Tuesday’s 2-0 win at Albion Rovers, courtesy of goals from James Hilton and Joao Victoria ensured they finished in the top five ahead of the split.
That means they will battle it out with rivals Edinburgh City, Stirling Albion and Elgin City for the top four finish which would secure a place in the end-of-season play-offs.
"We were relentless,” said Farrell. “I don't think anyone could have begrudged us if we'd been further ahead at half-time and that was my only concern, the chances we missed in the first half.
"We created numerous chances. We just told them to keep going and make sure we didn't concede second half and I thought our shape was good.
"We defended well and got a second goal to kill the game off, which was pleasing.
"There are three other teams vying for that top four place though and we're all as committed as each other so it's going to be really competitive with four good games to look forward to."
First up for the Blues is Queen’s Park on Friday night. And although Ray McKinnon’s side don’t need to bother with promotion play-offs after winning the title, Farrell doesn’t expect them to relax.
He said: "I expect Ray will want to go through the season unbeaten. That will be his driver now.
"They've ticked off the first thing they wanted to do, which is win the league and get promoted so they'll now be trying to go through the season unbeaten.
"We know it's not going to be easy, they're a good side and deserved winners of the league.”
Away from the league, Stranraer’s Scottish Cup run was ended, as expected, by Hibs at Stair Park last Saturday. But the Blues boss was proud of his players’ efforts in the 4-0 defeat.
He said: “I thought we acquitted ourselves really well. Hibs said that as well, Jack Ross was kind enough to say that.
"But they're third in the Premiership for a reason; after Celtic and Rangers they're the best team in Scotland and at times they proved that on Sunday with their quality and movement.
"But I thought we did really well. We stayed in the game at 1-0 with 65 minutes played.”
