In April 2018, Haglund claimed her first Ladies European Tour title at the 2018 Lalla Meryem Cup in Rabat, Morocco, following a playoff. Having shared a three-way tie for the 72-hole lead with overnight co-leader Sarah Kemp and the 2017 event champion Klára Spilková on three-under-par 285, Haglund took the spoils after blasting a 249-meter drive down the 18th fairway and converting a four-foot putt for birdie.[5] Following the victory, Haglund rose from 276 to 204 in the Women's World Golf Rankings and topped the 2018 Ladies European Tours Order of Merit, five tournaments into the season.
Haglund won the Symetra Classic and received one of the two sponsor invites for the 2018 Women's PGA Championship, but did not make the cut. She finished 12th on the 2018 Symetra Tour official money list, narrowly (by $2,027) missing out on the full exemption to the LPGA Tour awarded the top ten.[6]
