Trinniberg, one of the top-rated 3-year-old sprinters in the country, tuned up for his role as the potential favorite in the Grade 1 King’s Bishop here later this month with an easy half-mile breeze in 49.49 seconds over the Oklahoma training track Friday.
Trinniberg had regular rider Willie Martinez aboard for the work. Martinez was in town Friday to ride It’s Me Mom in the Grade 2 Honorable Miss later that afternoon.
