Jason Day will play on Saturday at the U.S. Open

Jason Day sported an entourage larger than the leaders and anyone else of note on the U.S. Open driving range as everyone craned their necks to gauge how he feels. On Friday, Day collapsed on the ninth green -- his final hole of the day -- and, after finishing up with a heck of a bogey from the bunker considering the circumstances, was diagnosed with vertigo.

If you didn’t know about his scary moment on Friday, nothing would seem amiss while watching him warm up. He looked like normal, pounding balls effortlessly while playing a right-to-left shape in front of a large crowd of media members. Instead of the usual one uniformed security officer, though, Day had four to keep people away.

Throughout Day’s normal warmup routine, pros stopped in to shake his hand, check on how he’s feeling and wish him well. There were smiles and nods, and Day seemed relatively at ease and comfortable following Friday’s scare.

Day will give it a go on Saturday and sits just three shots off the lead as the players near the top of the leaderboard prepare to tee off. Judging by the encouragement from the fans on nine Friday and the range Saturday, he’ll have a pretty vocal cheering section urging him along during the third round.
