Ballymena come close to an immediate equaliser as Sean Brown's low cross eludes the in-rushing Calvin McCurry by a matter of inches.

Ballymena are slow in clearing their lines and the ball breaks to Liam Mullan who tries his luck from outside the penalty area.

He hits it well enough but it was always too high.

Ballymena roar for a penalty for handball as Sean Brown's cross deflects off Caoimhin Porter.

Referee Evan Boyce remains unmoved.

We're back underway with the same personnel who finished the first period.

A reminder that away goals do not count in this two-legged tie.

If the side are still level after the two games, the tie will be decided by extra time and penalties if necessary.

It's all square at the break after a first half of few clear-cut chances.

The best fell to Ballymena's Fraser Taylor whose shot came back off the inside of the post.

Institute come close again as the ball is played in to Caoimhin Porter whose shot is deflected behind via a vital interception from Steven McCullough.

There will be a minimum of one minute of additional time.

Fraser Taylor's through ball almost finds Alex Gawne but Institute defender Conor Quigley makes a timely intervention at the expense of a corner.

It's all a bit helter-skelter at present - no player from either side can put their foot on the ball and pick a pass.

Best chance so far for Institute as they work the ball patiently to right-back Caoimhin Porter whose long-range drive is tipped over at full stretch by Sean O'Neill.

It's a great save from the veteran Ballymena keeper.

Noah Stewart wriggles his way into the Institute penalty area but, with better options in the middle, he goes for goal himself and his effort hits the side netting.

Ballymena have asked most of the questions in this opening 20 minutes.
