The Ads, which came on strong in the second half to earn their twelfth consecutive spot in the second season, failed to hold serve; dropping a pair of games to the Toronto Marlies at the BMO Harris Bradley Center last weekend.
They will have to win three in a row on road ice in Ontario.
Game Three is on Thursday night, May 1, at Ricoh Coliseum. Puck drop is at 6 p.m. CDT.
Major Goolsby's Sports Bar, 340 West Kilbourn, in downtown Milwaukee will broadcast the game on their 54 HDTVs at a viewing party for Admirals fans.
There will be food and beverage specials and raffles.
Prizes at viewing parties during the season have included autographed jerseys and sticks.
