Scottie Scheffler turned the opening round of the FedEx Cup Playoffs into a formality Friday, ripping off five straight birdies to start his second round at the FedEx St. Jude Championship and coasting to a 9-under 61 that ties the course record at TPC Southwind.

The round, played through triple-digit heat that has hung over Memphis all week, put the world No. 1 at a commanding three shots clear of the field heading into the weekend, according to CBS Sports' live coverage of the round. It's the kind of front-loaded, low-drama domination that has defined much of Scheffler's season, and it arrives at the most consequential possible moment: the opening leg of the FedEx Cup Playoffs, where every stroke carries extra weight in the race toward the Tour Championship.

A Crowded Chase Pack

Behind Scheffler, the leaderboard reshuffled dramatically. Sudarshan Yellamaraju vaulted 33 spots up the field into a tie for fourth at 7-under after his own strong round, according to Golf Channel's reporting, part of a broader scramble among the field to keep pace with a scoring pace that heat and soft greens have made unusually low this week.

FIVE STRAIGHT BIRDIES TO OPEN, A COURSE-RECORD-TYING 61, AND A THREE-SHOT LEAD

For Scheffler, the round extends a run of playoff-opener form that has become one of the Tour's more reliable storylines: he now heads into the weekend at TPC Southwind as the clear favorite, with a cushion big enough to play conservatively if the Memphis heat and thick rough punish the rest of the field on moving day. A win would be an emphatic statement heading into the BMW Championship and the Tour Championship's season-ending shootout at East Lake.

Saturday's third round will show whether anyone in the chase pack — Yellamaraju included — can find enough birdies of their own to make it a contest, or whether Scheffler's Friday 61 has already settled the question of who lifts the trophy in Memphis.
