in a solid five-furlong workout. But Visavis had to be scratched from Saturday's Tiffany Lass Stakes after getting cast in her stall, and, even worse, promising debut winner What's New had to be put down after sustaining a leg injury in a half-mile work Jan. 14.\nWhat's New suffered a condylar fracture, and was euthanized after a surgeon determined his injury was irreparable, according to Richard Klein, one of the colt's owners.\nCash Refund, meanwhile, emerged in good order from his front-running victory in the Gaudin, Margolis said, and will be pointed to the $100,000 Duncan Kenner Stakes on March 27.\nStay Put, an impressive last-to-first allowance winner on Jan. 3, breezed five furlongs in 1:03.20 on Saturday morning.\nFriesan Fire's next start uncertain\nPlans for Friesan Fire's next start haven't been determined, trainer Steve Asmussen said earlier this week, but Friesan Fire looked ready to tackle a taller task after a sharp victory in last Saturday's Louisiana Handicap.\nWinning for the first time since the 2009 Louisiana Derby, Friesan Fire led all the way, setting a slow pace and turning back a challenge from General Quarters, a nice rebound from a third-place finish in his Dec. 3 allowance-race comeback from a long layoff.\n"I think he came out of it great," Asmussen said. "We're where we were hoping to be out of the allowance race."\nAsmussen said that the next start for 4-year-old filly War Echo is uncertain. War Echo, one of the leading 3-year-old fillies last winter in New Orleans, won the Daily Racing Form Distaff by more than three lengths Dec. 19 at Fair Grounds. She worked five furlongs in 1:01 on Tuesday in New Orleans.
