Struver, a 34-year-old who has won three times on tour, poured in six birdies and an eagle on Day 3 at Is Molas to move to 18-under-par 198.
He leads by one stroke over yesterdays leader, Gregory Havret (68) of France. Meanwhile, two off the pace sits Bradley Dredge, after the Welshman shot a 65 Saturday, while Spains Diego Borrego also carded a 65 to check in at 15-under.
For Struver, this is his best showing since he recorded a second-place finish at the Algarve Portuguese Open in April. Yet, while he tops off the leaderboard entering the final day, he knows that there is still much golf to be played.
Im not far ahead, Struver warned. One shot. I won a tournament where I was seven behind. Anything can happen.
Havret knows that concept quite well. After two early bogies threatended to ruin his round Saturday, he suddenly caught fire at days end, rolling in three birdies over his last four holes to get to within one of the lead.
I am confident about tomorrow, the 24-year-old rookie and former French Amateur champion claimed. One shot is not a lot, but there are a lot of players behind. It should be a very exciting day of golf.
It will undoubtedly prove to be that.
In addition to hungry youngsters like Havret and South Africas Trevor Immelman (who also shot 65 to reach solo fifth at 14-under), there are several other veterans in the mix who have gone some time without a win.
At three strokes off the pace, Spanish veteran Borrego has not tasted victory since his first win in 1996.
Likewise, Massimo Scarpa will be getting an extra dose of support on Sunday, as the local Italian player chases the second win of his career.
At 125th on the current Order of Merit list, Scarpa is also in need of a strong finish to move into the top-115, as those players will be given all-exempt playing privileges for the European Tour in 2002.
