Paul McGinley is refusing to get carried away despite playing himself into contention at the Open with a fine third-round 68 at Carnoustie.
McGinley has never finished in the top 10 at the Open
The 40-year-old carded four birdies as well as a bogey at the 16th and is three under par for the tournament.
"As a kid you dream of being in one of the leading groups on the last day of the Open," he said. "It's exciting.
"But there is a long way to go, this is a tough golf course and I am not going to get ahead of myself."
McGinley admits that his Ryder Cup colleague Sergio Garcia, who is leading the tournament, will be a hard man to beat on the final day.
I'm very aware of who he is and how he plays," said the Dubliner. "I hold him in the highest esteem and, having been in three Ryder Cups with him, I know how big a heart he has.
I'd like to shoot another 67 on Sunday and see how that leaves me
"It's a big ask to catch him, but I am now one of 10 to 15 players who have a chance to win."
McGinley's Ryder Cup partner Padraig Harrington also goes into the last day on three under after a 68.
Harrington grabbed three birdies in the first six holes and came back from a bogey on the 12th with another birdie at the next.
"I am happy enough," he said. "I got a good start and I played quite nicely from there.
"It's all about Sergio Garcia on the final day. He is showing the potential that we have talked about for years but we have to concentrate on our own game and play the right shots at the right time."
England's Paul Broadhurst admitted he was surprised to find himself tied for third after a superb 68 in the third round.
"At the turn I was thinking if I can hold it together at one or two over I would be quite happy," said the 41-year-old Midlander.
"But to finish like that was great on a seriously difficult stretch.
"It's one of the hardest back nines in golf and to come back in 31 is what dreams are made of."
Justin Rose was another early-starting Briton who enjoyed the best of the conditions.
Today is another step in the right direction, another little piece of confidence
The 26-year-old, who has not played in this event since 2003, looked out of contention with an opening 75 but hit back with a 70 on Friday and a 67 in the third round.
His card, which included six birdies and two bogeys, puts him on one under.
"I am in a position to mount a challenge as long as someone does not shoot something silly and reach eight or nine under," said Rose, who shared fifth place at this year's Masters and finished tied 10th at the US Open.
"Today is another step in the right direction, another little piece of confidence.
"I'd like to shoot another 67 on Sunday and see how that leaves me. You can't put a number on what might win because of not knowing how the weather is going to turn but I think five under overall might be thereabouts."
Fellow Englishman Paul Casey admitted his chances of a first major were probably over despite a creditable 69, which brought him back to the fringes of the leaderboard at one over.
"Tee to green I thought I played very well. Probably didn't make all the putts I wanted to," he said.
"I wanted to get back to even so I'm slightly disappointed I didn't. Going to have to be a bit closer than that."
