I heard Marty say that but I don't think he meant Zach would "never" win again. I took it as he thought Zach wouldn't ever win another major, or "big" tournament.
I could see him winning a hard, fast U.S. Open for another wager. Maybe even a couple of those. Probably no other majors, tho. He's got a Lee Janzen game, but is a better putter.

I see his career going similar to a Fred Couples, Davis Love lll type. Never going to be a dominant force, but a guy who makes the cut every week, usually finishes the year in the top 30 on the money list and wins the occasional tournament.
