Jason Day rallies to earn share of lead at US Open

Jason Day has rallied from suffering vertigo on day two of the US Open to earn a share of the lead after the third round of the tournament.

The 27-year-old fell down on the course during his second round and was diagnosed from suffering from Benign Positional Vertigo as he finished the day on two-under.

However, Day battled through his symptoms and managed to record a two-under display of 68 at Chambers Bay to earn a share of the lead going into the final day of the tournament.

Jordan Spieth had a tough time during a round where he struggled with his putting as his four birdies were cancelled out by five bogeys, leaving him to card a round of one-over 71 to reach the end of Saturday's play on four-under.

The duo are joined in the lead by South African Branden Grace and America's Dustin Johnson, who both carded par rounds of 70, although a double-bogey by Johnson on the 13th hole cost him the outright lead at Chambers Bay.

One of the overnight leaders Patrick Reed had a day to forget as he put in a six-over performance of 76 to drop back into tied-ninth in the competition.

The chasing pack consists of Louis Oosthuizen – who carded the best round of the day at four-under – along with Cameron Smith, Shane Lowry and JB Holmes, who all sit on one-under, three shots off the pace.
