Simona Halep finally elevating her performance at Grand Slams
• Can we compromise and say 3.5? No one would argue that Murray's achievements don't compare with those of the other three (you know, the Big Three.) But we're talking about a multi-Slam winner, who has spent years consistently going deep in the Grand Slams regardless of surface. (And I do give much credence to the Olympics which most players prepared for -- physically and mentally -- as if it were a Major.) Murray has been to seven Slam finals. Wawrinka, Del Potro and Hewitt have been to six, combined. Murray has gone almost four years without losing before the quarters of a Major. I'm prepared to err on the side of overinclusion here.
