DAVID Hayes hopes to know before the weekend if emerging German stayer Sirius will join his Cups assault, repoerts Racing Network.

Hayes said he’s currently negotiating with the connections of Sirius, a last start Group 1 winner at Hoppegarten.

Sirius  ran third behind Protectionist, subsequent winner of the Prix Kergorlay at Deauville, at the start before he won the Group 1 Grosser Preis Von Baden (2400m) on August 10.

Hayes yesterday paid a late entry for Sirius for the Caulfield Cup.

“We should know in the next 24-36 hours, we are in deep negotiations, and if we get him, I want him to be in the Caulfield Cup,” Hayes said. “I took the liberty of paying up for him in the case that we do secure him.”

Hayes said Sirius, trained by Andreas Lowe, is a horse identified by bloodstock agent Rob Roulston, who foundAmericain for Gerry Ryan and Kevin Bamford.

He said Sirius, a northern hemisphere three-year-old, had competed against the best horses in Germany and more than held his own.

“He’s fully qualified for everything. I think of him as an Australian three-year-old winning the BMW,” Hayes said. “It makes him a pretty attractive horse.”
