Belfast rivals Linfield and Glentoran cruised into the last eight of the Irish Cup with wins over Warrenpoint Town and Armagh City respectively.
Andrew Waterworth scored a hat-trick, with Aaron Burns and Stephen Lowry also on target in a thumping 5-0 win over Barry Gray's side at Windsor Park.
Steven Gordon, Stephen McAlorum, Curtis Allen and Fra McCaffrey were the scorers as Glentoran beat Armagh 4-1.
A superb Stephen Murray strike earned some consolation for the visitors.
The Blues were quickly into their stride as Burns took advantage of poor defending, taking one touch and finding the corner of the net after meeting Grant McCann's 10th-minute corner.
Burns was then denied by Jonathan Parr, who also made good saves from Jamie Mulgrew.
Waterworth grabbed his first when he beat the offside trap, pulled the ball round Parr and tucked into the empty net.
The home striker was on target again in the 83rd and 87th minutes, with Lowry completing the rout in added time.
Across in East Belfast, Glentoran immediately assumed control against their Championship One opposition as Gordon had an effort saved and Jordan Stewart saw his header cleared off the line.
The hosts had to wait until the 50th minute to open the scoring however when Gordon fired home after the ball fell kindly to him following an Allen free-kick.
McAlorum's speculative cross drifted over the goalkeeper and into the net soon after, then Allen latched onto a good through ball to convert the third in the 69th minute.
Murray's 78th-minute goal gave Armagh some hope but Fra McCaffrey popped up with his eighth of the season after combining well with fellow substitute David Scullion nine minutes from time.
