Alex Kenyon has signed a new one-year deal with the club.
The former Stockport County midfielder signs for his seventh season with the Shrimps after signing in the summer of 2013 and has since made 216 competitive appearances for the club.
Kenyon said: "I'm just so happy to get it done.
"I've spoken a lot with the gaffer and he told me what I needed to do so I went away and worked hard.
"I've been out working with Luke (Conlan) near enough every day and I feel like I've come back much fitter and stronger.
"We've been doing the half-mile runs this week and I've completed them all in the best times I ever have, I feel good and can't wait to get going."
Boss Jim Bentley added: "We had a long conversation toward the end of last season and I've been in contact with Alex every week over the closed season.
"He's worked extremely hard over the summer and has come back in great physical shape.
"He ticks a lot of boxes, he's good in the dressing room, he's organised, competitive, he wears his heart on his sleeve, he can cover numerous positions while offering left foot balance and good heading ability.
"He's been a good player for us and I'm really pleased to have him on board."
