Holmberg scored the game-winning goal and added an assist in Monday's 4-1 win over the Flyers.
The 27-year-old gave the Lightning a 2-0 lead just 17 seconds into the second period, ripping a shot from the faceoff circle past Dan Vladar to convert a 3-on-1 break. The points were Holmberg's first of the season in three games, as the bottom-six forward looks to match or improve on a career-best 2025-26 campaign in which he managed 11 goals and 22 points in 70 regular-season contests.
