BIG John McCombe made his senior debut in the same match as David Mirfin almost two years ago.
But while Mirfin has now clocked up a half-century of League appearances, McCombe has had to wait long and patiently for his two starts so far.
Having this week forced his way into manager Peter Jackson's starting line-up, however, McCombe is determined to make up for lost time.
The powerful teenager - built like a brick out-house - wants to do well, earn a new contract and then prove he's worth a regular first-team place.
"I'm really happy to be involved at the moment and I think I've done all right," said McCombe, who starred as a substitute at MK Dons before starting against both Blackpool and Tranmere.
"The MK Dons game eased me into things because I was on for quite a long time (64 minutes).
"Then to play the full games against Blackpool and Tranmere has now given me more confidence to know I can play at first-team level. It's great as well to have had so many lads around me who I know well.
"I've played alongside Nathan Clarke, David Mirfin and Tom Clarke a lot at Junior and Reserve level, so I know their strengths and their weaknesses.
"We all feel that if we can stick together we can go a long way.
"We are all friends who have come through together at the club - lads like Jon Worthington, Andy Holdsworth, Adnan Ahmed and Anthony Lloyd as well - and for people who have been together since a very young age it's great to play in the first team.
"It has all felt very familiar, seeing so many faces I'm used to, and it has made it easier playing alongside lads I know so well."
McCombe (pictured) is hoping to follow in the footsteps of brother Jamie, who has forged a solid career for himself at Lincoln City.
"I didn't know I would definitely be playing against Blackpool last week until the Friday morning," said McCombe.
"I had an inkling that because I'd played well against MK Dons that I might have a chance and, when I wasn't involved in the midweek Reserve game against Darlington, I really began to think my chance had come.
"I was a bit nervous when I realised I was playing, but as soon as I got on the pitch I was fine.
"To come through the game with a clean sheet was great as well and, after that, I would have been disappointed not to keep my place at Tranmere, even though there is very strong competition for places here and no-one can expect to get picked from game to game."
McCombe has been working hard in the gym to build up his strength, but it's his simple approach to the game which particularly impresses Jackson.
