I remember discussing the question after his first few comeback games around the start of 2018 and concluding that he'd probably win one at somepoint because , if he got in position, his head would get him over the line. That's exactly what happened just last year at the Masters.
Given he's not 'old' in golfing terms just yet, I'd still say he has another at some point, probably another Masters or the open when it's a short course.
The biggest caveat to that is that he might simply give up playing before then, especially if he has pain or is rarely in contention.
