No Breanna Stewart, no problem.

The Liberty were without their two-time MVP on Saturday but still put away the Sky for a second straight game, beating Chicago, 81-67, at Wintrust Arena to move their league-best record to 20-4 behind Sabrina Ionescu’s 28 points on 9-for-21 shooting.

“We had to do a little bit more, obviously, with some starters out,” Ionescu said. “But we believe in every single player on this team and their capability and understanding what they’re able to come in and help us achieve. Hats off to them.”

In addition to Ionescu’s scoring, contributions from Leonie Fiebich and Ivana Dojkic — who combined for 25 points — helped the Liberty make up for Stewart’s absence.

Down low, Fiebich and Jonquel Jones — who finished with 14 points, nine rebounds and seven assists — served to limit Chicago’s twin towers of Angel Reese and Kamilla Cardoso in the paint enough for the Liberty to get by in this survive-and-advance match.

Reese, who took a record 15-game double-double streak into Saturday, finished two points short of extending it and received a technical foul in the fourth quarter thanks to her reaction to a fifth personal foul.

Just a couple of days after it took the Liberty until late in the game to pull away from Chicago in Brooklyn, a 15-0 run into halftime helped the Liberty put their foot down earlier.

After a slow start for Ionescu, she got going late in the second quarter to help spark a run that left Chicago in the dust, assisting a Dojkic 3 and a Jones layup while hitting a pair of free throws to finish the half.

Suddenly, the Liberty — who had not led since it was 3-2 — were up by nine heading into the half, and their best player was cooking.

“It’s a long game and we started the game, I think, taking some quick shots, some rough shots. As soon as we slow the ball down, we’re able to drive and kick, we’re able to get into the paint,” Ionescu said. “We established JJ off pick and rolls down low. That just opened up the floor for us, obviously in transition, as well.”

Dojkic had a simpler explanation.

“I think that when we play for each other,” she said, “we’re really unbeatable.

“When we share the ball, when we always try to find each other in the best positions, we are very, very effective.”

A brief scare came when Marina Mabrey hit a pair of 3-pointers to bring the Sky within seven going into the fourth quarter.

But the Liberty kept them at arm’s length for the entirety of the fourth, as Chicago never reestablished its early edge down low and couldn’t put together a run.

Consecutive buckets from Chennedy Carter got the Sky within eight with 3:27 to go.

But a free throw-line jumper from Ionescu followed by Sky coach Teresa Weatherspoon taking a technical foul got the lead back to double digits with 90 seconds left — more than enough to hang on.

A deep 3-pointer from Ionescu proved to be the dagger.

Aside from moving to 20-4 on the season, though, the best news of the day for the Liberty was that Stewart’s injury does not appear to be a long-term concern.

“Stewie probably could have went today but it’s the smartest thing to give her a rest,” coach Sandy Brondello said. “Just taking time where we can. It’s a big game for us but we still have to think big picture, be smart about our players’ health as much as we can.”

Brondello cast the decision to sit the superstar forward, whose 19.3 points per game lead the Liberty, more in terms of load management than any cause for concern.

Kennedy Burke started in Stewart’s place, finishing with seven points.

The Liberty were also missing Betnijah Laney-Hamilton with a right knee injury for a third straight game.

“Just a little injury,” Brondello said of Stewart. “Give her the rest today. She’ll hopefully play next game.”
