Miami, Ricky Dimon @Dimonator

First it was Roger Federer. Then it was Rafael Nadal. And the hits have kept coming at the Miami Open.

Federer withdrew from the tournament due to illness, while Nadal could not get through his first match because of issues related to the heat. David Ferrer followed his fellow Spaniard out of South Beach by losing to Lucas Pouille on Sunday night. On the women’s side, Serena Williams and Agnieszka Radwanska both lost on Monday afternoon. The carnage continued when Andy Murray succumbed to Grigor Dimitrov 6-7(1), 6-4, 6-3 during third-round action.

Dimitrov trailed 3-1 in the final set but reeled off five straight games to wrap up the victory in impressive style after two hours and 25 minutes. It was a much-needed result–and one of his best ever–for the Bulgarian, who currently registers 20 spots off his career-high ranking at 28th in the world. He had not defeated a top-10 opponent since upsetting then-No. 9 Stan Wawrinka at the Monte-Carlo Masters last spring. This is Dimitrov’s second-even win at the expense of a top-2 opponent, having previously stunned world No. 1 Novak Djokovic on the clay courts of Madrid in 2013.

“I’m happy,” Dimitrov assured. “Of course I’m happy with that victory. Every time you beat a top player you know you must have done something good.

“I played quite a few times against [Murray]. I think we know our games pretty well. I just played better in the good moments today. That’s it. I think I was just a smart player throughout the course of the whole match. Even though I lost the first set, I kept a good composure…. I think when I was 3-1 down in the third set, I really felt that I know I’m going to get another chance because I was returning well, playing very good in the key moments.”

Murray played a near-flawless first-set tiebreaker, but he struggled in the pressure-packed moments throughout the duration of the proceedings. After trailing 4-0 in the second set, he had a break point to get back on level terms at 5-5 but could not convert. The Scot also dropped his last three service games of the match without even getting to deuce a single time.

“(I made) a lot of unforced errors in the third set for sure,” Murray lamented. “Obviously (I) didn’t start the second set particularly well. After winning a close first set you obviously want to try and put your opponent under pressure. Credit to him. He was more solid than me…. Physically it was okay. I mean, the conditions were actually not that bad today. It was just humid. Obviously the cloud cover helped. It was just very, very humid. Physically I was okay.”

Dimitrov will have to be ready for another physical battle against Gael Monfils on Tuesday. Monfils has enjoyed a much more routine trek through the Miami draw, having disposed of Tatsuma Ito and Pablo Cuevas in easy straight sets. Dimitrov, on the other hand, preceded his triumph over Murray by outlasting Federico Delbonis 7-6(8), 4-6, 6-4 in two hours and 39 minutes.

Joining Dimitrov and Monfils in the last 16 were Nick Kyrgios, Kei Nishikori, Roberto Bautista Agut, and Andrey Kuznetsov.
