Sam Walker came from behind to shake off three determined opponents and qualify for the main draw at the Austrian Open in Linz – where he will play Japan’s Koki Niwa.

Having overturned a 3-1 deficit to beat Samuel Kaluzny of Slovakia yesterday, Worksop ace Walker twice came from a set down to see off Simon Pfeffer of the host nation in his second group match today.

That ensured he topped the group, putting him in to the knockout stages – and he followed with a preliminary-round victory over world No 159 Tomas Tregler of Czech Republic to move into the last 64, where his opponent will be world No 19 Niwa.

In the under-21 singles, Walker, seeded No 4, overcame a potentially tricky match in the last 64 against Romania’s Cristian Pletea. His opponent is the No 16 junior in the world but Walker always had the edge to win in three straight. He next plays Japan’s Yuma Tsuboi.
