AO'13 4R 6-setter loss to Djokovic, an emergence of GS Stanimal.I might be biased as a Swiss, but I think Wawrinka somehow deserves to be included in the list. I see that it is difficult to single out one of his three slam wins, but rising from being a typical 10 to 20 ranked player to winning three slams with 5 wins over the big three included is for me one of the best stories of recent tennis history.
If I have to chose one match, it would be the French Open final against Djokovic. That was insane shotmaking.
AO'14 QF 6-setter win over Djokovic, beginning of Stanimal's GS domineering together with Djokovic.
RG'17 Wawrinka-Murray SF 5-setter that virtually stopped their GS careers.
