North American Jockey Club statistics for the 2013 breeding season show Into Mischief was the busiest stallion covering 210 mares.

Into Mischief (Harlan’s Holiday) stands at Spendthrift Farm in Kentucky.  He covered just 50 mares last year but his popularity spiked after siring first crop stakes winners Goldencents, Sittin At The Bar and Vyjack.

CashCall Futurity winner Into Mischief is also a half-brother to last season’s US champion juvenile filly Beholder (Henny Hughes) who has added three Group 1 wins to her tally this year.

His sire Harlan’s Holiday had the second largest book with 187 mares covered at WinStar Farm.  Spendthrift Farm’s Archarcharch also had a book of 187.  His first crop are foals.

Kitten’s Joy covered 184 mares earlier this year.  He has been in sparkling form this year supplying the Group 1 winners Admiral Kitten, Big Blue Kitten, Kitten’s Dumplings, Real Solution and Stephanie’s Kitten.

Ashford Stud resident Majestic Warrior, whose first crop yielded this season’s four-time Group1 winning three-year-old filly Princess Of Sylmar, covered 176 mares.  Ashford’s Irish Derby winner Cape Blanco, who was North America’s busiest stallion with 220 covers in 2012, was visited by 141 mares this year.

Overall, the North American Jockey Clun reported that 1,698 stallions covered 34,174 mares.  The number of mares bred was 3.4% down compared to last year.
