Her sisters have excelled as Marauders for the past three years, but on Sunday, Tia Svoboda announced her presence at McMaster.
The rookie had a pair of tries in her team's eight-try performance, as Mac easily cruised past York 50-26 under the lights at Ron Joyce Stadium.
Tia's sister Sara added a try of her own to go along with five converts, while Taylor Price, Monique Sluys, Britni French, Maddy Seatle and Brii English also crossed the try line in the victory.
Tobi Olvotomo answered with a pair of tries for the Lions in a losing effort, with teammates Petra Woods and Tia Anderson-Hudson also touching down. Catherine Belanger converted on three of four attempts.
The first try of the night came in the seventh minute, as French slashed through the York defensive line to touch down near the posts. Six minutes later, Price repeated the feat, with Sara Svoboda notching her first convert to push the Marauders ahead 12-0.
Tia Svoboda's landmark first try as a Marauder followed in the 21st minute, as she launched a long solo run down the left wing and curled in to touch down under the posts. Her sister duly made good on the resulting convert.
Another pair of tries, from Seatle and Sluys, powered McMaster ahead by a commanding 33-0 margin, and a stout defensive stand on the eve of the halftime break ensured that they retained it into the interval.
Just four minutes from the restart, English jump-started the scoring again with a try of her own, and the youngest Svoboda would follow just four minutes later, as Mac's lead swelled to 45-0.
Sister Sara crossed the line for her lone try of the night to complete the Marauders scoring and bring the margin to 50 points, before the Lions began chipping away at their deficit.
Anderson-Hudson got her team on the board in the 60th minute, with Olvotomo following with a pair of tries and Woods capping the night with one of her own on the stroke of the final whistle, as York salvaged some offensive spark in a losing effort.
NEXT UP: The Marauders enjoy a week away from competition, before travelling to London on Friday, September 15 for a clash with the Western Mustangs.
