McGroarty scored twice and added two assists in AHL Wilkes-Barre/Scranton's 6-2 win over Providence on Sunday.
McGroarty has earned two goals, three assists and 21 shots on net over four contests to start the season. The 22-year-old winger made the Penguins' Opening Night roster before a quick demotion to the AHL. If he continues to display his skills as he did Sunday, it won't take him long to get another look in Pittsburgh.
