Siyarafina was NOT supplemented for the French 1000 Guineas. Castle Lady WAS added to the field however and she is favourite at about 3/1 now.
The article I read reckoned Matematica would be favourite but her Boussac form has worked out quite poorly, with only Pink Dogwood winning a 10F listed race at odds-on to come from the late season Group 1. All other runs since (nine) have resulted in unplaced. The latest was Star Terms who finished 11th in our Guineas. Matematica won a maiden on seasonal reappearance and although she is lightly raced still, a maiden seems a strange prep for a Classic and that maiden has looked weak since. The runner up was 4th of 6 in a Listed race while all the others to run since have been beaten in maidens and a claiming race. Just doesn't look strong enough for me.
Matematica is 6/1 while Watch Me is 7/1. Watch Me beat Suphala last time in the traditional trial the Prix Imprudence but there was only a short head in it. Suphala needed her first start last season and she won her two races afterwards at a mile. Dropping to 7F for the Imprudence probably wasn't ideal and back at a mile with a run under her belt I expect her to reverse placings. East is 7/1 and the trainer says she has filled out from last season. Angel's Hideaway is set for a quick reappearance and she ran well at Newmarket. Like a few in that race, she looked as if not quite lasting. Runner up Lady Kaya is going sprinting now and I was a bit surprised by that because late in the Newmarket Guineas she looked to my eyes to see it out slightly better than Qabala to claim second. If Lady Kaya didn't stay, it makes a poor case for Qabala being a good stayer at a mile.
