"If I'm not ready now, I'm just never going to be ready. I feel in two months I'll be way better than I am now...you have to start somewhere..." is what Serena Williams had said about her comeback to the Abu Dhabi exhibition event.

She equates her comeback from injuries as just like coming back from surgery saying "I have plenty of comebacks, from injuries, from surgeries, but I've never had a comeback after actually giving birth to a human..." The comeback now has Serena fight the weight gain, the birth and its complications to a sport that she had missed in about a year and that much wa expected from her.

She is still trying to put the pieces together carefully. Maria Sharapova was doing great until she failed the drug test. She wasn't out of shape or injured but Sharapova lacked the top notch skill it takes from being banned from playing and many had hinted that now she'll have to struggle and play not being under the effects of Meldonium.

The Russian's comeback was at the Porsche Grand Prix in Germany and she did fairly well in April 17, 2017. She mad it to the semifinals, was denied a wild card to Roland Garros but received one for Madrid of which she fell in the second round to Eugenie Bouchard and Rome bowing to a left thigh injury.

She had to give Wimbledon a miss because of more injuries and the Stanford Classic, Sharapova retired in the second round due to injuries again. She wasn't the same and the comeback still wasn't complete even though at the Asian swing with theTianjin Open she did finally win a title back in October of 2017 defeating Aryna Sabalenka.

The Russian was knocked out at the opening round of Indian Wells by Naomi Osaka and she will not be present at the Miami Open due to a forearm injury. She has more time on the injured list than on the court and where her career will go now is uncertain.

Top ranking men in tennis has had miserable times with surgeries and injuries. Andy Murray trying to recover from hip surgery. Novak Djokovic suffers chronically with an elbow ailment and doesn't want to have surgery fearful that his comeback will be extended.

Stan Wawrinka has had knee surgery and did play a bit making a resurgence at the 2018 Australian Open but wa disposed of by Tennys Sandgren in the second round. Stan hasn't played since Wimbledown and lucky tohave gone till the second round.

But tournament directors say it's Wawrinka's shoulder now. Before the shoulder flareup he'd said "I'm really, really happy to be back on tour and seeing the sun...the first thing is to play a match, to play a tennis match again".

It wasn't long that the shoulder started and his comrades go down one after another not able to make a complete recovery, so did Rafael Nadal withdraw from one of his favorite events in Acapulco, then Indian Wells and now the Miami Open.

He commented that "It was very painful to retire from Acapulco and it's very hard...to not play in the USA...I will miss you and I will do everything that's possible to be bak there in 2019". It's his legs and knees, but basically his hip which is the trouble and stopping him from completely healing and getting back on the court.

Japan's Kei Nishikori has been plagued by injury and made his comeback at the premiere event New York Open where he did run deep into the semifinals. Afterwards he wasn't feeling well and had to withdraw from Indian Wells from an illness.

The complete comeback for players it seems is always uncertain. It's like a rollercoaster of trying to heal and get back on court and thinking it's complete then a flare up. The expectations on themselves and the tennis community wanting to see them back is not only physical stress but emotional.

Comebacks are difficult because players are fighting to not only get back on court, but to perform like they did before illness and injuries which unfortunately is a battle at many times they will lose.
