Alexander Zverev backed up last year’s breakthrough campaign with another successful season in 2018, but has yet to fulfil his potential on the Grand Slam stage.
Progress through to the French Open quarter-finals was the first time he had reached the stage in his career.
After missing out on the Miami Open title, the German enjoyed a successful clay court campaign which included wins in Munich and Madrid - the latter seeing him become only the fifth active player to win at least three Masters 1000 titles.
Zverev successfully defended his Washington title, either side of disappointing third round exits at both Wimbledon and US Open.
The talented 21-year-old has consolidated himself among the elite of men's tennis and having joined up with Ivan Lendl will now expect to make a major breakthrough in the majors.
