Great Britain slumped to a 44-19 defeat by a strong Bosnia-Herzegovina team at the World Championship qualifying tournament in Finland on Saturday.
At half-time the inexperienced GB side only trailed by five goals but they ran out of steam and tired after the break.
"Once we started changing our starting line-up we lost our shape," said assistant coach Bill Baillie.
GB, who lost to Romania in their first game, hope to finish with a win against hosts Finland on Sunday.
"We're still optimistic of beating Finland, having seen them play yesterday, so hopefully we can go out on a high," said Baillie on Saturday.
Steven Larsson top scored for GB with six goals, while John Pearce added three.
