Under the care of her new trainer, J. Larry Jones, Havre de Grace made her four-year-old debut in the Azeri Stakes on March 19 at Oaklawn Park in Hot Springs, Arkansas, with a victory over her archrival, Blind Luck.

Her Woodward victory was followed by the October 1 Grade I Beldame Stakes at Belmont Park in Elmont, New York, in which she scored by 8 1/4 lengths over eventual Breeders' Cup Ladies' Classic winner Royal Delta.

However, she fell short in her attempt to join Zenyatta in becoming only the second female racehorse to win the richest horse race in North America, finishing fourth behind the winner, Drosselmeyer.

Sweezey explained, “Having a mare like Havre de Grace in [Mandy Pope's] broodmare band, she is looking forward to trying to make money with the horse and maybe even racing a few out of her, and having that ilk of genetics.

With that being said, when I presented [Irish-based] Galileo to her, we talked about it at length, and she came back and said, ‘You know, it makes perfect sense from a business standpoint, but for me, I want to be able to come to the farm and pet my mare that I paid $10-million for, and I want to feed her carrots and watch her babies be born.

Wayne Sweezey, who boarded Havre de Grace at his Timber Town Farm, confirmed that the 16-year-old mare hemorrhaged multiple times, and died after producing a colt by Into Mischief the afternoon of April 28, 2023.
