The dual 2000 Guineas winner, who was forced to miss the Sussex Stakes following a downpour at Glorious Goodwood, ran with credit at York when finding only Ulysses too good in the Juddmonte International, on what was his first try at a trip beyond a mile.
Trainer Aidan O'Brien said: "We were very happy with Churchill. When we missed Goodwood, it just messed us up a little bit, but we we're very happy with the run. I would imagine that he'll come forward from it."
When it was put to O'Brien that he stayed the extended mile and a quarter well, he added: "I'd say he did. He was never a horse to wilt, anyway. I think the run will bring him forward.
"We're thinking of the Irish Champion, but we'll see how he is."
