Golf star Marina Alex will not compete in the LPGA Drive On Championship in Ohio this week after testing positive for coronavirus. 

The 29 year-old was tested as part of the LPGA’s pre-travel screening and now remains in self-isolation despite returning three negative tests since.

She said on Twitter: "Unfortunately on my official pre-test screening on July 21st I was detected positive for Covid-19.

"I am very fortunate that I have not experienced any symptoms of COVID over the last 9 days. 

“I know this virus has affected so many lives and it is not something I am taking lightly. 

"At the advice of my primary care physician I have remained in isolation while continuing a testing regiment which has successfully produced 3 negative tests in the last 7 days. 

“I have exhausted every resource possible to be able to compete at Inverness, however due to current CDC guidelines and the current protocols the LPGA has put in place for our safety my official clearance date does not allow me to compete this week.”

Alex started playing on the LPGA Tour in 2014 and won her first event two years ago at the Cambia Portland Classic.

She will next compete at the Marathon Classic in Ohio on August 6.
