Four days later, the Canadian beat Australian Mark Hensby by one stroke for his eighth PGA Tour win but first since February 2004.
It definitely restored some confidence, Weir said Wednesday.
The low-key Frys tournament begins a four-day run Thursday on the par-70, 7,125-yard Raptor course at the Grayhawk Golf Club.
Most of the PGA Tours big names are sitting out these Fall Series events, but for Weir, the tournament was a much-needed refresher course in winning.
To get that feeling again, to have to do something down the stretch, he recalled. I had to make a nice putt on 17 and to do it again on 18, had to make a great save. When youre able to do that, come through, it just reminds you that you can still do it when you need to and have to do it.
Weir hasnt won since the Frys event, but he did finish second twice'at the Memorial in May and the Deutsche Bank Championship in September.
Its been a pretty solid year, he said. I would say it hasnt been a great year, but its been steady. You know, this will be my last tournament on the tour to try to get a win and make it a very good year.
Weir has earned $2.8 million this year, 15th-best on the tour, making him the highest-ranked player in the field. The Frys.com Open, in its second year, has a $5 million purse. The winner gets $900,000.
Marc Turnesa, winner of last weeks Justin Timberlake Shriners Hospital for Crippled Children Open, withdrew from this weeks tournament.
The event is important for golfers trying to move up on the PGA Tour pecking order.
This is a big time of year for a lot of players, Weir said, whether its trying to secure their card, trying to get in the top 70 to get the invitationals, trying to win.
The top 125 on the money list earn exempt status on next years tour. Nineteen-time tour winner Davis Love III is at No. 125. But even if he slips below that spot, his career accomplishments allow him to enter any tournament.
Jeff Overton, 122nd on the money list, is out of the tournament after undergoing an emergency appendectomy at the Mayo Clinic in Scottsdale on Tuesday night.
The Frys event draws several players who live in the area in the offseason.
Bubba Watson needs to drive just 10 minutes to Grayhawk from his new Arizona home. He has taken some time off at the end of a long season that had him with three top 10 finishes.
Im just tired, mentally tired, mentally out of it, he said, and so three weeks off gave me some good rest.
Aaron Baddeley, who won the FBR Open just down the road from Grayhawk in 2007, has lived in Scottsdale for almost 10 years.
Grayhawk is where I pretty much started when I came over here, he said. So its great to be here. Its good to be around here with my family, everyone here. And my wife is three weeks away from a baby girl, so this is exciting times.
