Enricher

Trained by the partnership of William Muir and Chris Grassick, Enricher comes from a yard that has sent out 21 winners this season — a healthy tally that suggests this isn't a team scraping around at the bottom end of the sport. They clearly know how to get a horse ready to win, which makes Enricher's return from a seven-month absence one of the more interesting storylines heading into the new campaign.

That layoff is the big question mark. Seven months is a long time, and horses returning from a break can take a race or two to find their best form. The most recent run before the break was a win, though, which means Enricher heads back to the track on a high note rather than needing to prove something. Whether the yard has timed this comeback well is what everyone will be watching.
