It was Chicago's Sylvia Fowles, however, who shined when the Eastern Conference rivals met last month.
Pondexter and the Liberty look to avenge June's defeat while Fowles and the Sky try to snap a three-game road losing streak Sunday.
Pondexter, who ranks third in the league with 18.5 points per game, averaged 24.8 on 62.7 percent shooting against Chicago in 2010 as New York (6-5) swept the four-game season series.
The Sky (6-6), though, defeated the Liberty 85-73 on June 17 as Fowles recorded 27 points and 11 rebounds.
"Sylvia is obviously the best center in women's basketball," Liberty coach John Whisenant said of the 6-foot-6 All-Star, who leads the WNBA with 20.9 points per game.
While Fowles' size was too much for New York to handle, Chicago also clamped down defensively on Pondexter, who scored 20 points but was just 4 of 16 from the floor. She did, however, make 12 of 14 free throws.
"Defensively, we did a good job on Cappie early," Sky coach Pokey Chatman said. "It's tough to stop her when she gets to the line and we'll definitely work on that."
Pondexter didn't attempt a free throw Friday but recorded her seventh 20-point effort of the season during a 76-73 win at San Antonio. Since losing four straight June 11-21, New York has gone 4-1.
"We've been struggling off and on," said Pondexter, who had 20 points, nine rebounds and seven assists while going a season-best 4 of 5 from 3-point range. "It just shows how we can play when we play together."
The Sky, meanwhile, recorded their second straight victory Saturday, defeating Atlanta 81-69 despite a quiet offensive performance from Fowles. After scoring a season-best 34 points in Tuesday's 78-65 win over Washington, she had a season-low-tying 10 against the Dream, although she did post 12 boards, five blocks and three steals.
With Fowles taking a smaller role on the offensive end, Epiphanny Prince scored 24 points and Courtney Vandersloot added 16 as Chicago erased a 13-point first-half deficit.
"I just wanted to be aggressive and attack the rim," Prince said. "I didn't think I was doing that well on defense, but I just wanted to be aggressive."
Chicago, which has been outscored by an average of 10.3 points during its three-game road skid, could use another solid performance out of Prince as it tries to get back above .500 for the first time since it was 4-3 on June 23.
