Although nothing is official yet, the writing certainly seems to be on the wall with regards to a match between CM Punk and The Undertaker at WrestleMania 29.
Punk is now outside the WWE Championship picture and Taker returned at a house show last week, so they could very well engage in one of the greatest 'Mania battles of all time.
Until that happens, however, Punk's WrestleMania resume contains just six matches.
Punk has developed into a major star thanks to his 434-day WWE Championship reign, as well as the fact that he may be the most well-rounded wrestler in the business. In a lot of ways, though, he is still searching for the defining WrestleMania moment that fans will remember forever.
Even so, Punk has certainly turned in some high-quality performances on the big stage over the course of his career.
From Money in the Bank ladder matches to singles matches low on the card to a WWE Championship encounter, Punk has run the gamut in terms of his 'Mania bouts. Knowing how important he has become to the company, I'm sure he'll add many more to the list in the coming years.
With WrestleMania 29 approaching, here are Punk's previous six 'Mania matches ranked from best to worst in terms of overall entertainment value.
