LEXINGTON, Ky. &ndash; With the 2010 racing year now in the books, the sport&rsquo;s major publications are showing different sires &ndash; Giant&rsquo;s Causeway, Fusaichi Pegasus, and Malibu Moon &ndash; as the year&rsquo;s leading North American general sire, depending on how they count progeny earnings.\r\nThe discrepancies are due largely to how each of the three publications &ndash; Daily Racing Form , Thoroughbred Times, and The Blood-Horse &ndash; tally foreign progeny earnings. Neither Daily Racing Form nor The Blood-Horse counted earnings from Hong Kong, Japan, or the Southern Hemisphere in their sire lists. But Thoroughbred Times included earnings from 18 countries, with Japan, Hong Kong, Australia, and Argentina among them.\r\nAccording to Daily Racing Form &rsquo;s internal database and The Blood-Horse, Giant&rsquo;s Causeway was North America&rsquo;s leading general sire, though their earnings tallies differed slightly. Blood-Horse&rsquo;s total was $8,806,163, compared to $8,806,413 at the Form . Thoroughbred Times crowned Fusaichi Pegasus ($11,480,932). Both Giant&rsquo;s Causeway and Fusaichi Pegasus stand at Coolmore Stud&rsquo;s American division, Ashford Stud.\r\nThe Form &rsquo;s Leaderboard section uses a different set of criteria, ranking sires by their progeny&rsquo;s U.S., Canadian, and Dubai World Cup Day earnings. By that standard, the Leaderboard has Spendthrift Farm&rsquo;s flagship stallion Malibu Moon, sire of Life At Ten, as North America&rsquo;s leading general sire with $8,452,232. The Blood-Horse, incidentally, also produces a sire list for North American earnings only, and Malibu Moon also topped that list with $8,462,649.\r\nThere also were discrepancies on the leading turf sire lists, which are also swayed significantly by foreign results due to a preponderance of grass racing in other countries.\r\nDaily Racing Form and Blood-Horse statistics ranked Dynaformer as leading turf sire with $3,232,643.\r\nThe Form &rsquo;s Leaderboard statistics ranked English-based Medicean first with $4,069,650. That&rsquo;s due almost entirely to his sons Al Shemali and Bankable, who together earned more than $4 million in a single Dubai Grade 1 race this year. Al Shemali won the Dubai Duty Free, and Bankable finished second.\r\nThoroughbred Times did not list year-end turf sire rankings.\r\nThe year&rsquo;s other sire categories were more consistent, although the earnings amounts for category leaders sometimes varied. All three publications had More Than Ready as North America&rsquo;s leading juvenile sire, but his listed earnings differed. Daily Racing Form and Blood-Horse credited him with $1,970,306, while Thoroughbred Times listed $2,282,616.\r\nCongrats headed all three freshman sire lists with earnings of $1,660,269. All also listed Sadler&rsquo;s Wells as the leading broodmare sire but with differing earnings of $28,822,697 (Thoroughbred Times) and $15,998,657 ( Daily Racing Form and Blood-Horse).
