US CAPTAIN Steve Stricker asked American fans to not 'cross the line' in his bid to win the Ryder Cup this weekend.

Stricker, 54 years old, hopes for a 'rowdy atmosphere' at Whistling Straits, but doesn't want to repeat the unsavory scenes of 2016.

The last Ryder Cup held in America at Hazeltine was five years ago. Team Europe was subject to a torrent of abuse.

After hurling disgraceful insults at Rory McIlroy, a spectator was removed from the course.

Golf365 quotes Stricker saying on the crowd, "They'll shout." We hope they'll be pro-US.

"But, we also hope they don't cross that line, as we've seen at other Ryder Cups over the years.

It's going be loud. It will be loud, especially at the first tee. We are looking forward to it.

We need it. That backing is what we need. It is our home turf.

"We were in Hazeltine not too many years ago, and that got louder and a bit over the line at times. This is something we don't want."

In recent years, home advantage has been crucial. The hosts have won six of the seven Ryder Cups.

Padraig Harrington, European captain, is aware of the challenges that lie ahead for his team in Wisconsin.

He said, "Clearly, the home captain has a say in how the course is set up.

"And he's willing to do whatever it takes to make that setup work for his players. It has a huge influence on me.

"Historically, it was difficult to beat the US on their own style of golf course.

"And we have shown it's quite hard to beat us here in Europe if you choose one of our courses that's naturally suited for your games.

"It is all about choosing the best venue and then designing the golf course to fit your players."
