The Saints will hope to maintain their lead at the summit of the league with a positive result against UCD, as Sligo Rovers host Dundalk at the Showgrounds
The fixture was rescheduled after it was postponed due to a waterlogged pitch and Baraclough is seeking inspiration from the last time the teams met at Oriel Park, where the Bit o' Red triumphed 3-1.
"I think both teams will see the game as a big opportunity," he told the club's official website. "We gave ourselves a great platform in Oriel Park earlier in the season, we moved the ball well and were very clinical in front of goal to earn a 3-1 win.
"They will come here with no fear and play football and that should make it an entertaining game," added the Sligo boss.
Lee Lynch will be unavailable for the hosts, while defender Evan McMillan is also out of the tie. Striker Danny North is still not ready for a return to competitive action.
Dundalk, meanwhile, must contend with just one absence, as Chris Shields remains sidelined with a knee injury.
Sligo Rovers were overtaken at the summit of the Premier Division table by St Patrick's Athletic and the Saints can maintain their lead at the top of the table when they host UCD at Richmond Park.
Liam Buckley's side will have a full panel to choose from as they look to continue their 12-match unbeaten run in all competitions. However, Buckley remains cautious of the threat posed by Martin Russell's side, who are unbeaten in their last four league games.
"UCD have had a tremendous month of results lately," he said ahead of the tie. "They've beaten Shamrock Rovers, Derry, Bohemians and had a great win against Dundalk on Friday. They are no pushovers and Martin Russell has them playing well and passing the ball well.
"That being said, we're in good form too so it really does augur well for a good game of football."
Sligo Rovers take on Dundalk at the Showgrounds, with the game kicking off at 19:45 BST. St Patrick's Athletic will host UCD at Richmond Park, kick off 19:45 BST.
