Callum Davidson watched his Queen's Park side suffer a third successive league defeat
Queen's Park crashed back to reality after their Scottish Cup heroics as Hamilton secured their first away win in the Championship since November.
Scott Robinson, on his Hamilton debut, netted the opener on five minutes.
Just eight minutes later Ricki Lamie grabbed his first goal for Accies to double his side's lead.
Sean Welsh pulled the hosts - who knocked Rangers out of the Scottish Cup last weekend - back into the match with a volley.
But Callum Davidson's side could not find a leveller and drop to sixth as Hamilton rise out of the relegation play-off spot to eighth.
