Andy Murray has sauntered his way through the Australian Open and, you know what, he might have a chance of winning the thing.
Who would have thought that a couple of months ago on the back of an embarrassing 2014 season? Not me, but I'm happy to admit that I could be wrong.
One of the key low-points for the British no.1 last season was a heavy defeat as reigning champion at Wimbledon's quarter-finals against Grigor Dimitrov. For that reason, Murray's morale-boosting marathon win over the Bulgarian will have an extra special feel to it.
Nick Kyrgios awaits in the last-eight. The young Australian will certainly have his home crowd vociferously behind him in their encounter, but the powerful teenager is prone to poor concentration and question marks will remain of his ability to stay cool in testing moments - Murray will be the favourite.
If the Briton can progress past Kyrgios, and also the winner of Rafael Nadal's and Tomas Berdych's tussle, the 27-year-old will find himself in the familiar territory of an Australian Open final - most probably against Novak Djokovic.
It will perhaps be the ultimate act of revenge and relief if he can finally master Melbourne after three previous final defeats. At the moment, you wouldn't bet against it either.
So what is different for the Scottish-born star now?
Even since before Christmas, Murray has seemed more jovial, fresher and happier in general - sorry to the legion of tennis fans who claim he is the most-boring-ever - it's certainly paying off on-court too.
You have to look at what has changed. Amelie Mauresmo's coaching techniques? - Nope, he was still pretty poor with her last season. Although the camp may be a tad more settled after Dani Vallverdu's exit; it wasn't all happy families.
The biggest change has been in his love life. Long-term lover Kim Sears is finally set to make a man out of Murray after the former world no.3 proposed in December. Perhaps he's trying to copy Djokovic, who also got married recently.
Now, Murray doesn't really seem like the type who would get excited about a wedding. He seems like the type who would purposely mess-up his limited responsibilities in the matter to get out of doing them. However, speaking on-court after beating Dimitrov, he seemed well up for it.
When prompted, Murray even made a joke about 'freeballing'. For those not attuned to 'freeballing', they were talking about full kilts. When asked if he would wear one, Murray said: “Yes, obviously, proper kilt.”
It really is great to see this new-Murray, and it appears fiancee Sears has done a marvellous job in getting her man back to his best. Lots of cuddles, that is what it must be down to.
Lets just hope this new-found sense of joy will propel him all the way to the Australian Open title, finally.
