Luukkonen made 26 saves in Saturday's 8-2 win over the Rangers.
The Sabres chased Igor Shesterkin from the game with a five-goal first period, and while Luukkonen's shutout bid ended early in the second on a Chris Kreider power-play tally, his win was never in jeopardy. The 25-year-old netminder has won four of his last five starts, and since the beginning of January, he's gone 8-4-1 with a 3.08 GAA and an .890 save percentage.
