WINNIPEG -- Ricky Foley has a nickname for the Toronto Argonauts after they pulled off their fifth come-from-behind win this season.

"Cardiac Kids, right?" the veteran defensive end said after his team's 27-20 victory over the Winnipeg Blue Bombers on Friday.

"It's crazy. It's almost like we need to get down a little bit … You can look at it as a negative, or you can sit here and say we're never going to quit, we're never going to die.

"The scary thing is, once we put together a full game, who's going to beat us?"

The 11-year veteran helped out in the win, which improved Toronto's record to 5-2 while the Bombers fell to 3-5.

The Argos were down 17-14 heading into the fourth quarter when Toronto defensive back A.J. Jefferson took Lirim Hajrullahu's punt and ran 70 yards for the touchdown at 3:44 to give them their first lead.

On the following series, Bombers quarterback Robert Marve -- making his first pro start -- completed a pass to Rory Kohlert, but he was hit and fumbled. The ball was recovered by Foley.

Toronto then put together a nine-play, 43-yard drive, including a third-and-one gamble, that ended with Tori Gurley holding onto a five-yard pass from Trevor Harris in the end zone at 10:26.

Argos kicker Ronnie Pfeffer hit the post on his convert attempt and the score stayed at 27-20.

Winnipeg tried to regain the lead, but Marve couldn't pull off any magic and turned the ball over on downs with 24 seconds left.

Toronto's scoring also came off Pfeffer field goals from 31 and 44 yards and a single off a missed 41-yard attempt. He was good on his other convert after a Diante Spencer five-yard TD reception in the first quarter.

Harris completed 18-of-24 pass attempts for 168 yards with no interceptions and two touchdowns.

Marve, who was replacing Drew Willy (knee) and had got the start ahead of usual backup Brian Brohm, was 18-of-29 for 203 yards with one interception and one TD. He also ran seven times for 37 yards.

His dad, Eugene Marve, a former NFL linebacker, was in the crowd of 27,246 at Investors Group Field celebrating his birthday by watching his son.

"It felt good," Marve said of his start. "I came here for the win, though. We lost. It's kind of a bummer.

"We came out hot, but we gotta be able to keep the momentum. We gotta stop kicking field goals and score more touchdowns."

He said he had a "little stomach virus" and threw up during the game.

"I'm not a big one to get into excuses," he added. "That's kind of the way I was cramping up, but that's part of the game. You gotta play with it. You gotta score more points."

He appeared to hurt a finger on his non-throwing hand, but said it was OK.

Hajrullahu booted four field goals from 25 and 46 yards and a pair from 53 yards. He also missed a convert attempt after running back Cameron Marshall's 56-yard, catch-and-run TD.

"Special teams plays a huge role in giving momentum and taking it back, and we just gave at the wrong time," Hajrullahu said.

Toronto head coach Scott Milanovich said when the game "is at its most desperate, our guys seem to play their best."

"That's something that every team doesn't have," he said. "You keep playing like this, you're going to end up, it's going to bite you in the ass. So we've got to find a way to obviously play a little better earlier in the game."

The Bombers, who are entering a bye week, led 9-7 after the first quarter and 15-13 at the break.

"I feel like it came down to about two or three big plays," said Bombers defensive tackle Bryant Turner.

"I know one of them was the special team return on the punt. That was pretty much the dagger into the whole thing, which we didn't feel that way until the clock hit zero."
