Given how tight the standings are at the moment, any game the Pittsburgh Penguins play this week is a potential playoff preview. On Sunday afternoon, they passed their first test of the week with a 1-0 shutout victory over the Boston Bruins at PPG Paints Arena to move into first place in the Eastern Division. Jake Guentzel struck early in the third period for the game’s lone goal and Tristan Jarry kept the Bruins at bay all game long for his first shutout of the season. [Pensburgh]
