West Coast Eagles slump to third straight defeat at Patersons Stadium A disappointed Josh Kennedy with team mate Shannon Hurn after the loss to Carlton. WEST Coast's Subiaco fortress is crumbling after a disciplined Carlton inflicted the Eagles' third straight loss at Patersons Stadium last night. The Eagles, rated among the premiership favourites before the season, have slumped to 1-3 after four rounds and face resurgent Port Adelaide at AAMI Stadium next Saturday night as their top-four hopes go on the line. Coach John Worsfold was more concerned with his team's overall form than its home record after the Eagles kicked a horror 7.23 to lose to the Blues by 24 points. "We've won one game, so discount where they are because if you want to play in good finals and be a top team then you've got to win everywhere," Worsfold said. We had 30 scoring shots. Thirty times the ball got close enough to our goal out of 50 times in (51 inside 50 entries). That's right on the money. Kick 20.10 and you're looking like a really sharp team. We just made to many errors tonight. Our ball use and capitalising on the opportunities we created just wasn't quite good enough tonight. Match report: West Coast v Carlton A shoulder injury to captain Darren Glass compounded the loss to, but Worsfold was confident Glass would be available to take on the unbeaten Power. Glass manfully played out the game despite being in obvious discomfort. Carlton coach Mick Malthouse added another win to his good record coaching against his old club the West Coast Eagles. "We knew Glassy was only at probably 50 or 60 per cent of what he could normally contribute, but we were comfortable to do that and try (Bradd) Dalziell in for (Jamie) Cripps," Worsfold said. It was some sort of muscle strain in his shoulder, it didn't pop out. He got through the game and we're confident that he won't pull up any worse than he is tonight so therefore be available next week. So it's now just wait and see. LIVE HQ: Supercoach scores an stats Vice-captain Beau Waters is likely to return for the Port Adelaide match after missing two games with a calf injury, while midfielder Matt Rosa will be considered after making his comeback for East Perth in the WAFL yesterday. It was Carlton's first victory under Mick Malthouse and revived the Blues' season ahead of a clash with Adelaide at the MCG on Saturday. The win took Malthouse's head-to-head coaching record over Worsfold to 11-4. Worsfold launched a spirited defence of premiership veteran Adam Selwood, 29 next month, who was shown up for pace by lightning quick Carlton forward Chris Yarran. Yarran starred with four goals in a best on ground performance, kicking three running goals during the second quarter. Worsfold said he did not feel for Selwood. Eagles skipper Darren Glass grabs his shoulder after hitting the turf trying to gather the ball. You play footy and you match up on guys with different strengths. I feel for a lot of forwards that Adam plays on who haven't had a kick on him in the past," he said. Give it your best shot and that's what he did. So I respect him for that. It's hard to stop if they get goal side of you and they got us off probably just a couple of poor turnovers when we had control of the footy. So our boys were setting up to attack and we messed it up, a couple of silly errors that cost our teammates.
