Defending champions Manchester Mystics kept their playoff title defence alive as they saw off CoLA Southwark Pride 53-34.
Masie Keyes (22pts, 8ast, 6stl) came through big for the Mystics in a low-scoring affair, with Irene Oboavwoduo (10pts, 17reb) also adding a valuable double-double.
CoLA struggled for offence throughout, with Dajah Chapman (8pts) coming out as their top scorer.
Richmond booked a spot in tomorrow's final with a narrow 78-71 win over Ipswich.
After a relatively even first half, the Knights used a 15-3 third quarter run to create the advantage needed for victory, though Ipswich did fight back to within three midway through the fourth.
Richmond were led by Precious Godwin (26pts), Madi Warren (20pts) and Chloe Vella (9pts, 20reb), whilst Ipswich got 25 points from Cerys Leach and a 14 point, 25 rebound double-double from Deanna Carrington.
The weekend got off to a stunning start in the back hall as Manchester just pipped London Elite 80-76.
With neither team leading by more than four points throughout the final quarter, it was neck-and-neck the whole way before Manchester eventually iced the game from the line.
David Akhidime (27pts, 15reb) was massive for Magic in the win along with team mate Ege Cakmakkaya (16pts, 9reb), with Kaya Birsen (23pts, 5reb, 5ast, 9stl) leading the way for London.
Thirty two points from Nojus Zajankauskas pushed Baltic Stars into tomorrow's final as the Londoners beat Manchester Giants 93-69.
Zajankauskas was the standout as he helped his side pull away further the longer the contest went on, with Nathaniel Kajus Sowah adding a 16-point, 12-rebound double-double off the bench.
Harry Sheehan top scored for the Giants with 19 points.
Sussex Storm came through a nervous semi-final with London Lions, emerging as 67-62 victors.
Storm has led by double digits early in the fourth before the Lions roared back, but two points was as close as they'd come before the final buzzer.
Rafi Jalloh (21pts, 5reb) played well for Sussex, cancelling out 21 points from London's Khyle Capanzana.
Manchester's title defence continues, as does their undefeated season, after they beat Sheffield Hatters 87-58.
The Mystics led from tip to buzzer thanks in part to Mojan Malek, who dropped a game-high 27 points as Anya Williams added a 14-point, 12-rebound double-double.
Sheffield were led in defeat by Millie Lowe (16pts, 15reb) and Ophelia Larder-Lee (12pts, 14reb).

Ipswich can still add playoff glory to their U18 National Cup triumph after they beat Manchester Mystics 88-80.
With Mystics holding a slender lead for the majority of the first half, Ipswich came on strong after the break thanks to an impressive outing from Yazmin Edwards.
The young guard had just two points at the main change but closed with 20 plus 11 boards, doing more than enough to power her side's late surge.
Manchester's resistance was led by Josephine Vourliotis, who splashed six triples on her way to a game-high 26 points.
CoLA's aim of winning a sixth straight U18 title is still alive after a trademark 61-39 win over City of Birmingham Rockets.
Coach Gibbons' side held the Rockets to just 23% shooting from the floor, claiming the low-scoring contest off the back of 12 points and seven boards from young forward Felicia Jacobs-Abiola.
Sarah Elfrey (14pts) and Danielle Wallis (12pts) were the only CoB players to make it to double-digits scoring, whilst all but one of CoLA's 12 scored at least two points.
London Warriors erased a 15 point second quarter deficit for a 73-70 comeback win against London Baltic Stars.
Stars raced out of the blocks with a 24-14 opening quarter, growing their lead further in the second frame before the Warriors set about getting back into the game.
It took until the final quarter for the Warriors to move ahead, but once they did it stayed that way.
Jeremi Dutka played the full 40 for Warriors in the win, dropping 25 points. Oskaras Visockas had a massive 26 point, 24 rebounds double-double for the Stars, but it wouldn't be enough.
Another final for Nick Drane and @IpswichBball

In the final game of the day on Court 1, hometown Magic put on a show for the Manchester faithful as they downed Haringey Hawks 78-59.
Joe Buchanan (26pts, 5reb) got the job done on the scoreboard and team mate Shaquille Furlonge (16pts, 18reb) controlled the glass as Manchester moved into tomorrow's final at a canter.
Chudi Dioramma (22pts, 16reb) played a solid game for the Hawks, who must now settle for either third or fourth place.
London Elite just outlasted cross-town rivals CoLA as they hung on for a 59-56 W.
Elite led for most of the semi-final, including the entirity of the final quarter, though CoLA pulled to within a basket more than once over the last minute.
The National Cup winners would keep a cool head to see the game out though, boosted by 16 points and nine boards from Hunter Kelleher.
Kyle Espitu had a team-high 16 points plus seven assists for CoLA.
Richmond Knight are into U14 Girls final once again as they easily dispatched Milton Keynes Breakers 113-25.
The victory sets up a repeat of last season's final when the Knights were beaten 58-51 by Manchester Mystics, adding an extra layer to tomorrow's already compelling contest.
Precious Godwin led all scorers for Richmond with 16 points, Faith Deakin, Luna Etienne and Chantelle Okoli all had four points for the Breakers.
