After juniors, the Mouat rink found immediate success on the World Curling Tour, winning the Stu Sells Oakville Tankard and Oakville OCT Fall Classic tour events to begin the season. The Team would win the 2017 Boost National, becoming the first Scottish team to win a Grand Slam title. Also on the tour that season, the team would win the Dumfries Challenger Series and the Aberdeen International Curling Championship. The team had less success at the second slam they played in that season the, 2018 Meridian Canadian Open, failing to make it to the playoffs. Later in the season, the team won the Scottish Men's Curling Championship, and defeated the British Olympic team (skipped by Kyle Smith) in a playoff to earn the right to represent Scotland at the 2018 World Men's Curling Championship.
