Despite Marcus Fraser’s assertion that Baltusrol caters to a specific type of golfer, we saw the absolute transformation of the leaderboard into one of greater familiarity. Former champions Jason Day and Martin Kaymer are in the top-10, Henrik Stenson continued to impress and top golfers without a major moved into position to challenge for a first grand slam title. Five things became crystal clear on Friday, and we think you’ll agree with their importance.

Jason Day remembered that he’s Jason Day

We’ve been waiting for the defending champion to assert himself on the major stage in 2016, but it hasn’t happened. The Masters, U.S. Open and Open Championship came and went without a Day impact, but Baltusrol on Day 2 was different. The talented Aussie made birdies on 7 of 8 holes in the middle of the round to move from nine back of the lead to 7-under par. Unbelievably, after that unconscious run, Day failed to birdie both of the closing par 5’s. Rediscovering his major game, though, could prove quite disastrous for the rest of the field.

This is getting good! Our 2015 Champ is making it look too easy.#PGAChamp https://t.co/OPqK0hcz7q

That low round we suspected was out, was out there

Robert Streb birdied the 18th to shoot 63, tying the low score of all time in a major championship. He parred the 17th and bogeyed No. 16, so once again a 62 in a big-four event was within reach. Greens softened from morning rains certainly made his task easier, but Streb was lit as he moved into a tie for the top spot at Friday’s end. The 2014 McGladrey Classic was Streb’s PGA Tour coming-out party, but the Oklahoman has yet to follow up with another trip to the winner’s circle. Might it happen in New Jersey? Stay tuned.

What. A. Putt.

Robert Streb shoots 63.

Guys without a major might break through at Baltusrol

No, not Sergio Garcia. Maybe Hideki Matsuyama? How about Brooks Koepka? Does Rickie Fowler fit the bill? One guy with the ability to close under a variety of circumstances is Patrick Reed, who shot a 65 that might have been much lower, save for bogeys on the two 500-yard par 4’s on the front nine. The last four guys mentioned are within five strokes of the lead, so keep an eye on those final-hour twosomes on Saturday.

Dunked it.???? https://t.co/BFzz2yGvew

Speaking of remembering who you are

Jordan Spieth came back from the missing. If any golfer had more expectations placed on his 2016 performance than Day, it is certainly the 2015 U.S. Open and Masters champion (who also finished top-four at the Open and PGA last year, lest we forget). Spieth made five birdies in his outward 32, and only a late bogey on the 7th (he started on the 10th) kept him outside the top-10 heading into the weekend. If the Spieth putter remains torrid on Saturday, look for him to make a further dent in the leaderboard.

Jimmy Walker is bent on proving many people wrong

Including this writer. Walker, Texas Golfer followed his opening 65 with a 66 to preserve his spot at the top. Like Day, Walker failed to capitalize on the closing three-shotters, playing them in 1-over. True, he doesn’t have a two-shot lead on the field, but he does have the luxury of a non-intimidating pairing with Robert Streb on Saturday. The gallery will be large in Round 3, but it won’t be screaming “Strebber, Streba Strooey, Strebness” or something of that ilk.

All. Tied. Up.
