Calgary goaltender Curtis Palidwor rebounded from a shaky start in Toronto earlier in the week, stopping 49 of 57 shots to defeat the New York Saints 12-8 in front of 11,596 hometown fans on Sunday afternoon.
Palidwor allowed two goals in each period, going nearly 16 minutes without allowing a Saints goal in the second half.
Roughnecks defenseman Tyson Leies scored four goals to earn Player of the Game honors. Each of his first three goals gave his team a one-goal lead, while his fourth goal was the final marker scored by the Roughnecks.
"This was an important win for us, given the way we played against Toronto," Leies said. "We came back with a strong game today, and with the same effort, we hope we can deliver a home playoff game for the fans."
Kaleb Toth also scored five points, tallying four assists and a goal, while Kyle Goundrey added two goals and two assists for the Roughnecks. Bryan Bendig led the Saints with five points, recording two goals and three assists.
The Roughnecks will be idle for nearly three weeks, until they go on the road to face Philadelphia and New York for a pair of back-to-back contests. The team will then return to Calgary for an important interdivision game against the Ottawa Rebel on March 30.
