CARLTON coach Brett Ratten believes the remaining seven rounds could produce some unexpected results, and hopes they can aid his side's quest to play finals.

With the Blues a game and percentage out of the top eight, and with matches against the Sydney Swans, Bulldogs and Adelaide in the next three weeks, Ratten suggests the football Gods can play a part in shaping the final eight.

"I think there’ll be some funny results over the next seven weeks between teams," he said.

"Teams that aren’t expected to win will win. You’re never out of it until it’s over."

Despite a gallant last-quarter fight-back that at one point cut a 33-point deficit to seven, Ratten highlighted an undisciplined act by full-forward Brendan Fevola early in the second term as a critical turning point.

A free kick and subsequent 50-metre penalty against Fevola sparked a three-goal run for the Saints, who took the lead and were never headed from that point.

"That was probably the start of it, wasn’t it?" Ratten said of the Fevola incident.

"We were taking the ball up, [and] had a bit of control in that first two or three minutes of the second quarter. Then the free kick, then the 50 (metre penalty), then a kick down, a mark and a goal and then I think they scored another goal within about two minutes."

While ruing poor discipline, decision making and a sub-standard skill level, Ratten said the side had to learn to make more of the chances it's given.

"You get your run at the game and, if you don’t hurt the opposition, then you pay a price," he said.

"I thought clearances, we were well on top first quarter, tackles were about the same, and we had more of the footy. But we missed some really easy shots and to St Kilda’s credit they really got on top of us."

He said the short-term future of No. 1 draft pick Matthew Kreuzer would be assessed this week.

Kreuzer had only six possessions and struggled all night against St Kilda’s Steven King.

"It’s a tough one and I suppose it depends on how the players playing under him are going to come up," he said.

"I thought his first half was down but I thought his last quarter was very good."
