Victor Espinoza Tabs Tom Knust As New Agent Sponsored by: Hall of Fame jockey Victor Espinoza Victor Espinoza has hired Tom Knust as his new agent. The Hall of Fame member and three-time Kentucky Derby winner who celebrates his 49 th birthday May 23 parted company last Saturday with Brian Beach after a historic eight-year run. For more than three years, Beach's priority has been maintaining vigilance on his wife Lotta's recovery from an accident on a horse, which in part diminished his time representing Espinoza, who opted for a full-time on-track presence now that he's fully healthy and life is returning to a degree of normalcy with the pandemic on the wane.
