LIGHTNING captain Nicole Seekamp today broke a long-standing WNBL assists record when she dished 20 to grateful teammates as Adelaide swamped league-leader Southside 104-93.

Bendigo's super guard Kristi Harrower took over the record in 2014 with 19, breaking the 21-year-old benchmark of 18 set by Sydney guard Michele Landon in 1993.

Adelaide's club record of 14 set by Vicky Daldy in 1989 - and matched by her again in 1992 - also was shattered as Seekamp opened Lightning's big win with eight assists in the first quarter, as many as any other player would tally for the contest.

It meant she had a hand in all but one of the team's 10 field goal attempts as she also scored, Adelaide seeing its early 13-8 lead overtaken courtesy of some slick shooting by Leilani Mitchell.

But Lightning completely controlled the second period, Lauren Nicholson (24 points at 67 percent, 4-of-7 threes, five rebounds, four assists, two steals) with eight points on 3-of-3 shooting, Brianna Turner (25 points at 56 percent, nine rebounds, two assists, a steal and two blocks) with six points, Seekamp scoring eight on 3-of-3, and Chelsea Brook six points on 3-of-4 as Southside had no answers.

Kathryn Westbeld (22-point WNBL career-high, at 67 percent) also was at her most cool as Adelaide broke away from 45-39 to 54-39 and was out as far as 57-41.

For the Flyers, Mercedes Russell (28 points at 71 percent, 10 rebounds, two assists, three steals) fought virtually a lone hand offensively, with 18 at the half, Adelaide ahead 60-48 and shooting at a remarkable 64 percent to Southside's tidy 51.

Jenna O'Hea collected two quick fouls early in the game and never was able to be a factor but Sara Blicavs (18 points, seven rebounds) cut loose in the third with three 3-pointers to bring the Flyers rallying back.

Westbeld was again terrific with a nine-point period and Steph Talbot (seven points, seven reounds, eight assists) accommodating as Adelaide initially found issues against the Flyers' zone.

Louella Tomlinson came in for the final two minutes and produced a quick six-point return to keep Southside alive, down 75-86 with a quarter left at Titanium Security Arena.

Blicavs stuck her fourth three and with Russell menacing, Southside closed to 83-88 before a 12-2 Lightning run, featuring some exceptional teamwork, swept them to 100-85.

Swishing her fourth 3-pointer, Mitchell reminded Adelaide there was still a win to be consolidated but Lightning did just that, shooting at 55 percent to Southside's excellent 47 in one of the highest-quality WNBL games this season.
