CHAMPION West Coast ruckman Dean Cox is on report in another dark night for the Eagles and a horrible home ground mauling from Geelong at Patersons Stadium. Cox, 32, was booked for an alleged off-the-ball striking incident with Cats midfield sensation and captain Joel Selwood. The six-times All-Australian, who announced on Friday he would play on next season with a new one-year contract, will have his hit investigated and assessed by the league's official match review panel on Monday. Cox is in danger of missing West Coast's Friday night clash with Collingwood at the MCG and the end-of-season home clash with Adelaide in a fortnight. It is only the second time in the big star's 271-game career that Cox has been booked. AFL - West Coast Eagles v Geelong Cats, Patersons Stadium, Perth. PICTURED- Eagle Matt Priddis pushes Geelong's Steve Johnson out of the way. Selwood turned in another outstanding display as the fearless follower racked up 29 possessions and rounded out his blitz with four goals as he continued a highly likely late season collection of Brownlow Medal votes that could run down Gold Coast hot favourite for the award Gary Ablett. West Coast was blown apart inside the first half when the Cats slammed on another unanswered five goals approaching half-time and led by a whopping 56-points at the long break and ran away to a comfortable win 16.11 (107) to just 6.5 (41). PICTURED- Geelong's Joel Selwood pushes brother Scott Selwood into the turf. The Cats round out their qualifying appointments with successive games at their home ground fortress in Geelong against reigning premiers Sydney next Saturday and then Brisbane in Round 23. The powerhouse Cats have won 47 of their last 49 games at home. PICTURED- Geelong's Travis Varcoe tries to gather the ball. The Cats had winners all over the ground and while Selwood and his on-ball team dominated relentless defenders Harry Taylor and Tom Lonergan held West Coast power forwards Josh Kennedy and Jack Darling goalless. Kennedy retained a share of the lead in the Coleman Medal with Hawthorn gun Jarryd Roughead and exciting newcomer Jeremy Cameron from Greater Western Sydney with 60 majors, ahead of Collingwood big man Travis Cloke on 58. PICTURED- Eagle Josh Kennedy. Kennedy and Darling managed only eight possessions each and four marks between them to the final change when the ruthless Cats led by 70 points. Darling booted his only goal inside the last two minutes of the dismal night. West Coast drove a dagger into the heart of arch rival Fremantle's top-two chances for next month's finals with the insipid loss. The Cats all-but sealed a second-place finish for the opening week of premiership play-off series and closed the door on Fremantle climbing into the top-two as the Eagles already remote finals hopes are now dashed altogether. PICTURED- Geelong's James Kelly is congratulated by team mate James Podsiadly after another second quarter goal. Selwood ignited a possessions frenzy around the ball as the Cats burst to a five-goal lead inside the opening 13 minutes and were never threatened again. Geelong's first 14 goals were all booted from running and field snaps in damp and slippery conditions generated from a complete dominance around congestion. Selwood, 25, has now had four best-on-ground outings that could attract top Brownlow votes inside his last seven games. Geelong playing great and 2011 premiership captain Cameron Ling revealed in his television commentary that a fast start had been strategic for the Cats to stifle the Eagles on their home turf. West Coast has been an easy kill in Perth this season with seven losses in 11 engagements at home. The slick Cats wasted no time asserting control with a wide open forward line and two quick goals on the run from dangerous pair Steven Motlop and Mathew Stokes inside four minutes. Motlop turned in a stunning start with six possessions and a second goal in the opening 10 minutes and then athletic big men Nathan Vardy and Josh Walker ran into open goals for a fourth and fifth and an alarming 31-point lead and the home side defence ripped to shreds. PICTURED- Eagle Patrick McGinnity tries to stop Geelong's Steven Motlop from getting away. Motlop, 22, outgunned three separate Eagles opponents in his opening blitz and was withdrawn at half-time with hamstring tightness and the premiership points and Cats 16th win of the season sealed. His fourth minder for the term was renowned defender Patrick McGinnity as West Coast instigated a tighter one-on-one all over the field in a bid to slow the Cats free-wheeling from midfield into the vital scoring zones. An anticipated match-up made from the classics was tough Eagles tagger Scott Selwood with the assignment to try and curb the potential dominance from his older brother and hard-core Cats captain Joel. It wasn't a full-on brotherly reunion as West Coast rotated some of their most experienced on-ballers through minding duties on the influential Cats skipper and play-maker. Selwood, as so often he does and especially with another remarkably consistent season, led an onslaught around the ball along with big possession winning regulars Corey Enright, Andrew Mackie and Jimmy Bartel as well as veteran James Kelly streaming from backward of centre with precise delivery into the dashing small forward battery of Stokes and Motlop who were constant dangers around goal.
