Great Britain took a big step towards next year's Davis Cup qualifiers as Cameron Norrie and Arthur Fery both won to give them a 2-0 lead over Poland.
World number 34 Norrie survived a scare against world number 545 Tomasz Berkieta to win his nation's opening World Group 1 match 7-6 (11-9) 6-4 in Gdynia, Poland.
Fery, ranked 227 in the world, then battled to a 6-4 6-2 victory over Olaf Pieczkowski, ranked 484.
The 23-year-old was making his Davis Cup debut after British number three Jacob Fearnley pulled out with a rib injury.
