O’Reilly beat Mongalia’s Shinebayor Narmandakh 30-27 across the board and Gardiner claimed the first two rounds to oust Viktor Vychryst of the Ukraine 29-28 on all three cards
The top five middleweight in Baku qualify for Rio. Super-heavyweights must win gold as there is just one Olympic places in the 91kg+ class.
O’Reilly will now meet Azerbaijan’s Kamran Shakhsuvarly in the quarter-finals on Thursday. Gardiner is in against Moldova’s Alexei Zavatin in the semi-finals on Friday.
A win for O’Reilly will see him join Katie Taylor, Paddy Barnes, Brendan Irvine, Michael Conlan, David Oliver Joyce, Steven Donnelly and Joe Ward on the plane to the 31st Olympiad.
Two wins for Gardiner will suffice.
“Michael and Dean were top class today and they will take a lot of confidence from their performances going into their next bouts,” said Irish team manager Joe Hennigan.
