Bruins storm back to tie series
Gaborik redirected Anze Kopitar's shot past Jonas Hiller for the winner.
The Ducks appeared poised for a win after 43-year-old Teemu Selanne beat Jonathan Quick between the pads for a go-ahead goal with 11:52 to play in regulation.
But the Kings pulled Quick for a sixth attacker with 1:22 left. Mike Richards took a shot from along the left boards, and Gaborik wristed the rebound past Hiller.
Bruins stun Montreal
The host Boston Bruins rallied from two goals down to avoid another two-game deficit against the archrival Montreal Canadiens.
Reilly Smith scored the go-ahead goal with 3 minutes, 32 seconds left and Boston scored four times in eight minutes to beat the Canadiens, 5-3, on Saturday and even the Eastern Conference semifinals at one game apiece.
"It was a fun last part of the third period," said Torey Krug, who set up Smith's goal. "We're very excited with how things turned out, but we've got to move along from it pretty soon."
Games 3 and 4 are on Tuesday and Thursday in Montreal, where in 2011 Boston won twice in its first-round series after losing the first two at home. The Bruins won the series in seven games and went on to win their first Stanley Cup title in 39 years.
Last year, the Bruins trailed Toronto by three goals with 11 minutes left in Game 7 of their first-round series before winning in overtime.
