Interesting pedigree but nothing up close that rings any bells from Thoroughbreds I know that have a "sport" reputation from any research I've done. Obviously he was bred for sport and is handsome. I did something similar along the same "lines" with a mare out of my foundation broodie and bred her back to Huntsman who is also her grandsire - pedigree below. He is Huntsman's last foal to date and was out of my foundation mare's last foal. He turned out super -- finished 9th out of 33 at his first eventing championships after only 3 or 4 events in his entire life! The two trainers that work with him adore him as does his current owner. Some history on your gelding?
He was bred by Allen Stock Farm here in California. That's what the ASF stands for. They did a lot of crosses by grandsons of Oklahoma Bound out of his daughters. It was either his dam or grand dam that used to give the breeders' kids bareback rides. They'd get on the fence, she'd wander over, let them get on her and ride around, and then go back to the fence so that they could get off. Their horses are known for amateur-friendly brains. Skipper had never been off the farm when we brought him in in August. He walked quietly off the trailer and into a paddock with far less fuss than I've seen from more experienced horses. He is a joy to work with--just wants to learn and work with people.
We went down there to look at horses and he was the one that stood out to both my trainer and me, though we didn't know that until we compared notes afterwards.
We had his aunt at the barn for awhile and another COTHer now owns her.
