Sportsnet’s Elliotte Friedman reported the transactions Thursday.
The 25-year-old Slovakian has spent the past two years with the Maple Leafs after being acquired in a trade with the Edmonton Oilers for forward Brad Ross and a fourth-round pick in June 2015. Marincin had one goal, six assists in 25 regular-season games a season ago and suited up for all six of Toronto’s playoff contests.
Pickard, 25, was selected by Vegas in June’s expansion draft off the Colorado Avalanche roster. The Golden Knights claimed goalie Malcolm Subban from the Boston Bruins earlier this week as support for starter Marc-Andre Fleury which left Pickard expendable. The 2010 second-round selection of the Avalanche made 50 appearances in 2016-17, posting a 15-31-2 record, 2.98 goals-against average, .904 save percentage and two shutouts.
