The Adelaide Lightning will count the cost of their most dominant performance this WNBL season, after star import Serena Sundell went down with a suspected knee injury.

Sundell fell to the floor clutching her left knee in the last quarter of Adelaide’s 88-71 win over Sydney on Sunday, after a bump with Flames guard Mikhaela Cann.

The Dallas Wings guard was able to hop off the South Australia State Basketball Centre court, albeit with a grimace, with a season-high tally of 20 points.

Sania Feagin came close to securing back-to-back double-doubles (18 points, nine rebounds), while Dallas Loughridge (14 points, six assists) also impressed.

Victory gave Adelaide (2-2) a second consecutive win, and the result even surprised coach Kerryn Mitchell.

“We feel like we’re starting to find our rhythm as a group. The ball’s moving and we’re finding each other,” she said. 

“We had 16 offensive rebounds in a half. That’s not OK. Obviously, we need to do more work on that.”

Asked about Sundell’s injury, Mitchell said: “I haven’t had a conversation with Serena or the medical staff. But we have some great medical staff. I trust them.”

The Flames produced a convincing offensive performance against the Capitals on Thursday but played well below that level against Adelaide, scoring just seven from 27 three-point attempts and missing another 25 two-point chances.

Go-to scorers Lauren Nicholson (14 points and three steals) and Shaneice Swain (16 points, five steals) shone, while Lara McSpadden (11 points) also showed flashes of her physicality.

Sydney slumps to 2-4, having just snapped a three-game losing streak earlier in the week.

“The positives for the game were for the other team,” coach Guy Molloy said. 

“You can certainly learn a bit from it, but I can’t say that it makes life enjoyable for the next few days.

“We defended, about as bad as I can think for the first four or five minutes, and got into a hole early. The shooting was pretty horrible.”

Both teams started exchanging baskets before Feagin and Loughridge stepped up to create a 10-point quarter-time buffer. 

Sundell helped continue the Lightning’s momentum into the second quarter as they extended the lead to 16 points, which Sydney couldn’t pin back.

Down 46-33 at halftime, the Flames came out energised with McSpadden leading the resurgence before a flurry of turnovers allowed Adelaide to manufacture a 31-point three-quarter time lead. 

After Sundell went down, the Lightning took their foot off the throttle, and the Flames clawed back the deficit.Â
