Swedish golfer Daniela Holmqvist had to think quick at the recent ISPS Handa Australian Open LPGA event. While taking her second shot from the rough on the fourth hole, she keeled over in pain after been bitten by a black widow spider. After local caddies had identified the suspect she realised that time was of the essence.

As Holmqvist's leg started to swell and the pain became intense, she made the quick decision to take matters into her own hands (she'd just been informed that a Black Widow bite can kill a child in as little as 30 minutes). She pulled a tee out of her pocket ("it was the only thing I had handy," she told Svensk Golf) and used it to cut open the wound so she could squeeze out the venom and keep it from spreading inside her body.
A clear fluid came out," she said. "It wasn't the prettiest thing I've ever done, but I had to get as much of it out of me as possible.
Amazingly, Holmqvist continued to play despite being in pain and shot 74. Which, unfortunately, was not enough to keep her in the tournament.
