West Coast has finished on the wrong end of a thriller against Richmond, going down by 11 points at Optus Stadium as the Tigers snapped their 12-game losing streak. 

In a game that featured 14 lead changes, the Eagles were clinging to a two-point advantage with five minutes remaining in front of 46,350 fans when Harley Reid gave away a high-tackle free kick.

Both Reid and Elliot Yeo ran off to guard their defensive 50m, with the umpire pinging Yeo with a 50m penalty for not standing the mark.

Steely Green nailed the set shot from 30m, and Tyler Sonsie kicked a goal a short time later to put the Tigers in the box seat.

West Coast's No.1 draft pick Willem Duursma made things interesting with a stunning left-foot goal on the run with 88 seconds remaining, but Seth Campbell sealed the 15.9 (99) to 13.10 (88) win for Richmond with a clutch long-range set shot in the final minute. 

Although the Tigers (1-7) remain on the bottom of the ladder, they secured their first win since beating the Eagles in round 19 last year.

West Coast slipped to 2-6, but it was a big improvement on last week's 101-point loss to St Kilda.

The Eagles 65 inside 50s to 45 and had more clearances, but lost the aerial battle at both ends with Noah Balta causing headaches in attack.

West Coast used the week to celebrate the 20-year anniversary of their 2006 flag, with members of that team forming a guard of honour as the Eagles ran through the banner.

There were nine lead changes and plenty of blunders in the first half, with the biggest gaffe belonging to Richmond second-gamer Sam Cumming when he pumped the ball 50m the wrong way.

West Coast kicked the opening three goals of the second quarter - including a two-bounce special on the run from Reid - to open up a 12-point buffer.

But some strong marking in attack from Faull and two goals in the final minute of the half to Balta ensured the Tigers went into the long break with a 10-point lead.

West Coast entered the half-time break having lost a whopping 19 consecutive quarters - a record low for the club.

Alarm bells were ringing for the Eagles when the lead extended to 21 points at the 12-minute mark of the third quarter, but they stormed back into the contest and were just five minutes away from victory before conceding three of the final four goals of the match.

Jack Ross was huge for Richmond with 29 disposals and 11 clearances, while Kane McAuliffe (28 disposals) was also influential.

Noah Balta, Jonty Faull and Campbell kicked three goals each for the Tigers.

Tim Kelly led the Eagles with 30 disposals, seven clearances and a goal, while Harley Reid had a hot first half on the way to 26 possessions, 10 clearances and two goals. 

Elliot Yeo did everything his power to inspire the Eagles to victory, including a rousing left-foot snap in the first 30 seconds of the final term to put West Coast in front, and finished with 20 disposals, 11 tackles and seven clearances. 

Jake Waterman finished with three goals but missed a critical shot in the final term to extend West Coast's lead, and the Tigers roared to victory.

The Eagles travel to Marvel Stadium to face the Demons in round nine next Sunday.
