The Cheveley Park Stud-owned pair of Echelon and Nannina feature among 10 declared for Saturday’s Kingdom Of Bahrain Sun Chariot Stakes at Newmarket.
The first-named Sir Michael Stoute-trained runner won her first Group One race in the Matron Stakes last time and will attempt to double up, while John Gosden’s Nannina will be chasing a third win at the highest level.
Falmouth Stakes heroine Simply Perfect heads the opposition along with Pam Sly’s Speciosa, who has failed to score since winning last season’s 1000 Guineas.
Chris Wall runs Wake Up Maggie, while David Elsworth and Mick Channon rely on Barshiba and Majestic Roi respectively.
Darrfonah, Whazzis and the Peter Makin-trained Harvest Queen complete the line-up.
The latter has been targeted at this high-profile prize since repelling Smart Enough by a length and a quarter in the Superior Mile at Haydock.
Makin said: “She’s been improving and it was a really good effort last time. It’s obviously a very hot race but she is entitled to have a go at it.
“There weren’t any other Group Two or Three fillies’ races to go for and if she can get in the shake-up, it would be very nice.
“She wouldn’t want extremes of ground so I think Newmarket should be perfect for her.
“She’s won on good to firm before but she ran a good race at Epsom behind Echelon on good to soft, so she’s quite versatile.
“She did it very nicely at Haydock so we’re keeping our fingers crossed – she seems in good order.”
