New York Liberty forward Breanna Stewart will be examined by the team's medical staff after suffering an apparent left knee injury in overtime of her team's 76-69 win over the host Phoenix Mercury on Sunday in Game 1 of their WNBA first-round series.
Stewart suffered the injury with 3:01 left in the extra period when she attempted a layup against Phoenix's Satou Sabally and DeWanna Bonner. As Stewart went up, she already appeared to be grimacing, and as she landed on the court, she immediately grabbed at her left knee.
Stewart initially stayed in the game, but Liberty coach Sandy Brondello said that Stewart asked to be subbed out after feeling "discomfort." After Stewart sat on the bench, she looked visibly in pain and had tears in her eyes.
After the game, Brondello didn't provide an update on Stewart, who finished with 18 points.
"We're just hoping that she will be OK," Brondello said.
Stewart missed 13 regular-season games because of a bone bruise on her right knee, and in March, she had a scope on her right knee.
Despite Stewart's exit, New York took Game 1 and stole home court from the Mercury.
Natasha Cloud, who played in Phoenix last season, made back-to-back layups to give the Liberty a two-point lead with 4:17 left in the fourth quarter. Kahleah Copper answered with two free throws and, after a turnover by Sabrina Ionescu, Alyssa Thomas made a no-look pass to Copper for a wide-open layup that gave the Mercury a 65-63 lead with 1:44 remaining.
Stewart then made a tough basket in the lane 13 seconds later that eventually forced overtime.
"We looked around and realized we kind of have been in that position before," Ionescu said. "Understanding how important overtime is and knowing we had another gear to get to. I'm proud of the way we stuck together, we weathered the runs they went on, and ultimately found a way to win."
Cloud hit a 3-pointer to open overtime and spark an 8-0 run that made it 73-65 with 1:51 left. Phoenix trimmed its deficit to four, but Leonie Fiebich, who finished with 10 points, hit a huge 3-pointer to seal the win.
"She had missed some early on, but I knew she was going to hit the biggest one of the night," Ionescu said about Fiebich's shot. "It's what she does ... she's one of the best 3-point shooters in the world."
The Liberty, who averaged 13.8 turnovers in the regular season, finished with 20 turnovers -- one shy of their season high -- which included 14 after halftime.
Brondello said she knew that this series against the Mercury would be a slug fest, and she pointed to her team's defense as the Liberty's highlight Sunday.
The Mercury made 25 of 77 (33%) from the field and shot 23% (6 of 26) from 3-point range.
The Liberty return home to New York, where they can sweep the series in Game 2 and advance to the semifinals for the second season in a row.
Despite Stewart's uncertain availability, the Liberty do not want to squander a chance to close out this series quickly.
"We have the advantage," Brondello said. "We won on their home court and now the advantage is for us to take care of it. This is an experienced team, and we've been here before. We know what our goal is, and we want to keep playing."
