AUGUSTA, Georgia (Reuters) - After largely managing to keep a lid on any lingering friction from the PGA Tour and LIV Golf drama during Masters week, bitterness and concern surfaced on Thursday following the ceremonial opening tee shots.

Although both sides have struck a conciliatory tone as officials work to hammer out an agreement to unify the sport, golfing greats Jack Nicklaus, Gary Player and Tom Watson were less diplomatic after launching the year's first major.

South African Player, 88, three-times winner at Augusta National, declared that loyalty must be rewarded and American Watson, 74, twice Masters champion, lamented the fractured state of the sport.

American Nicklaus, 84, owner of a record six Green Jackets, said the only solution was to have the best back playing against each other.

The frank views came a day after LIV Golf CEO Greg Norman, unwelcome at Augusta National, thumbed his nose at officials when he appeared at Wednesday's practice as a ticketed patron, the Washington Post reported, in a show of support for his 13 players in the Masters field.

Player was clear that if he was playing today he would not be in the forgive and forget camp.

"Anytime in any business whatsoever, not only in the golf business, there's confrontation, it's unhealthy," Player said. "You've got to get together and come to a solution. If you cannot, it's not good.
