Micheel, ranked 608th, led by one stroke after eight birdies and three bogeys, including one on the last hole of the Real de Golf de Sevilla course.
“I didn’t expect this,” said Micheel. “Yesterday in the the pro-am I didn’t make any birdies, and it wasn’t for lack of effort, I can assure you. … My iron play was good and I just managed myself well and gave myself a lot of opportunities.”
Jorge Capillo and Robert Rock and Danny Willett were tied with 68s.
The Memphis-based Micheel is competing on the European Tour under a 10-year exemption after winning the 2003 PGA Championship, his last victory.
He’s balancing invitations on the U.S. PGA Tour in an effort to regain full membership after forfeiting full playing rights at the end of last year.
