NORTON, Mass. — The best players are on top of their games for the second straight week of the FedEx Cup playoffs.

Now there’s just a lot more of them.

Justin Thomas failed to birdie any of the par 5s on the TPC Boston and still turned in a tournament-best round of 8-under 63 on Sunday, giving him a share of the lead with Marc Leishman and setting up a Labor Day finish filled with some of the biggest names in golf at the Dell Technologies Championship.

One week after Dustin Johnson and Jordan Spieth produced a compelling duel on Long Island, they are part of a chasing pack at the TPC Boston.

So is Paul Casey, who now is 53-under par over his last 15 rounds of these playoff events. Jon Rahm couldn’t keep pace and lost his two-shot lead, though the 22-year-old from Spain remained just three shots behind.

Throw in Phil Mickelson, perhaps even Rickie Fowler, and a forecast that shifts from rain to sunshine, and it could be quite a show.

Thomas and Leishman were at 12-under 201, one shot ahead of Casey, two ahead of Spieth, three ahead of Johnson and Rahm.

“There is a heightened something to these playoff events that bring out certain champions for the most part,” Spieth said after finishing with two straight birdies to nudge closer to the lead. “It’s going to be a throw-down tomorrow.”

LPGA TOUR: Stacy Lewis came through for her hurricane-ravaged hometown – and ended a long winless streak.

The Houston-area player won the Cambia Portland Classic in Portland, Oregon, with her $195,000 in winnings going to the relief efforts. Her sponsor, KMPG, also pledged to match the donation.

The 32-year-old Lewis won her 12th LPGA Tour title and first time since June 2014, ending a frustrating stretch that included 12 runner-up finishes.

She closed with a 3-under 69 to hold off In Gee Chun by a stroke at tree-lined Columbia Edgewater.

CHAMPIONS TOUR: Scott McCarron won the Shaw Charity Classic in Calgery, Alberta, for his fourth PGA Tour Champions title of the season.

McCarron closed with a 3-under 67 to beat Miguel Angel Jimenez by a stroke at Canyon Meadows. McCarron opened with rounds of 63 and 64 to take a two-stroke lead into the final round.

The 52-year-old McCarron matched Bernhard Langer for the season victory lead and earned $352,500 to pull closer to the idle German star in the Charles Schwab Cup season standings.

EUROPEAN TOUR: Haydn Porteous shot a 3-under 69 to win the Czech Masters in Vysoky, Ujezd, by two strokes for his second European Tour title.

Starting two shots behind overnight leader Lee Slattery, the 23-year-old South African birdied six holes in the final round –together with three bogeys – to close at 13-under 275 at the Albatross Golf Resort near Prague.
