ST KILDA has locked down two of its brightest players, with defender Jimmy Webster and forward Tim Membrey signing contract extensions.

The close mates had deals set to expire at the end of next season, but Webster signed a three-year deal to see him committed until the end of 2022.

Membrey signed on for another two years and is locked to the Saints until the end of 2021.

Drafted at No.42 in 2011, Webster was due to be a restricted free agent at the end of 2019 but chose not to explore that option.

"I've got a really good manager, Peter Lenton, who figured it all out for me and he was happy with the deal, and so was I, so I didn't really think about it too much," Webster told reporters at RSEA Park on Wednesday.

He sees St Kilda turning around its fortunes quickly.

"The club's been great for me. I've just recently moved around the corner, which helps as well," Webster said.

"It's a great bunch of blokes. Last year we had a pretty good year.

"This year hasn't been great, but I feel like footy's a pretty funny game and can turn around pretty quick, so hopefully next year we can play some good footy."

Webster, 25, was on track to feature very prominently in the best and fairest but has missed five games because of issues with his right groin and a hip flexor.

A more relaxed approach has seen him improve.

"The last couple of years, I was reading what people were writing about me and looking into all that sort of stuff," Webster said.

"I'd have a routine, I'd make sure I was in bed at a certain time and eat the same thing before a game, so I sort of just threw all that out the window. I don't really go and see what people are writing about me or anything like that anymore."

The left-footer is an elite kick, impressive in one-on-one contests and courageous.

Drafted at No.42 in 2011, Webster was due to be a free agent at the end of 2019. 

Meanwhile, Membrey has turned around his goalkicking woes from earlier this season to be one of the side's most important players, particularly in the absence of injured fellow talls Josh Bruce and Paddy McCartin.

The 24-year-old has booted 112 goals in 54 matches since the start of 2016.

He was drafted by Sydney in 2012 at No.46 and joined the Saints two years later as a delisted free agent.

"They gave me a second chance down here at the Saints and I guess I felt like I just really needed to give back," Membrey said.

"(St Kilda coach Alan Richardson has) been really good for me. We've had a lot of honest conversations and I just really feel like I want to repay the club and hopefully we can do that in the years to come."

Membrey's importance has been amplified considering the youth around him in attack, with Rowan Marshall (10 matches) and Josh Battle (seven) having taken on important roles at times in an inexperienced forward line.

"I'm 24 now and not necessarily a younger player, so I guess it's just about accepting that role and knowing that I'm a leader down there in the forward line, with the younger crew around me. so it's just more about staying positive and staying engaged with them," Membrey said.
