Petrushka shortens

Petrushka's position at the head of the betting for the 1,000 Guineas continues to strengthen following further support yesterday. William Hill cut Sir Michael Stoute's filly to 5-4 from 11-8 in line with Ladbrokes and Coral.

However, Alan Bailey has warned punters not to ignore his outsider Agrippina in Sunday's Classic. "I'd hope that Agrippina will finish in the first three on Sunday. She has got a turn of foot and there aren't many of the three-year-old fillies that we have seen who have got one, other than the favourite Petrushka."

Godolphin's China Visit has been all but assured of his place in the field for Saturday's Kentucky Derby after Laura Wohlers, trainer of Ifitstobeitsuptome, confirmed that her charge would not run.
