Hours before the Kentucky Derby, the European Classic season gets under way at Newmarket, where 15 3-year-olds are set to run one mile down a straight course in the English 2000 Guineas.
Aidan O’Brien has trained the Guineas winner four of the last six years and, in total, 10 times during his career, but while he’s represented Saturday by three runners, two among the favorites, his son Joseph O’Brien has a very live chance to win his first 2000 Guineas.
