Meet the 50-win club of the 2019 ATP season

#1 Daniil Medvedev (59-21)

Daniil Medvedev

Daniil Medvedev's early season form was hardly an indication of what was in store for the young Russian later in the season.

Medvedev reached the Brisbane final (lost to Kei Nishikori) before reaching his first fourth-round at a Grand Slam tournament, where he took a set off eventual winner Novak Djokovic at the Australian Open. A first title of the season, and fourth of his career, followed in Sofia - where Medvedev beat Marton Fucsovics in the title match.

A first career final on clay materialized in Barcelona, but ended in a straight sets loss to Dominic Thiem. The defeat in Spain kick-started a debilitating five-match losing streak which encompassed successive opening-round losses in Madrid, Rome, Roland Garros and Stuttgart, which threatened to derail a promising start to the season.

To his credit though, Medvedev managed to arrest the rot with a win over Fernando Verdasco in the opening round at Queens. A run to the semifinal at the grass-court tournament propelled the Russian to a debut in the top 10 of the ATP rankings.

Medvedev matched his best run at Wimbledon from a year ago with another third-round showing at the grass-court major. He recovered from a two-set deficit against Pierre Hugues Herbert, only to be edged out in the decider.

The youngster embarked on his North American sojourn with a run to the Washington final, where he lost to Nick Kyrgios. A week later, Medvedev reached his maiden Masters 1000 final at the Coupe Rogers, only to lose to Rafael Nadal in a lopsided title match.

In action for a third straight week, Medvedev beat defending champion Novak Djokovic in the Cincinnati semis before overcoming David Goffin in the final to become the third first-time Masters 1000 winner of 2019 (69th overall).

Earmarked as one of the dark horses for the US Open title, the young Russian lived up to the hype by beating Stan Wawrinka in the quarterfinals. In his maiden Slam semifinal, Medvedev beat Roger Federer's quarterfinal conqueror Grigor Dimitrov in straight sets to reach his first Grand Slam final.

Staring at a straight-sets defeat against Nadal at two sets and a break down, Medvedev fought back to force a fifth set. He squandered multiple break points at the start of the decider before Nadal sealed a hard-fought win for his 4th US Open and 19th Grand Slam title.

Medevedev won his maiden title on home soil by winning in St. Petersburg, and then reached a sixth straight tournament final where he beat Alexander Zverev in Shanghai to win his second Masters 1000 title.

The young Russian eventually ran out of steam as he suffered an opening round defeat at the Paris Masters. He went on to squander a match point and a double break lead in the deciding set of the round-robin match against Nadal at the ATP Finals, and ended up losing all three matches.

However, that takes nothing away from a fine season for the young Russian, whose 59 match wins and nine finals were season-leading marks.
