ELMONT, N. Y. – I'll Have Another will have an additional rival in Saturday's 144th running of the Belmont Stakes as he tries to become the first Triple Crown winner in 34 years.

George and Lori Hall, the connections of 2011 Belmont Stakes winner Ruler On Ice, said Tuesday that My Adonis, most recently third in the Canonero II Stakes at Pimlico on Preakness day, May 19, would be lining up for the 1 ½-mile Belmont, the final leg of the Triple Crown. Ramon Dominguez is expected to ride.

According to Andrew Byrnes, the stakes coordinator for the New York Racing Association, Inc. (NYRA), the 3-year-old colt will be entered when post positions are drawn on Wednesday at 11 a.m.

The Halls will be looking to become the first owners to register back-to-back triumphs in the Belmont Stakes since Riva Ridge and Secretariat won in 1972 and 1973, respectively, for Meadow Stable.

“We came to this decision only a few hours ago,” said Lori Hall. “Over the last seven to 10 days he’s really shown to be eating well and to looking the part. We’ve just kind of kept in the back of our minds that this could be a possibility, and [trainer] Kelly [Breen] called us today and said, ‘I’m getting that good vibe.’”

Ruler On Ice upset last year's Kentucky Derby winner Animal Kingdom and Preakness winner Shackleford when he scored for the Halls and trainer Kelly Breen at odds of 24-1 in the Belmont Stakes.

The addition of My Adonis could bring the prospective field to 12.
