Rene Paredes kicked five field goals while the Stampeder defense shut down a potent Saskatchewan offense as they clinched a playoff spot with a hard-fought 15-9 win.
Saskatchewan is now 6-6 on the season.
Calgary returns home next week to host the struggling Montreal Alouettes, while Saskatchewan travels to Ottawa.
The Stampeders opened the scoring at 8:45 of the first quarter on a 38-yard field goal by Paredes that capped a 56-yard, 10-play drive.
Paredes extended the Stamps lead to 15-2 midway through the fourth quarter via a 30-yard field goal.
The Stampeders also forced the Riders into a turnover on downs and Jamar Wall had an interception.
The Riders lost star receiver Naaman Roosevelt early in the second quarter on a devastating hit by Calgary’s Tunde Adeleke; Roosevelt was eventually helped off under his own power, with Adeleke drawing a flag on the play. TSN reported that Roosevelt, who had two receptions for 23 yards, was undergoing concussion protocol.
The similarity between the two games was the line play.
This one led to Chris Jones trying to save his quarterback by putting in Brandon Bridge to feel the pounding Kevin Glenn was feeling for the majority of the afternoon. Glenn completed 12 of 19 passes for 127 yards and an interception before being removed from the game. Bridge found Bakari Grant, Holley and Rob Bagg – the latter for a spectacular one-handed grab – before tossing a picture-perfect touchdown pass to Devon Bailey. But a sack by Stampeders’ Ja’Gared Davis forced a fumble, which Davis then recovered at the 52-yard line with 10 seconds remaining.
That much was clear on Sunday in a 15-9 loss.
