Based on the total ratings, the top four contenders for the Weatherbys Ireland Greenlands Stakes at the Curragh are as follows:

1. Garrus (IRE) with a total of 533.3
2. Moss Tucker (IRE) with a total of 433.1
3. Art Power (IRE) with a total of 428.1
4. Ano Syra (IRE) with a total of 386.2

Garrus (IRE) holds the top position in the total ratings. Garrus made a strong return by winning the Abernant Stakes (Group 3) at Newmarket last month. While he might not be as consistent on a quick ground, his recent form is one of the best, suggesting that he could make a strong showing in this race.

Next is Moss Tucker (IRE). He is a useful front-runner who got back to his best recently with a Listed success at Naas and a commendable runner-up position in a subsequent race at the same venue. His very best form is with plenty of cut in the ground, indicating that the condition of the track could be a significant factor in his performance.

Third in the ratings is Art Power (IRE), who had a notable success at this venue, winning the last two renewals of the Group 3 Renaissance Stakes in an impressive fashion. Although his return at York last week after a gelding procedure may not have been as strong, his history at this venue and the potential for improvement make him a horse to consider.

Ano Syra (IRE) is fourth in the ratings. She showed a progressive form last term, with her career best performance being a runner-up in a C&D Group 3 in August. Though she could not match Art Power in the later part of the season, she may still have a say given a fully firing start after her 244-day absence.

Outside the top four in terms of ratings, but worth mentioning due to positive comments, is Twilight Jet (IRE). He is a dual Group 3 winner and despite finishing last in his two subsequent starts in Britain, he may have a potential to bounce back after his 11-month absence. His freshness could be an advantage as evidenced by him winning after a similar break last year.

In conclusion, the race appears to be a closely contested one, with Garrus (IRE) leading the pack in terms of ratings, followed by Moss Tucker (IRE), Art Power (IRE), and Ano Syra (IRE). However, Twilight Jet (IRE)’s fresh return could be an unpredictable factor in this race.
