Tim Vaughan's seven-year-old was all out to old Bobbie's Diamond by three-quarters of a length after a three-horse affair soon became a duel, from which the 4-9 favourite just came out on top.
"It's fantastic. 100 winners is always the initial target but then it moves on to 150 which I'm delighted to achieve," said Johnson.
"There's not one person or one horse that can make it happen and I couldn't do this without the fantastic support of all the owners and trainers. It's a big team effort and I'm lucky to be a part of it.
"The Stobart Jump Jockeys' Championship title is in my sights but Harry Skelton and Brian Hughes are riding very well so I'll just aim to stay healthy and keep riding winners - that's always the aim of every season and I'm lucky to have a lot of support and to be enjoying it."
