SUNRISE, Fla. (AP) — The Florida Panthers entrusted their season to a rookie goalie making his playoff debut. Spencer Knight delivered. The 20-year-old Knight stopped 36 shots, Mackenzie Weegar had a goal and an assist, and the Panthers defeated the Tampa Bay Lightning 4-1 in Game 5 of their Central Division playoff series. The Lightning still lead the best-of-seven series 3-2 and host Game 6 on Wednesday night. But Knight — the third different goalie to start for Florida in this series — stymied the reigning Stanley Cup champions.
