The Stampeders beat the Tiger-Cats 30-24 on a penalty filled night in Calgary Sunday night.
Hamilton committed 14 infractions for 125 yards compared to Calgary’s fine penalties for 22 yards as the Stamps improved to a CFL best 7-1-1.
The Stamps forced the first turnover of the contest by blocking a Brett Maher punt early in the first quarter and converted it into a Rene Peredes field goal.
The Tiger-Cats engineered a 13 play drive that resulted in a 21 yard touchdown throw by Zach Collaros to Terrence Toliver.
But Calgary answered right back when Bo Levi Mitchell threw a long bomb to DaVaris Daniels who ran it into the endzone for a 76 yard touchdown and a 10-7 lead on the Cats at the end of the first quarter.
Peredes added two more field goals, from 17 and 41 yards, to stretch the Stampeders’ lead to 16-7 just before halftime.
Maher connected on a 47 yard field goal 3:45 into the second half that cut Calgary’s lead to 16-10.
But on the first play of the fourth quarter Stamps running back Jerome Messam ran for a three yard major to give Calgary a 24-10 lead.
Peredes then added his fourth field goal of the game, his 27th consecutive conversion, to make it 27-10.
Collaros and Toliver hooked up on a 26 yard touchown with just under five minutes to play, but Hamilton failed on a two point convert attempt, making in 27-16.
After Tommie Campbell’s 115 yard interception return for a touchdown was called back on an illegal contact penalty vs. Calgary, Collaros found Tasker for a five yard score, cutting the Stamps lead to 27-24.
But Peredes hit a 45 yard field goal with 37 seconds left to play to seal the victory.
Calgary entered the game on a seven game unbeaten streak while Hamilton has now lost nine games in a row against the Stamps.
