Sanchez started his British racing career with Glasgow Tigersin 1999. He quickly impressed and spent a further two seasons with the Scottish club before moving to England where he rode for Cornish side, Trelawny Tigers. He was part of their side that won the Premier Trophy in 2002. After moving to Hull Vikings he was part of the side that won the league and cup double in his first season in 2004. When Hull folded after the 2005 season, his contract was bought by Sheffield Tigers and he rode for the Yorkshire outfit in 2006. In 2007 he joined the newly reformed Birmingham Brummies, who ride at the Perry BarrGreyhound racing track, on loan from Sheffield Tigers. However, he had to have his spleen removed after rupturing it in a track crash. It ended his season and for a time there was uncertainty over his ability to start the 2008 season. In the end he made a full recovery and signed for Stoke Potters. His confidence around their home track at the Loomer Road Stadium suffered and in early June he moved to Scunthorpe Scorpions. In 2009 Sanchez was signed by the Kings Lynn Stars after the Stars learned that John Oliver would not be returning to the UK from Australia for the 2009 season. Sanchez proved an inspired signing, helping the Stars secure the Premier League Championship and Premier Trophy.
