Rose, who shot a 7-under 65 on Thursday to fly into the lead, maintained his one-shot advantage into the weekend. Bryson DeChambeau jumped into second, however, after his 4-under 68 on Friday. Those two are in the final pairing in the penultimate day.

Several prominent players are threatening at the Masters, including world No. 1 Scottie Scheffler, the defending champion.

It began with a dart -- a stretch that could ultimately redefine McIlroy's week and erase a horrendous 30-minute window Thursday evening where he carded two double bogeys that moved the 35-year-old from 4 under to even par, from flawless to flawed. From the first page of the leaderboard to among the masses on page Nos. 3.

"I played really good golf (Thursday) and I wasn't going to let two bad holes sort of dictate the narrative for the rest of the week," McIlroy said.
