Jordan Spieth will not be taking his foot off the gas and says he is going all out to win the Tour Championship in Atlanta.

The American tops the FedExCup standings heading into the final event of the PGA Tour Season but any one of the top five would land the $10million bonus if they win at East Lake, regardless of where Spieth finishes.

However, the Open champion wants to take the performances of his rivals out of the equation and has declared he will be playing to win the season finale once again.

"If you start playing for position that's when you take your foot off the gas pedal a little bit and that's not how we normally play," Spieth said at his pre-tournament press conference. "I'm comfortable at East Lake and I'm in a great position."

Spieth is also taking plenty of heart from his closing round of 65 at the BMW Championship last week.

"I was pumped to have the round I did on Sunday, to gain some momentum, to maintain the number one spot," he added. "I was a little bit off at the start of the week in my striking.

"But I feel pretty close right now to where I was in the first two Play-Off events. Things feel good. If this were a major championship, I'd be pretty pleased with how things are feeling."
