A ferocious West Coast fell short to St Kilda in a tense eight-point loss on Sunday at Optus Stadium in an entertaining clash that threatened to produce the upset of the season. 

With a foothold in the top eight on the line for the Saints, and the Eagles playing for respect, the match became a thrilling high-stakes battle with a difference.

St Kilda was forced to come from 31 points down in the second quarter to secure the important win, eventually prevailing 12.13 (85) to 12.5 (77) after a nail-biting final term.

They might not have expected the spirited Eagles team they encountered after last week's 171-point loss to Sydney, and were made to earn the important win from start to finish. 

Indeed, West Coast entered this match having not won any quarter since the third term against Gold Coast in round nine, losing 21 on the trot as their season lurched from low to new low.

That streak ended on Sunday, however, as the home team responded to last week's humiliation with one of their best and most ferocious quarters of football this season.

Captain Luke Shuey set the tone with eight tackles and his teammates followed, applying relentless pressure to the visitors and riding a wave of momentum to make their intentions for the day clear.

Small forward Noah Long provided the early highlight when he used one hand to guide a brilliant checkside goal through from the boundary, with the Eagles celebrating every effort with enthusiasm.

When Jamie Cripps slotted his set shot in his first game since round three, the Eagles had a seven-point quarter-time lead and reason to believe in an unthinkable upset.

Belief turned to expectation in the second quarter as West Coast showed no sign of relenting, kicking four consecutive goals to open a match-high 31-point lead.

The defensive efforts of Tom Barrass were outstanding, while the Eagles settled into a deliberately controlled game style and took 43 marks to 13 as the Saints flooded numbers back.

Two late goals from young St Kilda forward Anthony Caminiti proved crucial in controlling the margin before half-time, and the visitors were able to make their move in the third term.

They matched the Eagles' pressure through the hard-tackling Crouch, took more risks with the ball, and started forcing turnovers in the front half rather than folding back.

The Eagles responded with an impressive patch of their own, with impressive draftee Elijah Hewett hitting a contest at pace and snapping a terrific goal that restored the margin to 21 points.

General play was on the Saints' terms, however, and they capitalised with late goals that set up a thrilling final term, with the Eagles clinging to a one-point lead at the final change.

Missed chances in the final quarter will be rued by both teams, with Owens' goalsquare goal in the opening minute the only major of the term.

Cripps had a set shot in the final minute that could have set up a grandstand final centre bounce, but he sent his shot wide as the Saints escaped with the critical points.
