Sergio Garcia said his decision to skip last week's FedEx Cup play-off event is behind his charge at the BMW Championship.
With the Spaniard's spot at the season-ending Tour Championship virtually assured and an eye on the upcoming Ryder Cup, Garcia opted to bypass the Deutsche Bank Championship.
That decision appears to have worked wonders on a refreshed Garcia - 23rd in the FedEx Cup rankings - after the 34-year-old carded a six-under-par 64 for a one-stroke lead ahead of American Ryan Palmer at the halfway stage in Colorado.
A veteran on the PGA Tour, Garcia said playing last week would have had a negative impact on his preparations for the Ryder Cup, which tees off at Gleneagles on September 26.
"I would love to play all four tournaments on the FedEx Cup, but I knew that it wasn't going to be good for me to start with, I was going to get tired of it," said Garcia.
"It wasn't going to be good coming into the Ryder Cup. So, you know, if the Ryder Cup wasn't there I would have probably made an effort.
"But I didn't feel like that was the right thing for me to do and it was nice to spend some time with my girlfriend and some friends and in the Hamptons, we played a little golf, we enjoyed the beach, and we just had a good time."
