As Kyle Edmund fell to the court of the Pat Rafter Arena and clutched his right ankle in pain, even the British supporters must have wondered if they would make it out of Brisbane without picking up an injury.
It was a tense match that went with serve for the most part, with Dimitrov earning the only two breaks - one in the first set and one in the last - on his way to victory. "I really hope he gets better".
Dimitrov terminated a long rally on the first point with a lunging backhand volley and then chanced a forehand drive which grazed a sideline on the second. Two games later, the defending champion had secured his spot in the Brisbane International semifinals.
"I'm feeling pretty good".
"First match in about a month - I feel a little bit rusty, but at the same time I'm excited and trying to get into a rhythm".

Belarusian qualifier Aliaksandra Sasnovich reached her first tour-level final with a 7-6 (3), 6-4 semifinal win over seventh-seeded Anastasija Sevastova. The Australian number one admitted he was flat at the start of the match before switching on at the start of the second set.
"I will look to fly to Sydney and I'm ready to pick myself up and go again, " he said.
"As bad as it is to say, it's kind of like a tap. I can turn it on when I want to and turn it off".
De Minaur will play unseeded American Ryan Harrison for a place in the final. The 18-year-old de Minaur stunned fourth seed Milos Raonic in the second round and there was no letdown Friday as he ousted USA qualifier Michael Mmoh 6-4, 6-0 to reach his first ATP semi-final. Istomin advanced 7-6 (5), 6-2 over Jared Donaldson and Harrison had a 6-7 (5), 6-4, 6-2 win over Yannick Hanfmann, who was a late addition to the draw after Andy Murray withdrew.
