On June 30, 2006, Denis was traded to the Tampa Bay Lightning and Leclaire was promoted to starting goalie. However, during the season, Leclaire suffered from a leg injury and backup goaltender Fredrik Norrena took over and eventually played 55 games out of 82. In 2007–08, Leclaire had an outstanding season and regained the number one job. He set new team records with nine shutouts (second in the league only to Henrik Lundqvist), ranked second in the NHL in goals against average, and third in save percentage. Leclaire finished second in fan voting among Western Conference goaltenders for the 56th NHL All-Star Game, but was not named to the final team.
