Butch Harmon, her instructor, tweeted about the seriousness of Gulbis' diagnosis as well as LGPA golfer Se Ri Pak's, who withdrew from the tournament earlier in the week.
Just learned both SeRi and Natalie Gulbis putin the hospital in Singapore with Malaria . Hope they both will be ok— Butch Harmon (@43BH) March 1, 2013
But Harmon's report has been refuted by her agent, David Livingston, as well as the LPGA.
Natalie Gulbis' agent (David Livingston) says she wasn't hospitalized, doesn't have malaria, but was treated by doctor for flu-like symptoms— Randall Mell (@RandallMellGC) March 1, 2013
To reiterate earlier tweets, Se Ri Pak has flulike symptoms, not malaria. Natalie Gulbis is being evaluated in Singapore for illness. (Cont)— LPGA (@lpga) March 1, 2013
Gulbis shot a 3-over opening round of 75 on Thursday, while Pak didn't play in the first round.
