When you see Pepperdine University alum Katherine Zhu on a golf course, she's not just there to show Collin Morikawa moral support. Zhu, herself, is also a talented golfer. According to Pepperdine University's website, Zhu played on the golf team from 2014 through 2018. During her time on the team, Zhu boasted an average score of 76.54 and racked up various awards. "Golf is such a big part of my life," share Zhu with The Sun. "It's taught me to be strong when things aren't going well. It's taught me to respect others around me." She added, "Most importantly, golf has created opportunities that have made lifelong memories that I'll cherish forever. I'm so grateful for this amazing game."
According to the New York Post, Zhu once aspired to compete in the LPGA but has since found solace in supporting Morikawa. However, her personal golf knowledge makes her position a bit complicated. "I do get nervous because I play golf, so I know when something is about to get tricky. I know his strong suits and weaknesses. Sometimes his parents will ask me, 'Is that a hard shot'?," she said to the Post. However, Zhu and Morikawa know how to keep things fun and carefree. During a video they shot for the PGA, which Zhu reposted to her Instagram, the couple laughs as they joke about being competitive. "We're never letting each other win," said Morikawa, adding, "I think she beats me probably on 70 % of our chipping competitions."
