Star mare Winx loses her first foal

Australian racing superstar Winx lost her first foal overnight.

The owners, Peter and Patty Tighe's Magic Bloodstock Racing in partnership with Debbie and Paul Kepitis and Richard Treweeke, provided few details in a news release on Tuesday.

"Our thoughts and attention at the moment are on Winx ensuring that she remains healthy, as anyone in this situation would respect," they said in the release. "It is a traumatic time for a mother and those involved and Winx is now the centre of our attention following the loss of a beautiful filly this morning."

Winx was in foal to I Am Invincible, a Yarraman Park Stud stallion who was Australia's leading first crop sire in 2013-2014 and was a top sprinter during his racing career.

In Winx's five-year career, the 2011 Thoroughbred won 37 races, and she is the world record holder for the highest earnings and most Group 1 wins. Trained by Chris Waller, Winx began a streak of 33 consecutive wins on May 16, 2015. Her last race — and 33rd straight victory — was in the Queen Elizabeth Stakes in April of 2019.
