While Sorokin backstopped Tuesday's win, Zach Parise and Josh Bailey powered the offense with a pair of goals apiece.
Parise owned the first period on Tuesday night, netting a power-play goal and a shorthanded goal in the opening 20. Tuesday marked the first time in Parise's 1,132-game career that he'd scored on the power play and down a man in the same game.
Both goals came in similar fashion, with Parise burying a couple of cross-ice feeds off the rush. Mathew Barzal found Parise at the right faceoff dot and the 37-year-old roofed a shot high short side on Casey DeSmith at 9:10 to tie the score 1-1. Less than three minutes later, JG Pageau led a shorthanded rush up the ice before feeding Parise for a backdoor tap in.
The two-goal game was Parise's second as an Islander - and first since Feb. 22 in Seattle. Per Greg Picker, Parise is the first Islanders player since Frans Nielsen on Feb. 23, 2016 to score a power-play goal and a shorthanded goal in the same game.
Parise nearly had a third goal in the period, but was robbed by DeSmith on a backdoor feed from Barzal with the game tied 0-0. Barzal did some nifty work in the Penguins' zone, curling off Sidney Crosby before feeding Parise.
"You're happy for him because he's plays multiple roles for our team and important ones and you want those guys to get rewarded," Trotz said of Parise. "So he plays the right way. That's to me why he's had success, why he's a good pro and why he's here."
Bailey also had his first two-goal game since March 11, giving the Islanders a 3-1 and 4-3 lead respectively. Bailey was in the right place at the right time in both instances, slapping a Penguins turnover far side on DeSmith at 19:22 of the first period for his first. The winger was virtually untouched on his second goal, corralling another turnover before backhanding a shot past DeSmith to break a then 3-3 tie.
