5. Lynden Gooch - 6
Not a great deal of opportunity to break forward but got the job done, always there to support the defence. Very steady out of position, again. 6 Photo: Frank Reid
6. Corry Evans - 8
The best player on the pitch by a distance. An excellent assist for Broadhead’s opener and regularly swept up when Morecambe tried to break. Composed throughout. 8 Photo: JPI Media
7. Elliot Embleton - 6
A little loose in possession for much of the first half but improved significantly after the break and linked up play nicely. 6 Photo: JPI Media
8. Patrick Roberts - 7
Struggled to get into the game in the first half but was a constant threat through the second, driving into some dangerous areas on the break and going close to a goal. 7 Photo: FRANK REID PHOTOGRAPHER 2022
