Gut-wrenching contest. Excellent drama, ridiculous choking and safe CC/slicebotting interpersed with massive Thiem shots, great gets on both sides and great Schwarrtzy droppers. Every set could have been won by the other player. Early on, Thiem kept getting into Diego's service games, but failed to create another break and plonked the breaker; Schwartzman had Thiem on the ropes in each of the last three sets but could never finish - massive choke in the second set but Domi came up with some epic stuff in the last two sets alright, particularly when Schwartz had 40-0 to take it to a fifth set, but still lost the tiebreak. Unfortunately, Thiem finally succumbed in the end, losing 14 of the last 17 points, the last two to netted dropshots. Schwartzman will now have two full days to recover, so he should be fairly fresh to likely face The Nadal in the semifinals.
