One month after being mired in ninth place in the Western Conference, just hoping to squeeze into the postseason, the San Jose Sharks have clinched a ninth straight playoff berth and now can push for home-ice advantage in the first round. Logan Couture and Joe Pavelski scored goals 30 seconds apart late in the third period to help the Sharks clinch the playoffs in their final home game of the season with a come-from-behind 3-2 victory over the Dallas Stars on Tuesday night.
