The four men atop the leaderboard through 54 holes of the US Open are three can’t misses and one, “Uh, OK.”
World No. 2 Jordan Spieth, No. 7 Dustin Johnson, and No. 10 Jason Day share the lead with South Africa’s Branden Grace, who is ranked 40th.
Day, who collapsed from vertigo during Friday’s second round, shot his second 68 in three days to be one of four players tied at 4-under, after starting the day in ninth.
Day was 2-over through 11, but fired four birdies over the last seven holes.
Spieth, who started the day tied for the lead, endured a very rock front nine to stay there. At 2-under through three holes, Spieth bogeyed 4, 5, 7, 9, and 11 before birdying 15 to finish at 1-over.
Grace and Johnson were tied for third to start the day and each shot an even-par 70 to remain there.
The quartet holds a 3-stroke lead over four more players tied for fifth at 1-under. The most curious of that bunch is South Africa’s Louis Oosthuizen, who started the tournament with a 7-over 77 and has shot back-to-back 66s since then.
On Day 1, Oosthuizen had five bogeys, two double bogeys and two birdies. In the 36 holes since, he has racked up zero double bogeys, four bogeys, 10 birdies, and an eagle.
Johnson rode his own roller coaster on Thursday; sitting 2-under at the turn, then spoiling it with a sequence of bogey, birdie, double-bogey on 11-13.
Grace was 2-under through 8, then bogeyed 9, 12, and 13.
Another six players are five strokes off the lead at 1-over including Day 1 co-leader Henrik Stenson, who has shot 74 and 72 since his opening-round 65.
