Leicester Riders will play Championship leaders Newcastle Eagles in the BBL Trophy final after victory over London Lions in the semi-final second leg.
Leicester went into Sunday's return fixture with a 17-point advantage following their first-leg home win.
Riders' Tyler Bernardini top-scored with 24 points to help book their place in the decider on 22 March at Glasgow's Emirates Arena.
Newcastle eased past Plymouth Raiders with a 52-point aggregate win.
Eagles' victory earlier this month keeps their hopes of winning all four pieces of BBL silverware alive.
Riders coach Rob Paternosto was pleased with his side's focus in the second-leg after taking control of the tie at home.
"With a 17-point lead, psychologically, things can go a couple of ways," he said. "But at no time did I see any complacency.
"From the moment we stepped on the floor, our guys were ready to roll. The first half was important and Tyler Bernardini's shooting was big for us.
"To go in at half-time with the lead - and the aggregate lead as well - put us in a good position."
