Big Rock, the Ace miler, moves to Maurizio Guarnieri as Yeguada Centurion transfer their horses, leaving Christopher Head as top owner.

Head bids goodbye to 22 horses, yet remains optimistic about the future. He looks forward to saddling a runner in the Qipco 1,000 Guineas.

The decision was communicated on Thursday morning, and the horses will be at Maurizio Guarnieri’s yard on Thursday evening. Ascot saw the colt thrive on soft ground, securing a six-length victory.

The four-year-old Rock Of Gibraltar colt has an entry in the Al Shaqab Lockinge Stakes at Newbury next month.
