A record toss by Bo Levi Mitchell helped the Stampeders jump out to a 17-0 halftime lead Saturday evening at McMahon Stadium.

Mitchell’s 100th career touchdown toss – which was also Marquay McDaniel’s first trip to the endzone in 2017 – was the first of two major scores for the Stamps in the opening two quarters.

Calgary’s Lemar Durant registered the other TD on a picturesque corner route.

Defensive lineman Charleston Hughes continued to close in on the team’s all-time sack record with three takedowns of ex-Stampeder Kevin Glenn to help limit the opposition to just 62 total yards of offence at the break.

A 23-yard field-goal by Rene Paredes concluded Calgary’s initial offensive series before James Vaughters and Micah Johnson made back-to-back plays in the backfield on behalf of the defence.

While the second-quarter interception of Mitchell by Sam Williams did not lead to any points for the visitors, it did put an abrupt end to a promising possession highlighted by a 44-yard catch down the sideline from McDaniel.

Head coach Dave Dickenson went two-for-two on challenges in the first 2:20 of action with both yellow flags leading to penalties assessed to the Saskatchewan secondary.

Punishing his way through Riders defenders, running back Jerome Messam headed to the locker-room with 96 rushing yards on 17 carries.
