St Kilda scored its third win of the season defeating Port Adelaide by two points in a hectic last minute thriller.

The win puts the Saints 11th on the ladder as they jump up four spots with one more match to remain in the AFLW season.

The Saints' 4.11 (35) held onto the win despite their goal inaccuracy, which almost cost them the game against the Power 5.3 (33).

The Saints trailed at half time by 12 points as they headed into the second half with 22 per cent goal kicking efficiency. The Saints however, kept the Power goalless for the rest of the match.

Georgia Patrikios was the Saints' highest disposal winner, collecting 19 touches. Just behind her was Hannah Stuart with 15 and a goal, captain Hannah Priest and Rosie Dillon too collected 15 joining Stuart.

Following Stuart's goal, Darcy Guttridge, Kate Shierlaw and Lucy Burke also scored for the Saints. Olivia Vesely unfortunately suffered a concussion during the second quarter and took no longer part in the match.

Captain Erin Phillips showed why she is one of the best players in the competition as she led her the Power collecting 21 touches, making a real impact to keep her team within the game.

Hannah Ewings too, continued her brilliant season with 17 touches, a goal, and a whopping eight tackles.

Following Ewings' goal, Jade De Melo, Kate Surman and Lily Johnson hit the scoreboard, as well Gemma Houghton in her 50th game milestone.

Priest spoke post game about the importance of the win to the club and fans after what has been a tough season for the Saints.

"It's been a pretty tough going this season but we've really stuck together as a group and today we just wanted to play with a lot of desperation and Saints heart, and I'm really proud we did that", she said.

Priest spoke about the turning point for the Saints as they trailed at half time with poor goal efficiency to the Power.

"We just went out really hard and wanted to play our best four quarter game and I thought we did that", Priest said.

St Kilda coach Nick Dal Santo expressed his emotion and how he was going in the remaining minutes.

"There's moments where you feel like you've got some control throughout a game and then there's a lot of moments where you feel like it's up to the players to do the best that they can possibly do, he said".

"I mean it's clear we're on a journey, we're a young group that's evolving and growing from week to week and I was really pleased with some individuals today that I thought made some huge steps forward.

"Even in that last five minutes structurally not ideal, contest structures not ideal but they just found a way so I was really pleased and that's without sending any messages out or having a great deal of control.

"It’s been a tough month we've had some close losses, we’ve been blown out in particular games but I was really proud of our group's resolve today and ability just to keep pushing.

"I think we were down by roughly a couple goals at half time and we just stayed the course so I'm really pleased obviously to get the outcome in regards to a win but the way we went about it".

Dal Santo expressed how unbelievable he thought Phillips was for the Power especially in the second half.

"I thought her (Nic Stevens) matchup with Erin Phillips who sitting on the bench thought,'Erin's actually trying to take over the game' she went into the ruck, I thought she was fantastic in the start of the last quarter with her clearance work", Dal Santo said.

"You pay money to see the best players go head to head and I thought it was just a great contest between those two in particular".

Port Adelaide coach Lauren Arnell discussed how frustrating the close loss was for the Power who went goalless in the second half.

"It's disappointing, I think (we had) definite opportunities in that last quarter, we certainly allowed far too much score for the Saints and didn’t create enough for ourselves so the Saints were the better team on the day", she said.

The Saints are looking to finish their season on a high when they take on the Crows in their next match at home. While the Power will host the Bombers also to finish off their first season being in the competition.
