Carlton coach Brett Ratten rated his AFL side's performance at five out of 10 after it overcame a slow start to beat bottom side Greater Western Sydney by 67 points yesterday.

The Blues, who had rested skipper Chris Judd, were only 10 points ahead at half-time at Etihad Stadium.

But Carlton kicked nine goals to the Giants' one in the second half to win 15.20 (110) to 6.7 (43) and claim its fifth victory in the first six rounds.

Onballers Marc Murphy and Mitch Robinson were among Carlton's better players, as was ruckman Shaun Hampson with three goals and 15 disposals. Bret Thornton booted three goals for the Blues.

Ratten said the Blues would regain Chris Judd, Jarrad Waite, Ed Curnow and Chris Yarran for their round-seven clash with St Kilda at Etihad Stadium on Monday, May 14.

But the Carlton coach would have preferred to see more fringe players put their hands up to cement their places in the side.

''That's probably [causing] a little bit of frustration for me in saying, 'You had an opportunity and now you might have to move out because of players coming back','' Ratten said.

The Blues lost the clearances tally 41-28 despite winning the hit outs 47-24 through Hampson (31) and Matthew Kreuzer (14).

James McDonald and Callan Ward had seven clearances each for the Giants while Murphy with nine was the only Blue with more than four.

Ratten also accused his players of being too cute with their ball use.

''Their work around the stoppages was a lot better than ours,'' he said.

''They should have been really ready for it considering James McDonald is a clearance player. Our players knew exactly what they were coming up against so there wasn't a complacency issue there.

''We gave the ball back in areas of the ground which we're not really happy about.''

Former Blue Setanta O'hAilpin, in his first game for the Giants, booted two goals in the first half but limped off with a knee injury in the third term. Ruckman Dean Brogan was subbed off earlier in the third quarter with an arm injury.

Giants coach Kevin Sheedy said early indications suggested O'hAilpin had suffered a season-ending anterior cruciate ligament injury, while Brogan would have scans for a possible broken arm.

Sheedy said Adam Kennedy had given a marvellous performance to keep Carlton's star small forward Eddie Betts goalless in his 150th game.

Eighteen-year-old Toby Greene and 35-year-old McDonald were also strong contributors for the Giants.

''It's probably as well as we've played against a very good side,'' Sheedy said. AAP
