Amy, Derby and Gerchgo should weigh in on Orb's success as a sire.  He has not produced those big winners, except that Larry Jones' trained Woah Nellie and a couple others have done nicely.  His dam side with Phipps bloodlines and also the links to SA lines would be an incentive for Uruguay to consider him.

Well crap! I pray for him as well!

He looks great, and doing good with runners, especially the last 2 years!

He has had a good life at stud and getting better mares

Of course they will. Coolmore not likely to stop unless they become less desirable
