Wednesday Recap

An early break from Ungur gave him a surprise 3-1 lead over Dimitrov in the first set, but the status quo quickly resumed as the Bulgarian hit back and then held to restore parity at 3-3 before grabbing another crucial break at 5-5 to avoid the set going to a tiebreak, per Tennis TV:

Ungur came back strong in the second thanks in part to some excellent deliveries on his second serve—according to ATP World Tour, he won 67 percent of those points—and also to more ruthless returning as he won two break points to help claim the set.

Per tennis writer Ricky Dimon, Dimitrov grew visibly frustrated as it wore on:

With both players on form in the decider—they both hit some impressive backhands in the early stages—neither was able to find an advantage, and it was soon 5-5, though Ungur was required to save four break points along the way.

Per the tournament's official Twitter feed, Dimitrov was able to grab the much-needed break late on:

There would then be only one winner, as he served out the final game with ease.

Delbonis survived a similar comeback himself as he overcame Sela in three sets.

The Argentinian ruthlessly claimed the first set by taking the only break-point opportunity that came his way, but he was broken three times in just four service games in the second. An eventful final set saw both players break each other, per Istanbul Open:

It was Delbonis whose quality ultimately shone through, though, and he grabbed another to claim victory.

Marchenko's match followed a similar path, and the Ukrainian eventually overcame Gonzalez 6-3, 3-6, 6-1.

In Ramos-Vinolas' match, it was the seeded player who needed to make the comeback after he lost the first set 6-4 to Khachanov. The Russian won just one more game in the remainder of the match, though, as the Spaniard roared back into proceedings and even achieved a bagel in the deciding set.

So too was the case with Vesely and Carballes Baena as the latter snatched the close first set on a tiebreaker, per Tennis TV:

The Czech's response was emphatic, though, as he claimed the following two sets comprehensively by a score of 6-2 in each.

Vesely will take on Dimitrov in the quarter-finals. Neither particularly impressed on Wednesday, the latter especially, but their clash on Friday is an intriguing matchup that could easily go to three sets as they both did in the second round.
