Buffalo Sabres hold a 3-2 series lead over the Boston Bruins in their Eastern Conference first-round Stanley Cup playoff matchup, driving trader consensus to an implied 79% probability for Sabres to advance despite Boston's dramatic 2-1 overtime victory in Game 5 on April 28, where David Pastrnak scored the winner and goaltender Jeremy Swayman made 24 saves. Sabres dominated Game 4 with a 6-1 rout fueled by Alex Tuch and Cole Doan's multi-point efforts, showcasing superior recent form and power play efficiency, though rookie center Noah Ostlund exited Game 5 with a lower-body injury that clouds their depth up the middle. Bruins forward Viktor Arvidsson remains sidelined by an upper-body issue, weakening their forward group, while Buffalo's Rasmus Dahlin anchors a stout defense ahead of critical Game 6 at TD Garden on May 1. Historical head-to-head favors Boston 6-2 in prior playoff series, but current momentum and home-ice advantage tilt odds heavily toward the Sabres closing out.
