I love Juan Martin but he really has no business being included in this big four over Murray. One fluke (yes, it was
) slam win over Federer does not negate the fact that Murray has had a lot better career results. Results are what makes a player, not what-ifs and what-mights. Delpo can claim a slam, but he still has no Masters title and has yet to follow up his slam final with another one. Murray may not have a slam, but he has a ton of other results that speak to his ranking.
