Leamington made in four straight wins, to eliminate Strathroy four games to one in their opening round Greater Ontario Junior Hockey League series.
The top-seeded Flyers got their game-winner from Thomas Michaud at 9:57 of overtime.
Dylan Weston also scored for the Flyers at 7:36 of the second period, only to have Cody Clerc tie it for the Rockets just 38 seconds later.
Also Thursday night, Komoka dropped Chatham 6-1 to take that series in five games, to advance to meet the Flyers in round two.
The other division series will see LaSalle battle London.
