1. Two Summers (IRE) – Total: 281.7
   Two Summers tops the list with the highest total rating. She ended last season with a 6f victory on this course on soft ground and has shaped well in all her three runs this season, ranging from 6f to an extended 1m. Given her latest conqueror’s subsequent success at Leicester, she is highly likely to be involved in the final contention.
2. Clotherholme (IRE) – Total: 267.7
   Clotherholme is second in total ratings. She is currently on a convenient mark and could have finished closer with a clear run at Beverley two weeks ago. Given these factors, she is definitely one to consider.
3. Mutanaaseq (IRE) – Total: 256.1
   Mutanaaseq ranks third based on total ratings. Although it’s been two years since his last win, he remains a threat off his current mark. His recent races have not gone as planned, finding trouble, but the trip and ground conditions are fine for him. We wouldn’t rule him out.
4. End Zone – Total: 235.5
   End Zone’s total rating places him fourth. While his recent form has been below par and his overall record is only 4-44, several of his past performances within the last year suggest he could be competitive.
5. Mr Strutter (IRE) – Total: 227.8
   Mr Strutter has only been successful once in his last 22 appearances but has won many races over the years. His reappearance was encouraging, and a return to 7f should not harm his chances. He could perform well.
6. Dreamcasing – Total: 225.8
   Dreamcasing has less mileage than the other horses and has the ability to win off his current mark. However, his habit of starting slowly, which again held him back on his reappearance, may be a concern.
7. Rain Cap (IRE) – Total: 220.5
   Rain Cap won over 6f here last August and ran well on AW two weeks ago, finishing strongly for fourth over 7f. He handles all ground conditions, suggesting he might perform well.
8. Obee Jo – Total: 210.8
   Obee Jo has five wins in total but none last season and his return at Doncaster wasn’t particularly impressive. While he’s well-handicapped, there are current reservations about his form.
9. Liberty Breeze (IRE) – Total: 205.4
   Both of Liberty Breeze’s wins came over this course and distance last summer, but she finished tailed off on her soft-ground return. Current conditions are offputting, which may hamper her chances.

In conclusion, Two Summers (IRE), Clotherholme (IRE), and Mutanaaseq (IRE) appear to be the top contenders based on their total ratings. However, positive comments on Mr Strutter (IRE) and Rain Cap (IRE) suggest that they could also perform well.
