Doral, Florida: World number one Rory McIlroy has urged property tycoon Donald Trump to toughen up the Blue Monster course after labelling the site of this week's WGC-Cadillac Championship "outdated".
Trump will complete his purchase of the Doral course in June and has hired top course designer Gil Hanse to improve the championship course.
After another day of low scoring at the elite event on Saturday, with the scoring average 70 on the 72-par course, the 22-year-old McIlroy said he hoped the work would see some harder challenges.
"It's a resort golf course. It was a tough test 15 years ago, but now it's just got outdated," McIlroy, who shot a 65 after blitzing through the front nine with six birdies, said.
"They definitely need to do something with it and it's great to see that Trump is taking over the place and he is going to do a good job with it, I am sure."
Englishman Justin Rose, tied for second with Keegan Bradley, agreed with McIlroy. "I think in its day, it was long but long isn't really a test for us anymore," Rose said.
"The greens have been soft this week and any time you put a quality field on soft greens, you are going to get close to the hole and make putts and birdies.
"The greens are somewhat flat. I think that is why there are a lot of putts made on this course. I think someone told me a stat today, I don't know how they measure the stat but it's the easiest putting course that we play. So, that's why the scores are low."
But, tournament leader Bubba Watson had a different view. "It's very challenging. Obviously, when you are playing good golf, someone is going to shoot a low score," he said.
"Next year, it could be really windy but somebody is still going to shoot under par, that's just how golf is."
Watson agreed the softness of the greens had assisted the low scoring and said the wind this week had also been helping the players. "Fairways are not as firm as sometimes, the greens are not as firm as sometimes.
"Obviously you can make it tougher and tougher but you can't make the 18th hole any tougher unless you just add another tee on the 17th green I guess.
"There are some holes that are really difficult, some are easy. Right now, the wind is playing into our hands on these par-fives, three of them are somewhat downwind, so everybody is scoring on those," he said.
