While the home defence definitely locked down Good Angels Kosice far better in the second quarter to hold them to just 14 points in the period, it was to the detriment of their offence.
Despite doing a good job defensively, TTT Riga could didn't even break double figures during the next ten minutes which meant they headed to the locker rooms in trouble and trailing 43-28.
They fared much better after the break and when a Kim Butler basket made it a five point game, the home supporters might had reason to cheer - but only temporarily.
Kosice began to ease away again and with Houston in irresistible form, they edged away again and eventually ran out as easy winners.
Dupree had a double double of 17 points and 10 rebounds for the winning team while Zirkova had 16 points and 6 assists.
Shavonte Zellous and Kristine Karklina both registered 17 points for TTT Riga who are still searching for their first win in Group A.
