The team got swept in the Western Conference Final Sunday in Chicago.
The Blackhawks now go on to compete for the Stanley Cup, while the Sharks took a long plane ride home to the South Bay.
"I'm not going to criticize the effort," San Jose defenseman Dan Boyle said. "We didn't find a way to get it through and I'm not really sure why that is."
The Blackhawks can thank a big goal by Big Buff for their big win.
Dustin Byfuglien scored his third go-ahead goal, converting on a third-period power play. The 257-pound Byfuglien was parked in front of the net with 7 seconds left on the power play. He took a nice pass from Patrick Kane and knocked the puck past Evgeni Nabokov to give the Blackhawks a 3-2 lead at 14:05 of the final period.
Kris Versteeg added an empty-net goal with 42 seconds left, and the red-clad fans at the United Center erupted, littering the ice with souvenir towels.
Sunday was another disappointing ending for the Sharks, who won the conference in the regular season by a point over the Blackhawks. They outshot Chicago in three of the four games but couldn't break through, scoring only seven goals in the series.
"There's a level of frustration about the way we approached this whole series," San Joe defenseman Rob Blake told the Associated Press. "We put ourselves in a position to be successful throughout the season and we didn't accomplish what we needed to."
"They seem very destined right now," coach Todd McLellan said of the Blackhawks. "They have a goaltender that's on fire. They're getting scoring not necessarily from their superstars, I mean that with all due respect to the Byfugliens, the Bollands, those type of players.
"They're doing the things they need to do to win."
