PHIL PARKINSON bemoaned a lack of ruthlessness from promotion-chasing Wrexham after suffering a 1-0 defeat to Doncaster Rovers at The Eco-Power Stadium.

Grant McCann's side came flying out of the blocks and were the better team in the opening period, with Rovers taking the lead in the 44th minute when Owen Bailey headed home a cross.

Parkinson felt Wrexham improved after the break and Paul Mullin had a goal ruled out for offside while substitute Steven Fletcher saw his injury-time header brilliantly kept out by Rovers goalkeeper Thimothee Lo-Tutala.

But that was the only save of note by the Doncaster custodian and the Reds' boss was disappointed he wasn't tested more, with a lack of cutting edge in the final third leading to defeat and keeping Wrexham third in the League Two table with five games remaining in the quest for a top-three finish.

"Chances to work the goalkeeper, we didn't do that enough," said Parkinson.

"It was a night for really shooting low on this greasy surface. We had a couple blazed over the bar in the first half.

"You need those decisive moments and we didn't have them. As I said to the lads in there, that is not good enough.

"We were better at Grimsby with a real clinical edge, but we were too loose in and around that final third for my liking.

"Crosses overhit and set-play delivery not quite right, I just feel it's being at it and being really focussed to make moments count and we have got to be disappointed that when we had those moments, we didn't test the goalkeeper enough.

"It is as simple as that."

Leading scorer Mullin, who bagged a brace in the 2-0 win over promotion rivals Mansfield Town on Good Friday, thought he had scored his 100th goal for the club when a corner has touched on by Eoghan O'Connell and the striker pounced from close range but it was disallowed for offside.

After watching a repeat of the 'goal' back following the final whistle, Parkinson felt Mullin might have been played onside.

"We still had moments to have shown a bit of ruthlessness to get us ahead or get us back in the game," said the Reds' boss.

"On the balance of the second half, we deserved something from it. We had some good moments.

"Fletcher's header is really unlucky and the disallowed goal, if Mullin lets it run it is a goal.

"But fair play to him if you look at it, there's a lad on the linesman's side looks like he has played him onside.

"I think it is a very close call. Close call's happen but it went against us.

"We needed something to go for us and it didn't."

If O'Connell's flick had found the net without Mullin getting a touch then the goal would have stood but Parkinson completely understood why his star striker wanted to make sure. 

"It was striker's instinct really," he added.

"Mulls wasn't sure whether the backheel was going in so he has tapped it in."
