Pablo Carreno Busta and Carlos Alcaraz save four of the five break points they face to defeat Wesley Koolhof and Lukasz Kubot on Monday in Barcelona.

Alcaraz/Carreno Busta Upset Fourth Seeds In Barcelona

Second seeds eliminated in Belgrade

Seventeen-year-old Carlos Alcaraz had never played a tour-level doubles match when he walked on Pista 2 on Monday at the Barcelona Open Banc Sabadell. However, the #NextGenATP star and countryman Pablo Carreno Busta still earned an impressive win.

The Spaniards upset fourth seeds Wesley Koolhof and Lukasz Kubot 6-4, 6-1 in 68 minutes to reach the second round at the ATP 500. They will next play one of two all-French pairs: Jeremy Chardy and Fabrice Martin or Adrian Mannarino and Benoit Paire.

Alcaraz and Carreno Busta saved four of the five break points they faced and earned four service breaks against the experienced doubles tandem.

Second Seeds Eliminated In Belgrade
Luke Bambridge and Dominic Inglot ousted second seeds Austin Krajicek and Oliver Marach 6-7(5), 7-6(7), 10-7 to reach the second round of the Serbia Open in Belgrade. The Brits saved one match point at 5/6 in the second-set tie-break. 

Aljaz Bedene and Divij Sharan took a 6-1 lead against Rohan Bopanna and Pablo Cuevas when Cuevas retired due to a left leg injury. Bopanna and Cuevas won titles together in Monte-Carlo and Vienna in 2017.
