the NAB Young Footballer of the Year which was eventually won by Marco Rojas. Sainsbury was named the Mariners Player of the Year for the 2012–13 season. He was also named in the PFA A-League Team of the Season for 2012–13. After the announcement of the first A-League All Stars match, Sainsbury was considered one of the main contenders for a place in the squad. He did not end up playing in the match due to international selection. Sainsbury scored his first competitive goal for the Mariners on 3 April 2013, in a win over Guizhou Renhe in the 2013 AFC Champions League, his header with under ten minutes remaining proving to be the winner. His first A-League goal for the side came from a corner in a 2–1 win over Perth Glory in December 2013. PEC Zwolle 2013–14 season Sainsbury signed for PEC Zwolle in the Dutch Eredivisie on a two and half year deal in January 2014. Sainsbury was immediately placed in the starting line-up, making his Eredivisie debut on 6 February 2014 in an away game against FC Utrecht. PEC won the game 2–1, but Sainsbury had to be replaced after 72 minutes after falling on a depressed sprinkler, hurting his knee in the process. It was discovered after the match that Sainsbury had fractured his kneecap on the sprinkler, an injury that would end up ruling him out for the remainder of the season. Fellow Australians Tommy Oar and Adam Sarota played in the match for Utrecht. His club PEC did end the season on a high note when they won their first major trophy in the club's history by defeating league champions Ajax 5–1 in the 2014 KNVB Cup Final, also securing European football for the first time. 2014–15 season Recovered from his knee injury, Sainsbury was reinstated in PEC's starting lineup for their first game of the season - the 2014 Dutch Supercup. The game was played against the same team that PEC defeated to win the KNVB Cup, 2013–14 league champions Ajax. Sainsbury was part of a defence that kept a clean sheet in a 1–0 win, securing PEC's second major trophy in the club's history in the space of 4 months. Sainsbury retained his place in the starting line-up for the first league game, at home against FC Utrecht. Lightning would strike again, as Sainsbury was subbed off with an ankle injury
