Novak Djokovic has won a record 30 ATP Masters 1000 titles, and somehow, only one has eluded him. He has never won Cincinnati. Unfortunately, the 30-year-old won't get another shot this year as he ended his season in July with an elbow injury.

It adds yet another dark spot on his Cincinnati career, which has unfolded in dramatic fashion: 

'08

This was the first year Djokovic got beyond the second round at the Ohio Masters tournament. He left his previous Cincinnati career record of 1-3 in the dust by reaching the final. Despite knocking out Rafael Nadal in the semifinals, he lost in the final to Andy Murray. 

'09

The next year, Djokovic defended his final run without dropping a set and once against taking out Nadal in the semifinals. He fell to Roger Federer in the final quite anti-climatically, 6-1, 7-5. 

'10

The final showing run ended at two with Djokovic losing in the quarterfinals. Ranked No. 3, the Serb was upset by Andy Roddick.

'11

In 2011, Djokovic returned to his third career Cincinnati final in what was one of his best seasons ever (three Grand Slam crowns and his first time ascending to No. 1). Again he was up against Murray, but this time he retired with a shoulder injury while down set and a break. 

'12

Another year, another Cincy final for Djokovic, and again without dropping a set. He faced another familiar final opponent, Federer, and dropped the match in straight sets.

'13

For only the second time in six years, Djokovic failed to reach the final. He was stunned by John Isner in the quarterfinals. 

'14

Things turned out even worse for Djokovic in 2014. In his worst showing since 2007, he dropped out in the second round to Tommy Robredo. Djokovic was No. 1 at the time. 

'15

This may have been the closest Djokovic came to holding the crown. He still lost to Federer in straight sets, but at least had some looks at winning the first set in the 7-6 (1), 6-3 loss. 

Djokovic would skip Cincinnati in 2016 after a heartbreaking loss to Sam Querrey at Wimbledon. This year, he's gone one step further by opting to miss the rest of 2017 after retiring from the Wimbledon quarterfinals.

Is a Cincinnati title ever going to be in Djokovic's future? The world will have to wait another year to find out.
