Roger James is pondering his next move with his highly-regarded filly Rondinella after she suffered a cardiac arrhythmia when tailing the field home in Saturday’s Gr.3 Desert Gold Stakes (1600m) at Trentham.

“She did fibrillate and it hadn’t converted back when she left the races, but she was vetted at six o’clock the next morning at Otaki and it was back to normal,” the Cambridge trainer said.

“I’m not sure if she will run in the Sir Tristram next, we’re working through that process.”

Meanwhile, James confirmed his last-start Gr.3 Trentham Stakes (2100m) winner Von Tunzelman will step out next in Saturday’s Gr.3 Windsor Park Stud City of Auckland Cup (2400m) at Ellerslie.
