Jason Day thinks Jordan Spieth is right to be concerned by the form he is in and the fact he leads the world rankings.
Day has won three events this year, the latest of which was a wire-to-wire victory at the Players Championship.
Spieth has admitted the Australian's dominance and the gap he had opened at the top of the rankings bothered him.
The world number two bounced backed by winning the Dean & DeLuca Invitational, and Day is not surprised to see his impressive displays motivate his counterpart.
"I heard a couple of weeks ago that it bothered Jordan that I was winning tournaments and have the number one spot in the world - and it should," said Day.
"It should bother guys who are competitive and want to stay on top as well. There's nothing wrong with being bothered by that.
"I hope it motivates them just as much as it motivates me to see other guys on top of the world winning tournaments. That's just how some guys are pushed.
"I know I'm pushed that way as well when I see Rory [McIlroy] or Jordan on top of the world. I want to do that as well. So it's great to see how they've responded so quickly."
Day will be aiming for a fourth title of 2016 at the Memorial Tournament in Dublin this week, and he is expecting nothing less than a challenge to win.
"I'm expecting myself to play well each and every week now just from the sheer hard work I'm putting into it and the preparation I'm putting in each week before the tournament," he added.
"So it comes as a little bit of a surprise if I play bad because I'm not expecting to do that."
