Born in Ondarroa, Biscay, Martínez joined Real Sociedad's youth ranks from local Aurrerá de Ondarroa. He made his senior debuts in the 2009–10 season, helping the B-team promote from the fourth division after one year out by contributing with 23 games and one goal.
On 27 August 2011 Martínez made his first-team – and La Liga – debut with the Basque, playing the full 90 minutes in a 2–1 away win against Sporting de Gijón. On 2 October he scored his first league goal, netting from inside his own half in an eventual 1–2 home loss against Athletic Bilbao, in a derby.
Martínez made his debuts for the Spanish under-21 team in 2011. In the following year, he was picked by manager Luis Milla for his squad that appeared in the 2012 Summer Olympics in London: in the first game against Japan, he was sent off late into the first half for bringing down Kensuke Nagai thus denying a clear goalscoring opportunity, in an eventual 0–1 loss.
