On the center’s hard-indoor surface, only Mārtiņš Podžus managed to overpower Aleksander Lazov on Friday in the singles sets, while his brother Jānis Podžus relinquished his set to Dimitar Kuzmanov the same day.
On Saturday the brothers lost to Tihomir Grozdanov and Ilia Kushev in the doubles set.
During Sunday’s reverse singles set Kuzmnaov defeated Mārtiņš Podžus, leaving Latvia ranked 42nd in the Davis Cup lists against Bulgaria in 63rd position.
Last year Latvia slipped from the Zonal Group I category to Zonal Group II and must now face Madagascar in July to hold on to its current level, while Bulgaria moves on to face Luxembourg.
