Alexander Zverev has a comfortable lead in the Race to Milan standings, but he has a new challenger atop the ranks: Borna Coric.

The 20-year-old won his maiden ATP title in Marrakech on April 16, defeating veteran Philipp Kohlschreiber in a tense three-set final. The Croatian saved five match points in the Grand Prix Hassan II final, becoming the third Next Gen star to lift a trophy on tour.

He was eighth in the Race to Milan on April 3, but after a breakthrough month he’s now second behind Zverev.

Zverev (700 points), in first place, leads Coric (435) by 265 points. Rounding out the Top 5 are Daniil Medvedev (315), Hyeon Chung (293) and Ernesto Escobedo (281).

Chung, who had to qualify for the main draw in Barcelona last week, moved up six spots after reaching the quarterfinals. He also moved up 16 spots in the ATP rankings to No. 78.

The top eight Next Gen players—ranked 21 and under—will qualify for the first-ever Next Gen ATP Finals. The tournament will take place in Milan from Nov. 7-Nov. 11.



20-year-old Russian Karen Khachanov moved up 14 places in the ATP tour rankings to a career-high No. 42. He reached the quarterfinals in Barcelona before falling to Horacio Zeballos.

Speaking of Zeballos, he shot up 21 spots to No. 63 with his semifinal showing in Spain. The 32-year-old Argentinian hadn’t advanced to the semifinals in an ATP tournament since 2013.
