With the destination of the Davis Cup determined, the professional tennis season has come to a close. Thus, we begin our look back at 2017, a memorable year on and off the court. Our Top 10 On-Court Moments, and our Top 10 Off-Court Moments, will remind you of everything that transpired.

All the complaints about the sport's crowded schedule didn't stop organizers from shoehorning even more events into the season in 2017. They often involved new types of competition, blurring the line between exhibitions and tour events.

There was the Laver Cup, run by Roger Federer's management company, which featured Europe vs. The (Rest of the) World in a three-day team competition that memorably saw Federer and Rafael Nadal team up in doubles for the first time. The ATP also introduced the NextGen Finals for the top under-21 players, and is considering a re-launch of its World Team Cup.

Even the Davis Cup, which had a move to best-of-three sets narrowly voted down and shelved a neutral location for the final, is planning to trial new set-ups such as best-of-three-set singles matches with best-of-five-set doubles match, or even two-day ties.

On the other hand, some recently introduced events showed the difficulties involved in establishing themselves. The International Premier Tennis League (IPTL) is not being held this year, with some teams experiencing financial problems, and the India-based Champions Tennis League has been formally suspended by those involved in running it.

But the staunchly traditional sport can't be accused of not going with some different looks every now and again.
