Filip Krajinovic (6) d Laslo Djere 6-4 6-2
Krajinovic silenced any critics about form and motivation in a continuation of his brilliant run in Hamburg. After defeating Tsitipas last round, Krajinovic might just have turned a corner. Krajinovic is actually 1-0 H2H against Carreno-Busta, so has a good chance to win it.
Pablo Carreno-Busta (2) d Federico Delbonis 7-6(2) 6-3
Delbonis had a tough match ahead, likely being tired from his 3 set thriller against Benoit Paire, in which he saved 4 match points. Carreno-Busta's path was relatively straight forward, not having dropped a set all tournament. The 1st set was tight, with no breaks of serve, but it was the Spaniard turning defence into attack in a spectacular few crucial points in the tiebreaker. From there, it was all smooth sailing, earning two breaks in the second set to sweep the Argentine in another straight sets victory.
