After taking a break from road racing in 2016 with the High5 Dream Team to focus on her Rio Olympics campaign, Baker signed for Orica-Scott to race in the Women's World Tour team for 2017.[9] In her first European race for the team at the end of May, Baker was among the 90 non-finishers of 121 that started at Gooik–Geraardsbergen–Gooik.[10]
Baker withdrew from the 2017 Women's Tour on the opening stage after experiencing a racing heart and sharp pains in her chest and arm.[11] She was diagnosed with supraventricular tachycardia, which is not a life-threatening condition, but needed to be treated to continue as an athlete. She had surgery in early August, and resumed training for a mixed road and track season in the run-up to the 2018 Commonwealth Games.[12] Following the successful surgery, Baker undertook a three-month training block in Australia before racing at the Oceania Track Championships in November 2017.[13]
