Donegan, playing in her first tournament on the LPGA Tour, arrived at Pebble Beach after helping Europe reclaim the Vagliano Trophy in Scotland - but her clubs did not reach California until Tuesday and, when they did, her driver was broken.

However, despite having to source a replacement Ping driver, the 21-year-old ended up as one of six players tied for second place behind China's Xiyu Lin and Hyo Joo Kim of South Korea after her first-round 69.

Despite starting the back nine with consecutive bogeys, Donegan made five birdies and also holed out from 96 yards for eagle at the par-four 15th hole.

"It's like everything happens for a reason, the clubs were late and then the driver came and it was broken," she said. "All of a sudden I have no choice but to put this Ping driver in.

"Honestly I am delighted I did. The whole thing has been a bit surreal to be honest - nearly every five minutes it's like a pinch-me moment.

"It wouldn't be the first time I started bogey-bogey. For me to come back then and finish how I finished and play the rest of the round, I'm really proud of myself for that."

World No 9 Lin, the highest-ranked player without an LPGA Tour win, carded a four-under 68 at Pebble Beach and was later joined by Kim, who holed a 20-foot birdie at the 17th to draw level with her rival.

Lin registered five birdies in her round and just a single bogey, at the final hole, while Kim piled up four birdies over her first eight but then had a bogey at the next before recovering to become co-leader again.

Joining Donegan on 69 were fellow Irish player Leona Maguire - who birdied two of her final four holes - Nasa Hataoka of Japan, South Korea's Hae Ran Ryu and USA's Bailey Tardy and Allisen Corpuz.

England's Jodi Ewart Shadoff opened with a one-under-par 71, two better than compatriot Charley Hull and Scotland's Gemma Dryburgh.

Another trio of English players - Alice Hewson, Charlotte Thomas and Bronte Law - finished on 74, with Georgia Hall a further two strokes back.

Rose Zhang, the 20-year-old sensation who won on her professional debut earlier this season, also opened with a 74.

World No 1 Jin Young Ko made only one birdie in an opening 79, three worse than No 2 Nelly Korda, who put her opening drive over the cliff and onto the beach at the 10th.

Natthakritta Vongtaveelap of Thailand only made it through five holes of the first round before she was disqualified for her caddie using a rangefinder, which is allowed at other LPGA events.
