A pair of Calgary streaks came to an end Saturday at McMahon Stadium as the Stampeders dropped a 33-27 decision to the Toronto Argonauts.

The loss snapped the Stamps’ four-game winning streak as well as their 10-game winning streak at home. Their previous loss at McMahon — which came on Aug. 18, 2012 — was also to the Argos.

This latest setback saw the Stamps build a 25-15 lead by the 2:19 mark of the third quarter, only to see the Argos take control of the contest and outscore Calgary 18-2 the rest of the way.

The Stamps fall to 9-3 while the Argos are 8-4.

“Inconsistent,” said Stampeders head coach and general John Hufnagel of his team’s performance. “We were playing a good football team. We did some good things. Defensively, we got a couple of turnovers in the first half and, offensively, we capitalized on them.

“In the second half, we didn’t play very well. Offensively, we had too many penalties. We were completing passes but we were moving backwards because of penalties. Defensively, we didn’t tackle very well in the second half.”

The Stamps committed six penalties in the second half, none more critical than an offensive pass interference call against Jabari Arthur that wiped out a 67-yard touchdown pass to Brad Sinopoli.

“It was called,” shrugged Hufnagel when asked about the infraction. “We move on. That didn’t cost us this football game.”

After Toronto opened the scoring on a four-yard touchdown pass from Zach Collaros to John Chiles — just two plays after a Patrick Watkins interception — the Stamps rallied with 11 straight points to take an 11-7 lead after one period.

The Calgary points came courtesy of a 52-yard Rene Paredes field goal, an 11-yard touchdown pass from Kevin Glenn to Arthur and a Rob Maver punt single.

After Toronto got a punt single of its own from Swayze Waters, the clubs traded touchdowns to make the score 15-12 at halftime.

First, Stamps quarterback Drew Tate scored on a third-and-goal gamble from the Toronto one-yard line.

The Argos replied with a two-yard touchdown shuffle pass from Collaros to Andre Durie.

The Stamps extended their lead early in the third quarter on Glenn’s 17-yard touchdown pass to Marquay McDaniel.

Toronto quickly answered with a scoring drive that was capped by a 28-yard touchdown catch by Dontrelle Inman.

After tying the game on a 40-yard Waters field goal, the Argos took the lead with a little more than eight minutes to play in regulation as Collaros hooked up with Mike Bradwell on a 34-yard scoring pass.

Singles — two for Calgary and one for Toronto — accounted for the rest of the scoring.

Calgary had a couple of chances in the dying seconds to pull even, but Anthony Parker was ruled to have been out of bounds when he caught a tipped Hail Mary pass in the end-zone. Toronto then recovered a loose ball in the end-zone on the final play of the game when the Stamps completed a pass to Arthur, who punted the ball in an attempt to allow an onside teammate to recover for a touchdown.

Larry Taylor had a great night for the Stamps, racking up 224 return yards.

Glenn, making his first start since the Labour Day Classic, threw for 225 yards and two touchdowns.

“Too many mistakes,” said Glenn. “Turnovers, penalties — took us out of some drives. We can’t consistently do those things. Tonight, it caught up with us. You’ve got to give Toronto credit — they came in and won the game.”

The Stamps are on the road next Saturday when they face the Hamilton Tiger-Cats in Guelph, Ont. Kickoff is at 2 p.m. MDT.
