Ullmark was the first goalie off the ice at Ottawa's morning skate. The Senators appear to control the first Wild Card position in the Eastern Conference. Still, they will be desperate for a win after losing two straight (0-1-1), turning to Ullmark between the pipes on Thursday against the Tampa Bay Lightning. Ullmark struggled in his most recent outing, allowing four goals on 21 shots (.810 SV%) in a 5-2 loss to the Buffalo Sabres. The 31-year-old netminder has a 2.80 GAA and .907 SV% in 40 games this season (21-14-3). The Senators enter Thursday's contest as +127 home underdogs against a Lightning squad outscoring their opposition by a whopping 25-5 score during a four-game winning streak.
