Portadown manager Ronnie McFall insists it is vital his team pick up another three points following their win over Glentoran on Monday night.
Goals from strike pair Gary Twigg and Darren Murray shot the Ports to within seven points of Premiership table toppers Crusaders.
Glenn Ferguson now brings his Ballymena United side to Shamrock Park – and they will be defending an unbeaten four-game run.
“They are coming off the back of a decent run,” said McFall.
“But it’s important we follow up the win over Glentoran with another three points.
“It was a big result – one that got us right back in the title mix. I’ve always said if you string together three or four wins it gets you back up with the leaders.”
Although Twigg and Murray grabbed the headlines, McFall heaped praise on defender Chris Casement and midfielder Josh Barton
“Casement is a good athlete,” he added. “When he goes down that line, he’s always a threat.
“He’s also a great striker of a ball – he can put in some quality crosses at set piece situations.”
In the absence of the injured Emmet Friars, McFall will again use Chris Ramsey in central defence along with Garry Breen.
“Friars had a scan on a knee injury, we don’t know how serious it is,” he added.
“Sean Mackle and Keith O’Hara are on the way back after injury, both of them were on the bench against Glentoran, but they need games to get their fitness levels up.”
