Although Marin Cilic defeated Diego Schwartzman earlier this year in Istanbul in straights on clay, the diminutive Argentine was determined to turn the tables on his significantly taller opponent.

Cilic, the 2014 US Open champion, and reigning Wimbledon finalist, was emphatically shown the grandstand exit by Schwartzman. The #29 seed wore down the Croat 4-6, 7-5, 7-5, 6-4 in just under 3 1/2 hours.

The Argentine took advantage of the 80 unforced errors wrought by Cilic not to mention nine double faults. It was by no means much tidier across the net; Schwartzman committed 48 unforced errors to just 30 winners.

Cilic continually played passively and it cost him. Serving at 1-1 in the first set, he missed two overheads to go down double break point then struck a forehand long to give Schwartzman a third break point. Aided by the Argentine’s errors, Cilic miraculously saved all three and held for 2-1.

In the following game, Cilic had five break point opportunities but failed to convert. In Schwartzman’s next service game, he faced two more break points but this time he was not as fortunate; the Croat converted on the second break point when Schwartzman’s shot found the net. Cilic, now up a break, held for 5-2 as Schwartzman held for 3-5.

The overhead would be the Croat’s Achilles heel as he dumped another into the net to give back the break. Cilic, at times, appeared to awake from a self-induced slumber; once alert, he began to strike the ball more aggressively, creating two break points. He would close out the set 6-4 when Schwartzman once again found the net.

They remained on serve through the first four games of the second set but Cilic once again found himself down triple break point. Though he saved two with aces, his forehand betrayed him and he lost serve.

The Croat hoped to return the favor in the 8th game when the Argentine sprayed several balls long giving Cilic double break point. His inability to take advantage was on full display when he failed to tee-off on a 66 mph second serve and as a result, did not convert the break. His perceived indifference and hesitation would continue to cost him throughout the remainder of the match.

Schwartzman, leading 5-4 was unable to serve out the set. Cilic broke back to level the set at 5 games apiece but was unable to consolidate the break and was broken following another double fault and forehand winner by Schwartzman. Once again, Cilic failed to pounce on a 64mph second serve and it costs him the second set 7-5.

The third set was no different; Cilic was erratic while Schwartzman was consistent. Cilic served first and was broken on a double fault. He would immediately break back but when serving at 2-2, threw in another double fault to drop serve. In the 8th game, Cilic went up double break point after ripping a forehand and on the next, drew an error to break serve.

Level at 4 all, Cilic was unable to consolidate the break and was broken for the third time. In keeping with the match trajectory, Schwartzman threw in two double faults and dumped serve. Following a slew of errors, Cilic lost serve and Schwartzman served out the third set, 7-5.

In the fifth game of the fourth set, Cilic went down double break point and dropped serve and would be broken again in his following service game. Right on cue, Cilic broke back for 5-3 and held for 5-4. Schwartzman would serve for the match but had to withstand three more break points before holding and dispatching the #5 seed.

At 6’6’, Cilic has a fluid, powerful and customarily reliable serve, but today it abandoned him. While he had 14 aces, he could not always produce one down break point. He was particularly ineffective on break point opportunities converting a scant 7 of 21 in addition to winning only 32% of second serve points-undeniably, a recipe for disaster.

In the end, the #5 seed was undone by passive, unfocused and uneven play while his opponent remained composed and patiently awaited his opportunities. Schwartzman will have little time to savor this most satisfying victory for up next is last year’s quarterfinalist and Nadal slayer, Lucas Pouille.
