Peel Thunder have suffered another finals setback after a narrow eight-point defeat to the Perth Demons at Lathlain Park on Saturday.

Peel held the lead until the final quarter, where Perth kicked four quick goals to steal the win 10.15 (75) to Thunder’s 10.7 (67).

Fremantle defender Taylin Duman said the Thunder came out defensively in the final quarter, which costed them the game.

“We went out there and tried to protect the lead that we had, we didn’t go out there and try to pile on a few more goals,” he said.

A strong start by the Thunder in the first term put them ahead, with goals Mitchell Crowden and Gerald Ugle, and two from Brady Grey who returned from injury this week.

Duman said the Thunder had focused on a hot start.

“Winning the first quarter was one of our key indicators, and we ticked that off,” he said.

“Grey kicked a couple early and really helped us win that first quarter”.

Peel maintained their lead during the second and third terms, with strong performances from Brady Grey, Danyle Pearce, Harley Bennell and Michael Johnson.

Duman said Johnson’s experience and leadership in defence was a key to Peel’s success in the first three terms.

“He was really strong throughout his communication, helping to set up all the young blokes down in defence,” he said.

Perth came out with intensity leading into the final quarter, scoring four unanswered goals to put them ahead of the Thunder.

Peel fought back, with Lloyd Meek scoring and inside 50 in the last few minutes, but it wasn’t enough against the Demons' pressure.

With five games remaining until finals, Duman was confident in their ability to secure a spot in the top five.

“We were in a similar position last year. Hopefully we can string a few back, as we get a few boys back from injury,” he said.

Peel Thunder face South Fremantle at Rushton Park on Saturday 21 July at 2:15pm.
