The 2022 Australian Open is underway in Melbourne at the Victoria Golf Club and Kingston Health Golf Club. The men's and women's championships are taking place concurrently for the first time, with both categories competing for equal prize money. David Micheluzzi battled past a strong field to finish Day 1 at the top of the leaderboard with a three-point lead. The 26-year-old carded a 7 under 63 in the opening round of the tournament, his lowest-ever DP World Tour round. He was followed by Josh Geary and Matthew Griffin, who finished four under 66. Meanwhile, world No. 3, Cameron Smith, who is the highest-ranked player on the field, struggled on the first day, scoring a one-over-par 71, which leaves him with plenty of play on Friday to move into the weekend. In the women's event, 21-year-old, Grace Kim topped the leaderboard, carding the lowest score at the Kingston Health Golf Club. The rookie finished at seven under 66 to finish two strokes ahead of compatriots Hannah Green and Jiyai Shin.Australian Open@AusOpenGolfLow scoring, high energy during round one of #AusOpenGolf Leaderboard: golf.org.au/ausopen/leader…146Low scoring, high energy during round one of #AusOpenGolf ⛳️Leaderboard: golf.org.au/ausopen/leader… https://t.co/JuxvSaoVj4The Australian Open will continue until Sunday, December 4.
