Diaz has collected three assists in four appearances for the Flames during exhibition play. Diaz, who signed a professional tryout offer with the Flames prior to camp, has turned heads with his offensive production thus far in camp, putting himself in the conversation for a 23-man roster spot. The 28-year-old bounced between three different organizations last season, but has shown some offensive upside at times during his career. If he ends up making the roster, Diaz could be utilized as a third-pairing player.
