Boro started well despite a very difficult pitch, but chances were far and few between as both teams struggled to get any sort of rhythm.
After 20 minutes Athletic were hit with a blow when striker Oliver Hesketh had to be carried off having sprained his ankle.
Josh Dolan replaced him and made an immediate impact, chasing down a back-pass to the Hessle keeper and just managed to slot home to make it 1-0 to Boro at half-time.

Owen Lambert made a big difference when he came on, scoring Scarborough’s third, making the score 3-1 to the away side going into the break.
Into the second half, Scarborough were always on the front foot and were awarded a penalty when Lambert was tripped in the box.
However, Nathan Williams missed from the spot.

Scarborough added a fifth with another strike from Williams, meaning the game ended with a 5-1 win for Boro.
Scarborough Athletic Under-13s played Swanland at home.
The first half was tight with both sides looking to attack quickly but lots of good defending from both teams kept chances to a minimum.
Just before half-time Swanland took the lead, a well-taken goal by their pacy striker, who drove past a couple of Boro defenders then slotted past the advancing keeper.
The second half started with Boro dominating the midfield, with some excellent passing and forward play.
This resulted inthe home side levelling the scores through Cameron MacDonald, as he latched onto a through-ball from the impressive Archie McNaughton to fire into the goal.
Although Boro were now dominating the possession, they fell behind again to two more well-worked goals from the Swanland number nine, who was proving a handful.
Taylor Hide then scored a fantastic goal for Boro, picking the ball up on the half turn, advancing forward before lashing the ball into the bottom corner from the edge of the area to reduce the deficit at 3-2.
After getting back into the game, Swanland quickly regained their two-goal lead as the visitors played a quick ball forward, which resulted in a mix-up in the Boro defence, allowing the Swanland player to nip in and find the back of the net.
Boro were controlling possession with plenty of good play in the midfield areas and a great pass from the Athletic man of the match Hide found MacDonald, who again beat the Swanland keeper to set up an exciting finish.
Lots of chances were created by Boro, with Kene Knowles going close on several occasions, Caleb Sheader missing a good chance and Lewis Hunter having a goal disallowed for offside as Swanland held on for a 4-3 win.
It was a very good display from Boro despite the result.
Coaches Chris Kendell and Andy Hide were happy with the performance and congratulated their players for the development they are showing and sportsmanship they showed at the end.
Scarborough Athletic Under-15s returned to league action this week with Beverley Town the visitors at the Flamingo Land Stadium.
With Scarborough kicking into the wind, they found the going a little tough with Beverley having more of the ball and creating a number of chances early on.

However ,Beverley took the lead midway through the half with a neat finish which Chapman could do nothing about.
The first half ended 1-0 Beverley with their keeper not really tested.
A few words of encouragement at half-time seemed to inspire Boro to a fine second-half performance.
A corner swung in from Liam Coulson found centre-back Connor Avison at the far post to strike home from close-range.
With Scarborough on top and searching for a goal, it was Beverley who took the lead with 15 minutes remaining against the run of play.
Scarborough weren’t finished though, a fine passing move involving four Scarborough players led the ball to be fed out to winger Aaron Holdsworth, and his powerful drive into the bottom corner from the edge of the box brought the score to two each.
With a few minutes remaining, Scarborough got a free-kick deep in the Beverley half, Coulson again swung in a beautiful ball, which found Avison, the defender played it back into the box for midfielder Reuben Staveley to nod home from two yards out and get the victory for the home side.
