Stefanos Tsitsipas reached the fourth round at Roland Garros before falling to Stan Wawrinka in an epic five-setter.

Tsitsipas, Felix Lead Race To Milan

Kecmanovic currently clinging to seventh and final qualification spot

The top of the ATP Race To Milan remains unchanged, but the competition for the final qualification spot has become increasingly tense with five months to go until the Next Gen ATP Finals in Milan.

Reigning Next Gen ATP Finals champion Stefanos Tsitsipas, 20, and 18-year-old Canadian Felix Auger-Aliassime lead the Race, which will determine seven of the eight 21-and-under players who compete at the tournament. The eighth position is reserved for a wild card. Tsitsipas has a whopping 2,985 points, while Auger-Aliassime has 1,081 points.

Tsitsipas won his first ATP Tour clay-court title last month at the Millennium Estoril Open (d. Cuevas), and Auger-Aliassime made his second ATP Tour final of the season in Lyon (l. to Paire).

Right behind Auger-Aliassime is countryman Denis Shapovalov (795 points), who made the Lyon quarter-finals and competed this week, alongside Auger-Aliassime, on grass at the MercedesCup in Stuttgart. American Frances Tiafoe (750 points), who reached the third round at the Mutua Madrid Open, is in fourth place.

Further down the Race leaderboard, Serbian Miomir Kecmanovic currently holds the seventh and final qualification spot with 392 points. But a pair of 20-year-old #NextGenATP players made gains at Roland Garros and are close behind the 19-year-old Belgrade native.
