The Saskatchewan Roughriders improved their CFL-best record to 11-4 by defeating the host Ottawa REDBLACKS 20-13 on Friday.

Saskatchewan will clinch a home playoff game if the B.C. Lions (8-7) lose to the visiting Calgary Stampeders (8-6) on Saturday.

However, a Lions victory would move the Roughriders one step closer to securing first place in the West Division.

Friday’s loss eliminated Ottawa (4-11) from playoff contention.

The Roughriders enjoyed a robust start on offence, marching 84 yards in 12 plays for their first touchdown — a one-yard run by A.J. Ouellette. The drive consumed 5:23.

Saskatchewan reached the end zone early in the second quarter when Antoine Brooks Jr. scored on an 85-yard interception return. Trevor Harris then found Ajou Ajou for a two-point convert to increase Saskatchewan’s lead to 14-0.

Ottawa did not hit the scoreboard until Lewis Ward kicked a 25-yard field goal on the final play of the first half.

After a scoreless third quarter, the Roughriders struck for a 66-yard touchdown pass from Trevor Harris to Dohnte Meyers, who scored 19 seconds into the fourth frame to put Saskatchewan ahead 20-3.

Ottawa responded with an 11-play, 80-yard march that concluded with a nine-yard TD pass from Dustin Crum to Justin Hardy. Lewis Ward added the convert to make it 20-10, Roughriders.

Saskatchewan was poised to fatten the lead after it marched 66 yards in nine plays, reaching the REDBLACKS’ five-yard line. However, Harris was hit as he was throwing and Bryce Carter caught the dislodged football. Carter returned the pick 81 yards before being tracked down from behind by Ouellette on Saskatchewan’s 16-yard line.

Crum was sacked by Mike Rose on the next play. Shortly thereafter, Ward kicked a 25-yard field goal to make it 20-13.

The Roughriders responded with back-to-back passing first downs, courtesy of receptions by KeeSean Johnson (13) and Meyers (25), before Ouellette ran for a first down to seal the game.

The Roughriders are to return to action next Friday against the Toronto Argonauts (7 p.m., Mosaic Stadium) in the “Lights Out” game.
