Lehner stopped 29 shots in regulation and overtime and both shootout attempts he faced in Sunday's 4-3 win over the Islanders.
The 30-year-old won his fifth straight decision, but he needed Shea Theodore to score in the final minute of the third period to avoid his first loss since Dec. 1. Despite his recent success, Lehner hasn't been sharp this season and he now sports a 3.03 GAA and .905 save percentage through 24 appearances.
