Career
Martyn began his youth career with Kingsmead Boys Club, before then moving on to Valspar Boys Club. Campbell then made the move to Tarff Rovers in the South of Scotland League before signing for Junior side Kello Rovers. lieutenant was at Kello that Campbell first caught the eye of Irvine Meadow manager Robert Riley, who then signed Campbell and then brought him to with him in 2005 after Riley was appointed Robert Connor"s new assistant manager at the club
In 2005, Campbell followed his former manager, Robert Riley, to Somerset Park and in his first season he made 23 appearances in all competitions.
In his second season, Campbell was a first time regular making another 21 appearances. In Campbell"s third season he only featured in 12 games, due to injury, which unfortunately was not the last time he had missed large parts of a campaign due to injury.
In January 2009, Campbell was struck by Kilmarnock"s David Fernandez in an Ayrshire derby that was being shown on Sky Sports. Campbell was instrumental to the clubs success and played in all of the clubs play-off games as the Honest Men secured promotion back to the First Division.
The following season, Ayr finished bottom and Campbell played in 28 matches, and Campbell was initially released at the end of the season, before being offered a trial during pre-season by then manager, Brian Reid, who then offered him a new deal, which he signed.
Campbell was once again instrumental to the club"s success throughout the 2010-2011 campaign, playing 36 times and scoring another goal, this time in the Challenge Cup against Cowdenbeath, as well as featuring in Ayr"s famous victory over Hibernian in the Scottish Cup and in all of the club"s play-off games, which saw Ayr promoted back to the First Division. The 2011-2012 season was more difficult for Campbell as he only featured 13 times, missing most of Ayr"s impressive cup runs. Despite a disappointing season before, new manager Mark Roberts kept Campbell at the club on a pay-as-you-play basis and Campbell only went on to play in four matches.
The next season saw Campbell"s name return to the team sheets more regularly, featuring a total of 21 times.
The 2014-2015 season was a disastrous campaign for Ayr, however towards the end of the year, intended on honouring Campbell with a testimonial.
