[4] Busher was an "exquisite" chestnut filly standing 16 hands (64 inches, 163 cm) high, noted for her intelligent head, beautiful stride and kind disposition.
She won in her racing debut on May 30 at Belmont Park, and returned two months later to record another win by four lengths.
Busher finished fourth in the Spinaway Stakes due to a poor start, but then won the Adirondack Handicap.
[3][7] For her final start of the year, Busher traveled to Laurel Park where she won the Selima Stakes by three lengths.
The field included future Hall of Famer Armed, who was considered the top handicap horse in the country at the time.
Busher tracked the early pace in third, then went to the lead at the top of the stretch and withstood a late charge by Armed to win by 1+1⁄2 lengths.
[3] Busher then returned to California where she lost the Will Rogers Handicap by a head to Quick Reward, to whom she conceded 11 pounds.
[7] On February 27, 1947 as part of a divorce settlement,[10] Mayer auctioned all his racing stock at Santa Anita track in an event that was broadcast over three radio networks.
Seattle Slew was inbred to both War Admiral and Baby League through Busher and her full sister Striking.
[5] Run in late February, it is an important prep race for three-year-old fillies on the Road to the Kentucky Oaks.
Physically though, War Admiral was on the small side and more closely resembled his dam Brushup and her sire Sweep.
His bloodstock advisor, Olin Gentry, convinced him that War Admiral was an exception, pointing to his resemblance to Sweep.
[4] Striking's modern day descendants include Kentucky Derby winners Smarty Jones and Super Saver.
[13] Baby League was a daughter of La Troienne, who, despite being winless in her own racing career in Europe, became perhaps the most important broodmare of the 20th century in the United States.
She produced two Hall of Fame inductees, Black Helen and Bimelech, plus several daughters who would go on to successful breeding careers, most importantly Big Hurry, Baby League and Businesslike.
