Injuries stalled the careers Andy Murray, Stan Wawrinka, Tomas Berdych and Jo-Wilfried Tsonga leaving them uncertain the sport, where once they had the chance to soar. In total in 2018, the four played a total of 82 matches.
Andy Murray, after the surgery of 2017, was back on court at Queen's. He played 13 matches and clearly looked like he had a lot of ground to cover before he could pose a challenge to his rivals. Wawrinka played 34 matches this year and he, too, struggled to put his best foot forward in his recuperation from injury.
Just as Wawrinka emerged as an unlikely contender to win Majors, 2019 will show if the Swiss can, too, add to his Majors' total. Berdych played 23 matches in total before ending his season early before Wimbledon. Once feared, the Czech has come to be a pale shadow of his former playing self.
2019 will tell us whether Berdych can make a turnaround, battling past injuries. Tsonga played the fewest matches: 12 and it was obvious he was not where he wanted to be. Still, it was a start and one can only hope his start will continue in 2019, as well.
