Rafael Jodar, 20, made Shanghai Masters history by becoming the youngest semifinalist the tournament has ever seen. The young gun punched his ticket to face Daniil Medvedev in the next round after his quarterfinal victory. Jodar's run marks a breakthrough moment for the prospect, who now gets a crack at one of the sport's most formidable competitors on a stage where the stakes don't get much higher. How he performs against Medvedev will tell us whether this is the start of something real or a one-off deep run.
