Ko stumbles

Lydia Ko’s struggles have continued after firing a two-over par opening round 73 at the Marathon Classic in Ohio yesterday. Ko, the defending champion, is seeking to win on the LPGA Tour for the first time in a year. After holding the women’s No 1 ranking for 85 weeks, the Kiwi has dropped to fourth and is desperate to regain her consistency. Ko blotted her scorecard with three bogeys in her opening round to find herself 10 shots back from leader Gerina Piller who fired an eight-under 63.
