Michael Campbell is urging Lydia Ko to set her sights on emulating Tiger Woods' dominance of golf.
Wellingtonian Campbell, who won the 2005 US Open, is in awe of the 18-year-old Ko, describing her achievements as "phenomenal."
Ko became the third New Zealander to win a major title, after Campbell and Sir Bob Charles, when she claimed the Evian Open in France this week. She is the youngest winner of a golf major.
Campbell believes that after taking a small break, Ko can set her sights on the women's Grand Slam, and breaking retired Swedish star Annika Sorenstam's record of 10 majors titles.
"She needs to break even more records, set her goals even higher," Campbell told Radio Sport from Spain, where he runs his golf academy.
