Volkswacht Bodensee - Alcaraz grinds past Shelton to reach Roland Garros last eight

The Spaniard emerged victorious 7-6 (10/8), 6-3, 4-6, 6-4 after over three hours of blistering serves and power-hitting on Court Philippe Chatrier.

Another American awaits Alcaraz in the last eight after 12th seed Tommy Paul earlier defeated Alexei Popyrin in straight sets.

The four-time Grand Slam winner edged a tight first set, which produced only one unconverted break point, at the end of a lengthy tiebreak that saw both players have chances to clinch the opener.

When Alcaraz finally forced a break against the big-serving Shelton in the second set, it was enough for him to move into a two-set lead.

But once again Alcaraz failed to see out a straight-sets victory as Shelton produced two breaks of serve to edge the most open of the four frames.

The 22-year-old nonetheless bounced back to gain the advantage in the fourth set, before serving out as dusk descended over centre court.
