CALGARY -- Zach Collaros threw four touchdown passes including a game-winning 34-yard toss to Mike Bradwell in the fourth quarter to lead the Toronto Argonauts to a 33-26 win over the Calgary Stampeders on Saturday.
Collaros also threw TD passes to John Chiles, Andre Durie and Dontrelle Inman as the Argos (8-4) halted Calgary's four-game winning streak overall and 10-game streak at home.
Swayze Waters added a field goal and a pair of singles for the Argos.
After watching Calgary's previous two games from the sidelines with a knee injury, Kevin Glenn started at quarterback for the Stamps (9-3) and threw a pair of touchdown passes to Jabari Arthur and Marquay McDaniel.
Back-up quarterback Drew Tate also ran for a one-yard TD, Rene Parades kicked a field goal and a single, while Rob Maver booted a single.
With the Stamps trailing by six points late in the fourth quarter, Brad Sinopli caught a pass from Glenn and appeared to run for a 57-yard touchdown, but the play was called back after Arthur was flagged for offensive pass interference.
Early in the first quarter, Toronto linebacker Robert McCune tipped a Glenn pass right into the hands of cornerback Pat Watkins, who ran the ball back to the Calgary three-yard line.
Two plays later, Collaros tossed a four-yard touchdown pass to Chiles to give Toronto an early 7-0 lead.
The Stamps answered right back with a 52-yard field goal by Parades, before linebacker Juwan Simpson sacked Collaros and forced a fumble that Demonte Bolden recovered and ran back five yards to the Toronto 27-yard line.
Four plays later, Glenn threw an 11-yard strike to Arthur in the end zone to give the Stamps a 10-7 lead.
Rob Maver kicked a 59-yard single for Calgary late in the first quarter, before Waters responded right back with an 80-yard single for Toronto early in the second.
Turnovers continued to plague the Argos in the second quarter as Collaros fumbled the ball once again after being sacked by Calgary's Charleston Hughes.
Simpson recovered the ball at the Toronto 28-yard line and the Stamps took advantage of the turnover as Tate ran for a one-yard touchdown to cap off a seven-play drive.
Collaros responded by engineering a six-play, 65-yard drive that he capped off by tossing a two-yard touchdown pass to Durie to pull the Argos within three points.
Toronto had a chance to tie up the score late in the first half, but Waters missed a 43-yard field goal.
Larry Taylor ran the opening kickoff of the second half back 34 yards to give the Stamps great field position at their own 54-yard line. Calgary took advantage as McDaniel caught a 17-yard touchdown pass from Glenn just four plays later to put the Stamps up 25-15.
The Argos responded right back on their next drive as Collaros threw a 28-yard pass to Inman, who was wide open in the end zone. The TD capped off a four-play, 82-yard drive and pulled Toronto within three points once again.
The Stamps had a great chance to extend their lead, but Watkins hauled in his second interception of the game when he picked off a pass by Glenn that was intended for Kenny Stafford.
Waters then kicked a 40-yard field goal late in the third quarter before Collaros led the Argos on a four-play, 70-yard drive that he finished off by throwing the game-winning touchdown to Bradwell.
Notes: Parades had kicked 15 straight field goals until he missed a 34-yarder late in the fourth quarter that went through the end zone for a 47-yard single. a Argos running back Chad Kackert missed the game with a concussion he suffered during Toronto's 31-29 road win in Regina over the Saskatchewan Roughriders last Saturday. Kackert also missed the six games leading up to the win over the Riders with a knee injury. a The Stampeders honoured former owner Sid Gutsche, who passed away last week at the age of 64, with a moment of silence before the game. Players also wore memorial decal on their helmets. a The Stamps and Argos now have all-time records of 42-42-1 against each other. a The Argos were also the last team to beat the Stamps at home when they won 22-14 on Aug. 18, 2012.
