Calculus won the Jamaica St Leger by 6-3/4 lengths at 7-1 odds. It was Shane Ellis's 21st Classic triumph. Calculus is bred by Sensational Slam out of the Bernardini mare Trinket. The colt is expected to be favourite for the August 6 Jamaica Derby. It's Ellis' fifth St. Lege success and trainer Gary Subratie's second in a row. He's also won with trainer Chevan Maharaj's colts Supreme Soul and The Chosen One. She's a Wonder came third.
