(CNN) -- Peter Hanson hopes he can hold his nerve and boost his chances of earning a place in Europe's Ryder Cup team by winning the Czech Open on Sunday.
The Swedish golfer takes a four-shot lead into the final round of the European Tour event, needing to win to move up from 15th in the points standings and into the automatic nine places ahead of the final qualifying tournament in Scotland next week.
He is being chased by 16th-placed Englishman Simon Dyson, who is tied for second in Celadna along with eighth-ranked Spaniard Miguel Angel Jimenez -- who co-designed the the Prosper Golf Resort course.
Hanson, who was given a special invite for the tournament on Monday, shot four-under-par 68 in his third round on Saturday, having been joint overnight leader with fellow leader Fredrik Widmark.
The three-time European Tour winner was caught at the top by Dyson and Jimenez before a burst of four birdies on the final nine holes, including one at the last to give him a 12-under total of 204.
"There's a little bit of a coincidence because the tournament I won in Sweden a couple of years ago was in the same week -- the week after the PGA Championship -- and I came home and had the same motivated feeling," the 32-year-old told the European Tour website.
"The last day will be a bit tense with what is at stake. Winning the event is a huge thing but even with the Ryder Cup there will be tension. Miguel is trying to hold on to his spot and stay in the team. Both me and Simon are trying our best to push our way on to it. So there will be some nerves tomorrow definitely."
Jimenez, who shot a day's best of 67, can all-but seal a place if he finishes in the top two -- but needs to play well as he cannot play at the Johnny Walker Championship at Gleneagles due to his nephew's wedding.
Dyson dropped an early shot but bounced back with four birdies for a 69 as he seeks to earn his first Ryder Cup outing against the U.S. in Wales in October.
"I think the front nine is the best I've ever played. If my putter had been hot it could have been something ridiculous," he said.
Fellow Englishman Ross McGowan, who is 11th in the Cup standings, faltered with a 73 that left him tied for 41st on 217.
Widmark slipped to equal ninth on 211 after a 74 featuring two double-bogeys and double, while Welshman Philip Price was fourth on 209 after a 69.
Ninth-placed Paul Casey, Padraig Harrington and Luke Donald are facing the prospect of requiring wild-card selections from Europe captain Colin Montgomerie after choosing to sit out the tournament.
Meanwhile, Indian golfer Arjun Atwal was caught at the top of the Wyndham Championship leaderboard by 2007 champion Brandt Snedeker on Friday.
World No. 450 Atwal followed up his course-record equalling nine-under 61 with a 67, while American Snedeker shot a flawless 65.
Lucas Glover, who needs a wild-card pick from U.S. Ryder Cup captain Corey Pavin after missing the cut at the PGA Championship, also shot 65 to be tied for third with fellow Americans John Rollins and Kevin Streelman on 129.
Streelman had been in the lead, but a late double-bogey saw him card 65, as did Rollins.
The tournament is the last before the start of the FedEx Cup playoff series, The Barclays, which features the top-125 players on the PGA Tour.
