Trainer Phil Humann sounded a warning to his rivals ahead of Keysbrook’s assault in the Listed Belmont Guineas (2000m) on Saturday.
Humann believes Keysbrook, who holds a record of one win and ten placings from 18 starts, is poised to land a breakthrough victory.
Humann is confident his daughter of So Secret has the class edge after a string of top efforts behind glamour filly, Delicacy, earlier this year.
Keysbrook met Delicacy on four occasions for three placings in the WA Derby (2400m), WA Oaks (2400m) and Ascot 1000 Guineas (1800m).
Punters have rallied behind Keysbrook, installing her favourite, after a fast finishing fourth to Tradesman in last Saturday week’s Belmont Guineas (1600m).
“She has been up a while but is going as good as when she ran second to Delicacy (2400m) in the WA Derby,” said Humann on TABradio.
“I can’t get her any fitter, she has worked well, looks good, will appreciate the step up to 2000m and I can’t fault her.”
Humann rates Cosmic Storm, from the powerful combination of trainer, Grant Williams and owner, Bob Peters, as the biggest threat to, Keysbrook, if the filly can handle a rise in grade.
The daughter of Street Sense, who is chasing a winning hat trick, burst into contention when she accelerated from the tail of the field to defeat Quintessence over 1600m at Belmont on June 27.
“She will have to be in Delicacy’s class to really beat her (Keysbrook) over 2000m,” said Humann.
“She has won her last two starts and although the fields haven’t been strong she is winning.
“All of Bob’s (Peters) are pretty well bred so she will be hard to beat.
“Dancing Express goes well and is also a chance.”
Keysbrook, to be ridden by, Peter Knuckey, from barrier two, is rated a $2.60 chance.
Cosmic Storm, drawn in barrier eight for inform rider, Peter Hall, is at $43.10.
Dancing Express, in the hands of Jason Whiting from gate ten, is $3.50, the only other runner under double figure odds.
