1. So now he's 21...and all grown up? Apparently that practice round Jordan Spieth played at Augusta National six months before his first Masters last year flushed all of the nerves out of his system. Spieth led the 2014 Masters at various points as a 20-year-old, and he is humiliating most of the rest of the field in this one. One day after just missing the tournament record with a first-round of 64, Spieth shot a 66 Friday. His two-day total of 14-under 140 break Raymond Floyd's 36-hole record of 141 by a stroke. In two days, Spieth has 15 birdies and one bogey. His score would be even lower if he hadn't missed three potential birdie putts of four, five and seven feet, the last coming on the 18th. But with a five-shot lead over Charley Hoffman and a seven-shot lead over the next closest in the field, he is the overwhelming favorite to win a green jacket at the age of 21.

2. Sorry, Charley: There were at least two things nobody would have expected in this Masters: 1) After two rounds, Charley Hoffman, the No. 63 ranked golfer in the world, would be in second place at 9-under par; 2) 9-under par is five strokes off the lead. Earlier this week at the Par 3 tournament, Hoffman scrambled to get Arnold Palmer and Jack Nicklaus to autograph two souvenir yellow flags so he could auction them off at fundraisers. Now his own signature may be worth something. He was 5-under for the day and 10-under for the tournament after consecutive birdies on 12, 13 and 14 but gave one back on the 18th hole. He was considered a likely candidate to fall off the leaderboard on day 2 but he's been so consistent you would have to assume now he's not going anywhere.

3. Phil is back: It was amusing that with all of the attention on Rory McIlroy, Tiger Woods, Bubba Watson, Spieth and others going into this week that three-time winner Phil Mickelson sort of slipped in through the back door undetected. It helped that Mickelson struggled last year, partly because of injury, and he didn't make the cut in Augusta for the first time since 1997. But he has looked strong this PGA season and this week. He was 2-under in the first round and 4-under Friday. He dropped four birdies on the back nine. At 6-under, he isn't likely to catch Spieth, but any suggestion that his days as a contender have been sufficiently smothered.
