One’s been there and done that. The other’s career is just taking off.

PGA Tour veteran Mark Brooks, 48, and rising sensation Rickie Fowler, 20, will be the two guys to chase come today’s final round of the 38^th annual Callaway Golf Pebble Beach Invitational after the two made moves in Saturday’s third round.

Brooks, winner of the 1996 PGA Championship and a two-time former Invitational champion (1992, 2002), climbed from a tie for third to the top of the leaderboard after a solid 3-under 69 at Spyglass Hill, while Fowler, formerly the No.1-ranked amateur in the world, leapfrogged nine players in the standings after a 5-under 67 at Del Monte Golf Course.

The two will both stand at a total of 7-under 209 entering today’s 18-hole finale at Pebble Beach Golf Links.

“I just played smart and my irons weren’t bad today,” said Brooks, whose day included four birdies and a lone bogey. “I never was really in a lot of trouble.”

A day after Friday’s weather-beaten rounds, Fowler too had a relatively easy time of it despite it being his first ever round on historic Del Monte. The former Oklahoma State star, who will compete at the PGA Tour Q-School Final Stage in two weeks, collected five birdies with zero bogeys.

“I had never played the course before,” said Fowler, who recently made a splash by finishing seventh in the Justin Timberlake Shriners Hospital for Children Open and second in the Frys.com Open. “My caddie walked the course earlier in the day. That helped a lot.”

Nipping on the heels of the two co-leaders will be fellow PGA Tour members Matt Bettencourt and Bryce Molder. The duo stands just a stroke behind following rounds of 72 and 70 at Pebble Beach, respectively.

Bettencourt played Pebble Beach numerously in the early parts of this decade while competing as an amateur on the Northern California Golf Association circuit. Molder competed in the 1999 U.S. Amateur at Pebble Beach.

“I’m not hitting the ball really all that well but I’m putting well which is half the battle,” said Molder, who finished 63^rd on this year‘s PGA Tour money list. “Anytime you get a chance to win something it’s fun.”

At three strokes off the pace are Champions Tour member and 2006 First Tee Open champion Scott Simpson and 2009 Nationwide Tour member Craig Bowden. Simpson had a stellar 68 at Spyglass Hill, while Bowden who re-earned his PGA Tour status for 2010 after finishing 22^nd on the Nationwide Tour’s money list, shot 73 at Spyglass.

Four behind with a three-day total of 213 are Champions Tour member Jim Thorpe (74 at Pebble Beach) and second round co-leader D.A. Points (75 at Spyglass), while a group of five players, including Monterey native Mina Harigae and 2001 Invitational winner Olin Browne, are five back.

Harigae, who will be a rookie on the LPGA Tour in 2010 after finishing first on this year’s Futures Tour money list, shot a 70 at Spyglass that included four birdies and two bogeys.

The cut (low 40) came at 7-over 223. Among those just making it were two-time defending champion Tommy Armour III, whose at 221 after a 70 at Pebble, and former Stevenson School star Rob Grube, who came in at 223 following a 78 at Pebble.

Among those failing to advance were five-time PGA Tour winner Billy Mayfair (226), Marc Turnesa (225) and Notah Begay III (228).

Brooks and Fowler, who will be in the final pairing, have never played together before.

“I know the golf course pretty well which can be good and bad,” Brooks said. “I know where you want to be and where you don’t want to be. If it’s windy, that’s where experience and local knowledge comes in. If it’s nice, guys can go low.”

Following Q-School, Fowler will two days later begin competing in the Shark Shootout in Florida. Invited by host Greg Norman, Fowler will be the youngest player to ever compete in the event. Brooks will be aiming for a record third Invitational victory.

No Champions Tour member has ever won the Invitational. The lone woman to ever win was Juli Inkster, who edged Brooks for the title in 1990.
