The 23-year-old was completely unaware of his unique stat, saying he was more focussed on killing off the match.
"It was quite pleasing just to be able to get us across the line," Hobson said.
"I kind of lost track of my score, we were playing a bit of cat and mouse on day two, turning over the strike and trying to kill the game, so I didn't even realise I was close to a hundred.
"We've had a few losses in finals before and lost the Prelim Final last year, so it was just awesome to get through to the Grand Final."
While Hobson has been consistent this season, scoring 728 runs (third overall) in 18 matches at an average of 52 (second highest), he was still wary of Melville's formidable bowling attack.
"To be honest, I don't really think about it (personal score)," he said
"Melville are a quality team, so when they got posted their score, I knew it would be hard work. I felt like I'd been hitting the ball alright but certainly didn't expect to score a hundred before the match."
After making his debut in the 2011-12 season where he played nine games, Hobson blossomed into a key playmaker for the Tigers, playing no less than 13 matches in each season since.
"I would say staying on the park injury wise has helped me be consistent," he said.
"I think it's probably the coaches at the Tigers too. We've had Jim Allenby and Tim McDonald over the last few years and Jim in particular has been absolutely terrific and been a real mentor for me and for the young batsmen around the club. He puts in a lot of work with the young guys at the club and he doesn't over complicate things.
"It also helps having real good depth in the batting line up which takes pressure off the individual. We bat down to nine pretty much and we're really lucky to have Jim come out at number seven, so it makes it harder for teams to wrap up our tail."
With the attention turning to this week's Two Day Grand Final, Hobson believes his side has learnt some valuable lessons during the Elimination Final loss to University.
"It was probably a good loss to have just to refocus," he said.
"I think some of us might have been still in One Day mode, having the One Day Grand FInal the week before, so we probably didn't apply ourselves as well as we should have.
"That kick up the backside was probably a good thing, it was tough batting conditions and they bowled really well but I think we could've handled it a little better."
And as for claiming an elusive double Grand Final win?
"It would be awesome, I'd be absolutely rapt," he said.
"The main group of guys have been playing together for the last few years, I've been through juniors with a lot of them too, so it would mean a lot.
"In my second year, we lost to Wanneroo and you just don't realise that you might not get there again, you think yeah we'll be around the mark. We've played so much cricket together and it'd be awesome for us and the club."
The Grand Final between Claremont Nedlands and University takes place on Saturday March 24 at 10:30am at the WACA Ground.
