Argentina's del Potro broke world No. 8 Dimitrov in the opening game of the match. Dimitrov saved a break point chance in the third game before he broke back del Potro a couple of games later to make it 3-3. As no more breaks of serve were seen, the set went into a tie-break.

Dimitrov took a 5-4 tie-break lead after overturning an early 3-1 deficit. Del Potro regrouped by winning the next two points to take a 6-5 lead.

Dimitrov saved the Argentine's set point before he converted his first set point at 7-6 to take the opener. It took over an hour for the first set to come to an end.

Both players held on to their serves until the sixth game of the second set. Del Potro again broke Dimitrov first to take a 4-2 lead. Del Potro blew a 5-3 lead as Dimitrov won four games in a row to seal the win in style.

Dimitrov broke del Potro three times and saved 5-of-7 of the Argentine's break point chances during the match. Del Potro paid the price for being unable to capitalize on his leads. The match came to an end after exactly two hours of play.

The head-to-head record between the two now stands at 5-2 in del Potro's favor. However, the last two matches went Dimitrov's way. Dimitrov, who was struggling to beat del Potro, defeated the Argentine for the first time this past August at the Cincinnati Masters.
