INGLEWOOD, Calif. - Mast Track, winner of Saturday's at Hollywood Park, was transferred to trainer John Shirreffs on Sunday and will race in 2010, according to Mike Rogers, racing manager for Frank Stronach. Stronach acquired Mast Track in a private deal late last week from the Robert J. Frankel Trust. Frankel, the Hall of Fame trainer who died after a lengthy illness on Nov. 16, discussed the sale of Mast Track earlier this fall, according to a person familiar with the estate. Frankel bred Mast Track. Rogers said that no specific races have been selected for Mast Track but that he will stay in California. "Clearly, we'll race him, that's for sure," Rogers said. "We moved him to John Shirreffs. We actually made a deal that 50 percent of the earnings in 2010 we'll split with the Bobby Frankel estate." Rogers said that Mast Track is the first horse that Stronach has had with Shirreffs. Mast Track was trained since Frankel's death by his longtime assistant Humberto Ascanio. In the $100,000 Native Diver, Mast Track led throughout and won by 1 1/2 lengths over High Court Drama. The victory ended a nine-race losing streak for Mast Track, dating to the 2008 Hollywood Gold Cup. Mast Track, 5, has won 6 of 20 starts and $922,822. Earlier this year, he was second in the Grade 2 San Diego Handicap at Del Mar, losing by a nose.
