World number three Jon Rahm’s Saturday started with a hole-in-one and saw him take a six-stroke lead at the USPGA Memorial Tournament in Ohio.
It ended with the Spaniard’s withdrawal from the tournament after learning he had tested positive for Covid-19 as he left the 18th green.
Defending champion Rahm looked set to take home the top prize of $ 1.67million (£ 1.18million).
The PGA Tour said Rahm was notified as he was finishing his tour under the “Tour Protocols”.
A statement from the Tour said: “On the evening of Monday, May 31, the PGA Tour informed Jon Rahm that he was undergoing contact tracing protocols because he had come into close contact with a person who was HIV positive for Covid.
“In accordance with the Tour’s Covid health and safety plan, Rahm has been given the opportunity to remain in the competition and enter our tracing protocol, which includes daily testing and restricted access to indoor facilities. Rahm remained asymptomatic.
“Rahm tested negative every day, but his most recent test – which was taken after the end of his second lap (delayed rain) and before the start of his third lap – came back positive at around 4:20 p.m. KST. ‘Is while Rahm was on the golf course. The PGA TOUR medical adviser requested a confirmatory test on the original sample, which returned at 6:05 p.m. ET, and was also positive. “
Le Tour said Rahm must now self-isolate for 10 days.
“While this is an incredibly unfortunate situation, in 50 events since the PGA Tour returned to golf, there have only been four positive tests (including Rahm) in competition; Rahm is the first positive and asymptomatic case as part of Tour routine, contact tracing protocols, “the statement added.
Rahm’s hole-in-one came on the 183-yard par-three 16th hole as he completed a storm-delayed second round on Saturday morning.
This gave the reigning 26-year-old a two-stroke lead after two rounds over American Patrick Cantlay.
Rahm extended that to six shots after a round of 64 put him 18 under for the tournament, with Collin Morikawa and Cantlay in second.
After Rahm’s misfortune, the pair now hold a three-stroke lead over the chase pack.
