Australia's Aaron Baddeley is just two shots off the pace with 18 holes to play in the PGA Tour's Barracuda Championship.

The 41-year-old shot a third-round three-under-par 68 at Port Royal on Saturday to sit at 16 under along with Taiwan's Kevin Yu (67).

Baddeley birdied all three par-5s, picked up two more shots on the front nine but bogeyed the par-4 sixth and 15th.

"I hit my irons really well. I feel like I hit most of the greens. I think I only chipped twice, I mean, that made it nice," Baddeley said.

"It feels like it's the right spot to be, to be honest. I feel like my game's been in the spot to be in this position for a while and it's just nice to be here, be back having a chance to win.

"That's why we practice, that's why we play ... hopefully we can just keep building on it tomorrow and hopefully come up the last with a chance to win."

Baddeley and Yu trail co-leaders Seamus Power (65) and Ben Griffin (66).

Irishman Power holed a 30-foot birdie putt on the daunting par-3 16th and made a 12-foot birdie on the par-5 17th to atone for his lone mistake, a double bogey on the par-3 13th.

"I knew I had to get birdies before 11," the 35-year-old world No.48, and highest-ranked player in Bermuda, said.

He made four in a row early and was six under for the day until a missed green and bad chips led to a double bogey on the 13th.

"One mistake. The wind drifted it a crazy amount," Power added.

"But I was able to hang in there and it puts me in a good spot going to tomorrow."

Power has one PGA Tour victory, the Barbasol Championship in Kentucky last year. He would love nothing more than a win for a strong early start to the PGA Tour and to assure his spot in the Masters.

For American Griffin, even more as at stake.

He gave up on the game a few years ago and was working as a loan mortgage officer when he was inspired playing in a member-guest, and the members put up money for him to Monday qualify into a Korn Ferry Tour event.

That was the start of baby steps -- making it through Korn Ferry Tour qualifying, and then last year earning his full card onto the PGA Tour.

A victory Sunday comes with a two-year exemption.

Ben Crane, whose last win was in 2014, started the third round with a one-shot lead but a 73 has him six off the pace in equal-ninth.

Sydneysider Harrison Endycott (70) is tied for 13th at 11 under, Victorian Cameron Percy (71) sits at eight under, with another Aussie in Greg Chalmers (76) at one under.
