Calculator stamped himself as a first-tier Derby hopeful with an impressive win in Saturday’s Grade III, $100,000 Sham Stakes at Santa Anita, getting his first win in his fifth career try. Ridden by Elvis Trujillo, Calculator is trained by Peter Miller for Richard Pell of Rye, NY. Pell purchased the Florida-bred son of In Summation last April at Ocala for $132,000.
