The 2001-born under-72 kilogram division competitor put together some gutsy showings in the process, none moreso than in the squat.
Maruska missed her first two attempts at 157.5 kg but went all out in her final lift, clearing 165 kilograms to sit in fourth place after the opening event.
That would turn out to be her last miss of the meet, as Maruska cleared 95 kg, 100 kg and 105 kg in the bench press and followed with lifts of 157.5 kg, 165 kg and 175 kg in the deadlift to finish with a 445.0 kg total.
Daria Rusanenko of Ukraine took first place in the 72 kilogram class, setting a world junior record in the squat with a lift of 240 kg before clearing 125 kg in the bench and 177.5 kg in the deadlift for a 542.5 total.
Maruska was coming off a stellar showing at the Canadian Powerlifting Union championships in March, where she set national records in the bench press and deadlift to go along with a new Canadian mark in her overall total.
Interestingly enough, Maruska would broken all three marks again with her showing at worlds.
Canada finished third as a team in the sub-junior division and 12th in the junior class.
