Lee has made it no secret this season his goal was to make Nick Price's International Team - reserved for the top 10 players on the world rankings from outside the US and Europe. Lee is currently 10th on that list and looks like he'll comfortably hold his spot following this event.
Price also has two captain's picks to add to the International Team, which will contest the Presidents Cup in October.
New Zealand Golf high performance manager Gregg Thorpe said it was great to see Lee reaching such heights this year.
"It's fantastic to see Danny's progression over the years. He was such a prodigious young amateur talent and so many of our current amateurs have played with him, so it's great for those players to see him reach this level."
If he keeps up his current form Lee will also be gunning for two more big pay days at the BMW Championship (September 17-20) and Tour Championship (September 24-27).
The Deutsche Bank Championship is the second of four play-off tournaments held at the end of the PGA Tour season to find the FedEx Cup champion.
