Question: What is the nickname of the team that Greaves debuted against in the 2008-09 season? Passage:He was released after a season at Burton and joined fellow Conference Premier side York City on 14 May 2008. He was appointed as club captain for the 200809 season. His debut came in a 10 victory against Crawley Town and scored the only goal in the subsequent game against Wrexham. Greaves suffered from foodborne illness in September, which resulted in him losing 9pounds, and missing York's match against Kidderminster Harriers. He scored a 94th-minute equaliser against Mansfield in the Conference League Cup third round on 4 November, which York eventually won 42 on a penalty shoot-out following a 11 draw after extra time. He started in the 2009 FA Trophy Final at Wembley Stadium on 9 May 2009, which York lost 20 to Stevenage Borough. Following the end of the season, during which he made 46 appearances and scored four goals, he entered negotiations with York over a new contract.
