Port Vale's unbeaten league run stretching back to January was brought to an end following a 1-0 defeat away to Derek Adams' Morecambe side.
Adam Phillips’ 76th-minute penalty proved the difference in a game of few chances as Vale were beaten in the league for the first time in 12 games.
John Askey's side started much the brighter of the two sides, controlling possession and looking the more likely to score the opening goal.
Despite almost 75% of the first half possession, Vale were limited to few chances throughout the entirety of the 90 minutes, with a deep-lying albeit well organised Shrimps defence holding firm in the face of extended spells of possession.
Devante Rodney was once again a key focal point for the Valiants, with both he and Worrall combining well in switching play and splitting the Morecambe back line on a number of occasions.
Morecambe started the second half brightly, enjoying significantly more of the ball than the opening 45 minutes.
With the game looking destined for a 0-0, Morecambe were awarded a dubious penalty by the returning match official Bobby Madley, who adjuged Brisley to have pushed in the box despite what appeared to be minimal contact.
Adam Phillips stepped up for the Shrimps, firing past Scott Brown on his 500th EFL start to gift Morecambe the lead with less than 15 minutes to play.
Despite dominating possession Vale were unable to find an equaliser, resulting in a defeat for Askey's side in the league, for the first time in over 8 months.
Vale return to action on Tuesday night in the EFL Trophy away to Wigan Athletic.

“Frustrating sums it up. We had a lot of the ball but only really created a couple of chances. You could say the same for them, they had one breakaway where Scott (Brown) made a good save. But it looked the only way anybody was going to score was a penalty.
“But we have to be better. We are not creating enough chances.”
“They sat off us, it was like attack v defence for most of the game but it has worked for them. We have to be a bit more creative, we have to work harder with the runs."
