Two of the PGA Tour’s top stars in Phil Mickelson and Jimmy Walker have questioned the Tour’s drug policy in the aftermath of Scott Stallings being handed a three-month suspension.

Stallings, a three-time PGA Tour winner, has been suspended by the Tour after confessing to unknowingly taking a banned substance to help fight suffering chronic fatigue.

However the five-time Major winning Mickelson, who sympathizes with Stallings, has questioned the Tour’s drugs policy when the substance Stallings took is readily available over the counter to any citizen of the U.S.

“I give Scott a lot of credit for coming forth as he’s not trying to hide anything,” said Mickelson speaking to reporters on the eve of the Scottish Open.

Phil Mickelson questions the PGA Tour’s drugs policy.

“He made a mistake and he’s been very open about it.

“I like how we (PGA Tour) had a drug policy implemented over the last however many years to make sure that from going forward, we are all on a level playing field, even though I feel that was the case beforehand.

“But I don’t feel as though he’s (Stallings) saying the right that every other citizen has to take certain things over-the-counter to help their own physical health should be taken away just because we play golf.

“So he was in my own opinion trying to help his overall health doing something that every other citizen in the country has the right to do and it was taken away from Scott because he plays golf for a living and I don’t necessarily agree with that.”

Walker, and a winner twice this season in capturing the Sony Open in Hawaii and the Valero Texas Open, was more to the point.

Jimmy Walker also throwing up questions about the PGA Tour’s drug policy.

“It concerns me when a player gets prescribed medicine for an ailment and he’s suspended for violating the drugs policy,” said Walker.

“If it’s prescribed by a doctor you should be able to take it so I don’t think you should get into trouble for taking something that you need from a doctor.  It’s up to you and your doctor;  if your doctor has a better knowing and understanding what a patient needs.

They (PGA Tour) wouldn’t have known unless he (Stallings) failed a drugs test but he felt obligated to tell them and maybe that’s why the suspension is a little less than normal.

“We are all pretty much in the dark on what’s going on with all these suspensions and I think it needs to be brought to light a little more so we all have an understanding of what’s going on.

“There is a lot about the science of drug testing and seems like from I’ve heard, if you really want to do this, you give blood.

“So I don’t have a problem with whether you test urine or blood.  Test away!”

Rickie Fowler finds himself drawn into the controversy.

Reigning Players Championship winner Rickie Fowler also found himself drawn into the controversy and stating the issue all sounds a ‘bit iffy’.

“When it is something that is prescribed by a doctor then it sounds a bit iffy,” said Fowler.

“But then it’s about just being aware and maybe double-checking on some stuff.”

Mickelson, Walker and Fowler are among a big contingent of eight American-born players contesting the Thursday starting Scottish Open at the Gullane Golf Club to the east of Edinburgh.
