AFL.com.au's Riley Beveridge looks at the Carlton players who have made the biggest impact in centre clearances this season:

PLAYERS USED: 25 Blues have attended a centre bounce in 2018.

RUCKMEN:
2018 ruck attendances (top two): Matthew Kreuzer (228), Matthew Lobbe (96)
Centre square hit-outs per game (minimum five games): Andrew Phillips (8.6)
Centre square hit-outs to advantage differential (team): -0.5 (10th) 

ONBALLERS:
Most common ruck-rover combination: Matthew Kreuzer-Patrick Cripps (23)
Most used midfielder (midfielder who attends most centre bounces): Patrick Cripps (464)
Centre clearances won (team differential): +0.8 (third)
Centre clearance king (minimum five games): Patrick Cripps (3)

ANALYSIS: It's all about Patrick Cripps. The Blues are the third-best centre clearance team in the competition this season, mainly on the back of Cripps' excellence. He has attended 464 centre bounces this year, clearly the most of anyone at the Blues. The impact of Zac Fisher has been particularly surprising, with the youngster recording a positive clearance differential of 9.6 per cent. It's the best of anyone at Carlton with more than 100 centre-bounce attendances this season. Of the seven Carlton players to attend more than 100 centre bounces this year, four are 21 years of age or younger.
