Plymouth beat Leicester 83-64 to become the first team through to this year's BBL Trophy final, where they will play Sheffield Sharks or Newcastle Eagles. It will be their first major final since joining the BBL three seasons ago, and it never looked in doubt.
A 27-16 first-quarter advantage set the tone, and they consolidated that as they outscored the Riders 25-16 in the third quarter.
The Eagles' long unbeaten run ended as they lost 77-73 to the Scottish Rocks.
Milton Keynes romped to victory at Bletchley as they crushed London United 107-64.
Fierce attacking and tight defending helped them to a 19-8 first-quarter lead.
Tarick Johnson and Marlin Capers regained some ground for London in the second period, but from 44-23 the Lions hit three consecutive threes to lead 53-25 at half time.
Every Lions player got on the score sheet, Tony Windless top-scoring with 29 points.
