PITTSBURGH (AP) – Mike Sullivan is sticking around to see if he can add to his Stanley Cup collection with the Pittsburgh Penguins. The club has signed Sullivan to a four-year contract extension that runs through the 2023-24 season. The terms of the new deal will kick in when Sullivan’s current contract expires at the end of the upcoming season. Sullivan became the first coach in nearly two decades to win consecutive Stanley Cups when he guided Pittsburgh to championships in 2016 and 2017.
