Spaniard Eduardo de la Riva held a slender 1-shot lead after two rounds of the Open de Andalucía.
But there are plenty of good players within striking distance of the 29-year-old, who will have his work cut out for him over the weekend.
De la Riva leads the field on 8-under par after shooting a second-round 69.
One of the men behind him, Miguel Angel Jiménez, hopes to become the European Tour's oldest-ever winner.
The European Tour’s youngest ever winner, Matteo Manassero, is also only a shot behind.
This win, if it happens, would mean a lot to De La Riva who has been to European Tour Qualifying School nine times, the only time he made it through was in 2002, and he is only in the field this week because of his position on the Spanish Order of Merit last year.
“I played well off the tee but the key today were my shots to the green from 100 to 150 yards,” he said.
Jiménez is one shot behind along with Manassero, England’s Tommy Fleetwood, Irishman Damien McGrane and Pablo Larrazabal.
Among the group two behind on six under Eduardo Molinari and Oliver Wilson, a nine times a runner-up but never a winner on the European Tour.
