The young defender has become an important part of the team and has learnt a lot in the process this season.
Still only a teenager, Tom Hamer, who operates at right-back reflected on the back-to-back wins recently and knows how important his and the defensive unit's responsibility is when it comes to getting positive results.
"It's important obviously, you keep a clean sheet you can't lose a game.
"Callum's two goals and the two goals before in the 2-0's have won us the game, but it's important to remember for defenders to do out bit.
"It's not just the defenders though it's the whole team, pressing from the front and that then carriers on from behind."
He added: "With Pete we've been told against certain teams to defend narrow, let the ball go wide which means it's harder for them to score. So I think by doing that it's give us more of a chance to keep a clean sheet."
The 2018/19 season has seen Hamer produce consistent performances after a good run in the first team. This included recently a super strike at MK Dons in January before coming back stronger after having a few weeks out from a horror challenge against Yeovil at Boundary Park.
"Personally, it's been a good achievement for me. I'm only 19, a lot of people my age wouldn't really be playing first team football especially in the football league so it's good for me.
"Playing games week in, week out my confidence has grown. The start of the season my confidence wasn't there as I was just getting into it with the new manager and surroundings. But I'm going into every game now getting better and better."
A big part of his development over the years has been Pete Wild, someone who he realises has given him the opportunity to become a professional footballer.
"As soon as he came in he give me a chance, as well as in the FA Cup against Fulham and since he's been in charge he's played me.
"I've known him from the youth team so I know how he likes to play. So it's a big thanks to Pete!"
And with the re-introduction of Wild into the first team it can only help Hamer as the Head Coach likes to focus the back first.
"It's more the defensive side he's had an impact on. Being compact when we've not got the ball and then when we get the ball playing to the wings or the number 10.
"The spirit is there now with him. He just brings that excitement and belief that we can achieve things."
As the side look to string a set of results together to try and finish the season strongly, one of the sides above Latics at the moment is Colchester, so the team are prepared for what awaits them in Essex.
"We've done our analysis on Colchester. Before every game we have a poster of what we can do as a team with personal targets for what we've got to try and achieve during the game, so that helps us with how we play and allows us to focus on the threat from the opposition too.
"The fans play a big part in these games. When they're on your back it's not as easy to play but when they get behind you it gives you more confidence to play better, especially with the good away following we get."
