LEXINGTON, Ky. - Grade 1-winning juvenile Street Hero has retired from racing and will join the stallion roster at Vinery here, farm officials said.\nA Street Cry colt, he will stand for $12,500.\nStreet Hero underwent knee surgery after finishing third behind Midshipman in the Oct. 25 Breeders' Cup Juvenile. He is due to arrive at Vinery on Friday.\nStreet Hero raced as a homebred for his trainer, Myung Kwon Cho. After a third-place finish, also behind Midshipman, in the Del Mar Futurity, he won this year's Norfolk Stakes in September to earn his status as a Grade 1 winner. He leaves the track with 1 win, 2 seconds, and 3 thirds from 6 lifetime starts and has earnings of $419,360.\nStreet Hero is out of the Grade 3-placed Summer Squall mare Squall Linda and is her first stakes winner.P\nMarcavelly to stand in Ontario\nZayat Stables' dual Grade 3 winner Marcavelly has retired to enter stud in Ontario, Canada. A 4-year-old Johannesburg colt, Marcavelly will stand at John Burness's Colebrook Farms Stallion Station for $5,000.\nSobhy Sonbol, racing manager for Zayat Stables, said the lucrative Canadian-bred and Ontario-sired incentive programs were a major reason that owner Ahmed Zayat decided to send Marcavelly north of the border for his stud career. Sonbol also said that Zayat remains majority owner in the horse and plans to send mares to him.\nMarcavelly is from Johannesburg's first crop and is out of the Majestic Light mare Dark Jewel, who also produced stakes-placed Delong and is a full sister to Artie Schiller's dam, Hidden Light. He won the Transylvania Stakes and Hill Prince Stakes, both Grade 3, in 2007 and the Continental Mile Stakes in 2006. He placed in two other turf contests, the Grade 2 National Museum of Racing Hall of Fame Stakes at Saratoga and the Summer Stakes at Woodbine. He never tried dirt but did run second in the Woodford Reserve Bourbon Stakes at Keeneland when it was moved from turf to Polytrack.\nMarcavelly retires with wins in half his eight starts and $332,963 in earnings.\nBusiness slumps in England\nThe Tattersalls December mare sale concluded Thursday in Newmarket, England, with heavy declines in line with those seen earlier at breeding-stock sales in the United States and Ireland.\nThe four-day auction sold 610 horses for about $51,483,674, down 52 percent from last year's auction, when 762 horses sold. The average price, approximately $84,399, was off by 40 percent, and the median of about $19,293 was down 46 percent. Buy-backs were 32 percent, down from 33 percent in 2007.\nThe sale-topping filly was dual Group 1 winner Saoirse Abu, who sold to Sheikh Mohammed al-Maktoum for 1.95 million guineas, the equivalent of a little more than $3 million. A 3-year-old Mr. Greeley filly, she is likely to retire to visit Authorized in the breeding shed.\nEdmond Mahony, chairman of Tattersalls, noted that the 2008 catalog "lacked the extraordinary strength and depth of 2006 and 2007," but noted that quality horses, like Saoirse Abu, commanded high prices even in the recession.\nCongressionalhonor on the move\nGrade 3 winner Congressionalhonor will relocate in 2009 within Pennsylvania, from Maui Meadow Farm to Northview Stallion Station. First runners by the 7-year-old Forestry horse will hit the track in 2009.\nCongressionalhonor will stand for $3,500.\nHe is a son of the Quiet American stakes winner Quiet Dance and is a half-brother to 2005 Horse of the Year Saint Liam.
