Macharoundtheclock, a mare who won more than $500,000 in her career and thrilled crowds with her patented 'Silky Sullivan' rallies, was retired from racing following her start Monday at The Meadows and will begin her career as a broodmare with a booking to Sweet Lou.

Tim Twaddle, who trained the six-year-old daughter of Mach Three-Summers Soul, said her owner, Seth Rosenfeld’s Birnam Wood Farms, actually planned to breed her last year to Sweet Lou, transfer the embryo and return Macharoundtheclock to racing. Unexpected complications prevented the mating from taking place, resulting in a prolonged layoff for Macharoundtheclock.

“She came back off her game,” Twaddle said. “She wasn’t winning at the top levels like she had been. I think they were waiting for her to hit the half-million mark to retire her.

“I knew my time with her was borrowed time, but I’m grateful for the time we had with her. It’s been a treat racing a horse like her. I’ll miss her.”

He said this retirement is final, as plans are for Macharoundtheclock to carry her foal.

Macharoundtheclock couldn’t write a storybook ending to her racing days, finishing seventh in a conditioned event. She completed her on-track career with 22 wins in 91 starts, 51 in-the-money finishes, $501,013 in earnings and a fine mark of 1:51.1 taken at Mohawk at three.

Rosenfeld and Twaddle have a concrete reminder of Macharoundtheclock in their barn. They’re partners with Don Tiger in a two-year-old half sister to the distinguished retiree.

In Monday’s $22,500 Filly & Mare Not Listed Preferred/Preferred Handicap Pace, Set Me Up overcame Post 9 with a second over trip that carried her to victory in 1:52.1 on a “good” surface. She was a half-length better than early leader Show Runner. Do Me Honor was third.

Dave Palone piloted the seven-year-old daughter of Shark Gesture-Moccasin Flight, who boosted her lifetime bankroll to $413,255, for trainer Ron Burke and owners Burke Racing Stable LLC and Weaver Bruscemi LLC.

Aaron Merriman and Palone each fashioned a triple on the 15-race card.
