English paceman Harry Gurney earned man of the match honours despite putting down two regulation catches, which he admits will result in him copping extra high-ball training this week.

In all the Renegades dropped three catches with Mackenzie Harvey also putting down a straight-forward chance to get rid of Jay Lenton.

But somehow the Thunder failed to make the Renegades pay for their sloppy efforts in the field.

Gurney's night started running downhill when he put down a towering shot by Daniel Sams, who was facing his first delivery.

This is despite the ball hanging in the air for six seconds and there being three fielders who were within range to take the catch.

Thankfully for Gurney, the Thunder allrounder was dismissed soon after for two.

"It was up there for so long and someone shouted 'keeper's', which put me off a little bit," Gurney said.

"It was my catch. I should have taken it. I'm sure I'll have some fielding practise in the morning."

Likewise, he dropped Sangha on 49 in the 20th over - however the game was decided at that point.

Despite the Renegades not firing on all cylinders, they moved into second spot - four points above the fifth-placed Adelaide Strikers - and will be hard to dislodge from the top four from here.

Gurney, who finished with bowling figures of 2-27 including the important wicket of Shane Watson, played down the likelihood of poor finishing costing them their season.

"You want to field well in this format because it can swing fixtures, particularly catches," Gurney said.

"Fortunately neither of those two catches cost us.

"You've got to take your catches and get rid of good players as much as possible. I wouldn't necessarily say that it will decide the competition."
