Tiger Woods and 11-year-old son Charlie four shots off the lead at PNC Championship

Tiger Woods insists he is "Dad" first, team-mate second when it comes to playing alongside his 11-year-old son Charlie… but that hasn’t stopped them having an “absolute blast together” on the golf course.

Tiger and Charlie - Team Woods - were four shots back of the lead after the first round of a two-day exhibition event in Orlando, Florida, on Saturday.

Woods Jr and Sr opened the PNC Championship at the Ritz-Carlton Golf Club with a 10-under-par 62 that left them in a share of sixth place in a 20-team field consisting of major champions and winners of The Players alongside a family member.

"First and foremost, I'm Dad," Tiger said after the round.

"But there is that competitive spirit that Charlie and I both share, and we want to win, but also being competitive and being with each other and leaning on one another, it was an absolute blast."

Charlie Woods, the youngest competitor in the tournament's history and perhaps its most anticipated, quickly produced highlights reminiscent of the type his father delivered while collecting 15 major championships.

Team Woods will be paired with twice major champion John Daly and son Little John on Sunday.

Matt Kuchar and his 13-year-old son Cameron held a two-shot lead over Vijay Singh and son Qass while Australian Greg Norman and son Greg Jr. were a further shot adrift along with Team Lehman and Team Duval.
