2011-12: Patrick Sanvido skated for the Guelph Junior Storm midget minor AAA team in Ontario. He scored 6 goals with 27 assists and 68 penalty minutes in 56 games. Sanvido was selected by Windsor in the second round (41st overall) in the 2012 OHL Priority Draft.
2012-13: Sanvido played in 60 of 69 games for the Windsor Spitfires in his first OHL season. He had 6 assists and was -16 with 40 penalty minutes. The Spitfires missed the playoffs, finishing last in the West Division.
2013-14: Sanvido returned to Windsor for his second OHL season. He scored 1 goal with 7 assists and was -21 with 82 penalty minutes in 64 regular season games. Windsor finished second in the West Division and lost to London in a first round playoff series. Sanvido was -2 with no points and 7 penalty minutes in four playoff games. He was ranked 140th amongst North American skaters in the Central Scouting final rankings and was selected by Dallas in the seventh round (195th overall) in the 2014 NHL Draft.
Sanvido is a large, old school defenseman almost solely focused on defending in his own zone with little offense to his game. He is an average skater, maybe above the mark when size is considered and has limited puck skills. His defensive play is raw and he is behind the play at times. His hockey sense and skill set may be too limited for him to become an NHL regular unless he has a niche. He is still learning how to apply his body, physicality, and strength. Sanvido is a willing combatant when it comes to dropping the gloves.
Sanvido skated for the Stars in the 2014 Traverse City rookie tournament and attended the Dallas training camp before being returned to Windsor for the 2014-15 season. In his third season with the Spitfires he is an assistant captain. As with any seventh round pick his prospects of playing in the NHL one day are limited. Sanvido's willingness to come to the aid of teammates offers some potential as an enforcer, lower pairing defenseman.
