Finishing a head ahead of Owen Burrows' Albasheer, this was Jumby's sixth run of a busy season.
A third-placed handicap finish behind Creative Force, a subsequent Group winner, opened his campaign.
Pattern company could now be under consideration for Eve Johnson Houghton's colt but the Ayr Gold Cup remains a possibility too.
"We were thrilled with him, really pleased," Johnson Houghton said of the success at Salisbury.
"He's in the Ayr Gold Cup, but it depends on the ground whether we go there or not.
"He'd be quite well in because I imagine the handicapper won't be kind after that, and then we'll have to go up to Pattern class.
"I'm not in a hurry with him now, he's a big horse and he's had plenty of racing this year.
"He'll stay in training for next year and I think he'll be a lovely horse for next season."
Meanwhile, Johnson Houghton has yet to decide on Chipotle's next outing, with the juvenile sprinter currently entered in the Mill Reef at Newbury and the Middle Park at Newmarket.
The two-year-old's last outing was a ninth-place finish in the Group One Nunthorpe Stakes at York's Ebor Festival. It was a solid performance behind victor Winter Power, with Chipotle now resting in his paddock after a hectic campaign that began back in March.
Johnson Houghton said: "He has got a few things (to consider), he had a good few early entries.
"We're just giving him a week or two off, it was a tough enough race at York and then we will look at our options.
"He certainly wasn't disgraced, he was only beaten six lengths, he's run a lovely race.
"He's a really tough, genuine horse but again, he's had plenty of racing so he's having a bit of time off in the paddock, a week off to freshen him up, then we'll see where we go after that."
