CALGARY — The Calgary Stampeders secured a playoff spot with a 38-16 win over the visiting Toronto Argonauts on Friday.

Calgary moved to 11-2 atop the CFL's West Division and became the first team this season to nail down a post-season berth.

Dropping to 3-10 in the East Division further damaged Toronto's playoff chances. The Argonauts lost their fifth in a row and fell to 0-6 on the road this season.

Calgary's Marken Michel caught a pair of touchdown passes and Juwan Brescasin contributed a touchdown catch. Backup quarterback Nick Arbuckle scored on a one-yard plunge.

Rene Paredes kicked three field goals for the Stampeders in front of an announced 24,126 at McMahon Stadium.

Toronto quarterback McLeod Bethel-Thompson and backup James Franklin scored short-yardage touchdowns for the Argos. Argos kicker Zack Medeiros made one of two field-goal attempts.

Stampeder quarterback Bo Levi Mitchell improved to 10-0 in career starts against the Argonauts. The Texan completed 20 of 34 passes for 307 yards and a pair of touchdown throws.

Toronto quarterback McLeod Bethel-Thompson dropped to 2-5 as a starter since the Argos lost Ricky Ray to a season-ending neck injury in Week 2.

Bethel-Thompson was 30-for-45 in passing for 272 yards. He scored a one-yard rushing touchdown with two seconds remaining in the game.

Argos safety Jonathan Dowling picked off Mitchell early in the fourth quarter, but Stampeder defensive lineman Derek Dennis stripped him of the ball for teammate Markeith Ambles to recover.

Calgary capitalized on the turnover with Brescasin scoring on Mitchell's three-yard toss.

A receiving corps thinned by injuries before and during the game hampered Calgary's conversion from the red zone for three quarters.

The Stampeder offence relied on chip shots from Paredes to wrest points out of three drives.

But Michel's second touchdown of the night on a 21-yard catch-and-run pushed the Stampeders ahead 31-10 to start the fourth quarter.

A Brandon Smith interception midway through the third gave Calgary the ball on Toronto's 11-yard line. Arbuckle scored on a one-yard plunge.

The Stampeders led 17-10 on a 14-yard Paredes field goal early in the second half.

Calgary was up 14-10 at halftime settling for 13- and 9-yard field goals on first-and-goal opportunities.

Already without star receivers Kamar Jorden (knee), DaVaris Daniels (collarbone) and Eric Rogers (knee), Calgary was further decimated at that position before halftime Friday.

After a high hit late in the first quarter, Reggie Begelton walked off favouring his right arm and did not return.

Brescasin's halftime treatment kept him out of the game until midway through the third quarter.

Medeiros was good from 29 yards in the first half after putting a 47-yard attempt off the upright.

Both teams scored on their opening drives.

Franklin finished a 12-play march for the Argos with a two-yard plunge for a touchdown. The visitors led 7-6 on a Medeiros convert kick.

Michel capped Calgary's opening drive darting 37 yards for a major after the handoff. Paredes was wide left attempting the single-point convert.

Instead of returning to Toronto, the Argonauts remain in Calgary next week to prepare for next Saturday's road game against the B.C. Lions.

Calgary's next game is in Montreal against the Alouettes on Thanksgiving Day.
