Since his stellar season on the then Nationwide Tour in 2004, followed by an injury plagued season in 2005, a return to the Web.Com Tour in 2007 and often fighting to retain playing rights on the PGA Tour when he has had status, Walker has always looked a player capable of winning at this higher level.
It has been in only the last two seasons however that the 34 year old has begun to confirm the potential that he first displayed when winning twice on the Nationwide Tour in 2004.
Three months ago a disappointing finishing round at the Greenbrier Classic cost him victory and even today he appeared to be playing for second for much of the final round until the wheels began to fall off surprise leader Brooks Keopka.
Not that Koepka's effort to lead for so long in this event was a shock, after all the Floridian had won three times on the European Challenge Tour this season, but this was a chance to win and secure his future on the PGA Tour and over the closing ten holes or so the prospect of that victory became a little much for the relatively inexperienced tournament invitee.
As Koepka began to struggle, Walker was going to other way. Two birdies just before the turn had him within striking distance and as Koepka began to struggle on the greens Walker was flawless as he pursued a victory that would change his career.
In the end Walker won by two while Vijay Singh finished the event off strongly to finish runner-up. Considering Singh's best finish on the PGA Tour in 2013 prior to this week was 20th it was an encouraging sign for the now Champions Tour player.
Kevin Na, Scott Brown, Hideki Matsuyama and Koepka tied for 3rd one shot behind Singh.
It was a generally disappointing week for the Australasians although Danny Lee, back on the PGA Tour after a year on the Web.Com Tour, recovered from a slow start to finish 30th. Robert Allenby and Stuart Appleby both made the cut but finished well back.
The PGA Tour now moves to Las Vegas for the Shriners for Hospitals for Children Open.
