Li Haotong has shot a 10-under par 62 to lead after the first round of the Munich International Open as the European tour continued to allow players from the breakaway Saudi-backed LIV series to compete.

China's Li tied the course record on Thursday, finishing the round with his second eagle of the day on the par-five ninth hole after a big approach shot left him a four-foot putt.

"It's just been an incredible day for me. I didn't expect that because I spent a couple of weeks off in Dubai, which was hot, didn't practice much," Li said.

"It's just helped me mentally cool down a little bit. Low expectations, no expectations, just play golf and enjoy every shot."

Li is one stroke ahead of Daan Huizing and two clear of third-placed Nicolai von Dellingshausen.

Li was also tied for the first-round lead at his last tournament, the European Open, before fading to finish tied for 18th.

Former major winners Sergio Garcia, Louis Oosthuizen and Martin Kaymer and Australian Wade Ormsby were among the players who competed at the recent inaugural LIV event at Centurion to play.

They have all signed up to the Saudi-backed series and were competing in the first European tour event since the PGA Tour said it would suspend any of its players who join LIV.

Kaymer was the best of the LIV players on Thursday, finishing as one of six players tied for fourth on six under, four strokes behind Li.

Ormsby shot a four-under 68 to lie in joint-18th place while Oosthuizen was on two under and Garcia one over.

Germany's Maximilian Kieffer delighted the home crowd with an albatross on the par-five 11th, finding the pin with a 211-yard approach shot out of the rough, and ended the day on four under.
