The Lions assistant player-coach admitted confidence was rocked after the record 112-0 mauling at the hands of the Super League leaders and Cup holders.
But Swinton ran in 11 tries at bottom club Gateshead for a 62-16 victory on Sunday to open up a six point gap on rivals Keighley who went down at home to Rochdale.
Watson said: “The last two weekends have been really good for us.
“Our win against Oldham last week was massive and Keighley have slipped up which has opened up a gap and is a real bonus for us.
“We have had some tough physical games and I think the defeat to Warrington in the cup affected the confidence.
“But one game at a time we are getting that back.”
Mort landed nine kicks for a personal tally for a personal tally of 26 points.
Watson added: “We started off a bit patchy but once we got into our structures and kept our shape we came flying through.
“We are on a good run but we are just taking each game as it comes.
“We have a bit of a break before the Rochdale game and we will try and freshen everyone up.”
