Suneson's strong finish elevated the naturalized Spaniard to a 15-under-par total through 54 holes, good enough to tie overnight leader Bjorn for the top spot. Englishman Darren Lee is one off the lead at 14-under. German Bernhard Langer is just three back after firing a third-round 66.
For the third consecutive day, Suneson carded a 5-under-par 67. Win or lose this week, the 33-year-old should consider the trip to Munich, Germany a successful one. Last season, Suneson spent the majority of his time trying to earn his way back to the European Tour via the Challenge Tour.
The secondary tour proved to be beneficial to Suneson. He topped the Order of Merit and regained his primary tour card. He's currently 114th on the money list.
'I haven't been leading going into a last round on the full tour before,' said Suneson, who has suffered through thyroid problems and diabetes. 'But I won three times on the Challenge Tour last year and I'm going to draw on my experience and hope that's good enough to win tomorrow.'
Suneson, who was born in the Canary Islands and became a naturalized Spaniard four years ago, will be paired with Bjorn in Sunday's final pairing. Bjorn, currently fifth on the Order of Merit, has yet to win in 2000, but has earned a pair of top-3 finishes at the British Open and PGA Championship.
Though he's played, and proved himself, in bigger events than Suneson, Bjorn won't overlook his playing companion on Sunday.
'I had to make it from the Challenge Tour like Carl and I know he's a great player because you don't win the Challenge Tour without playing good golf,' said the Dane.
