With their All-Star forward sidelined, the Chicago Sky are having difficulty maintaining the form that put them atop the Eastern Conference after six games.
A visit from the WNBA's only winless road team could help them get back on track.
The short-handed Sky might again have to go without Elena Delle Donne on Sunday when they seek only their second victory in June while trying to deal the Tulsa Shock their seventh straight road defeat.
Coming off a 2013 in which she was an All-Star and won Rookie of the Year honors, Delle Donne put up 21 or more points in five of the first six games this season while guiding Chicago (6-6) to an East-best 5-1 start.
The conference player of the month for May was averaging an East-leading 22.3 points before a flare-up of Lyme disease forced her out of the lineup. The Sky have dropped three of four without her and fell to 1-5 in June with Friday's 83-75 home loss to Indiana.
Chicago is also missing 2013 All-Star center Sylvia Fowles, who is hoping to return near the end of the month following offseason hip surgery. Without two of their top rebounders, the Sky were beaten 36-26 on the boards by the Fever while managing only three offensive rebounds.
"We didn't deserve to win, so we didn't," coach Pokey Chatman said. "We can't beat anybody with three offensive rebounds."
That could continue to be a problem against Tulsa, which is second in the WNBA with a plus-2.64 rebounding margin. The Shock (4-7) outrebounded Phoenix 42-29 Friday, but shot 6 for 24 from the field in the fourth quarter of a 91-80 loss.
Glory Johnson had 20 points and 11 rebounds and Courtney Paris scored 15 with 15 boards. Paris leads the league with 11.0 rebounds per game, while Johnson is sixth at 9.0.
Johnson had a combined 29 points and 23 boards to help Tulsa earn a split of last season's series, though Chicago has won the last four meetings at home by an average of 17.8 points.
The Shock haven't won on the road since Sept. 8 at San Antonio after their rally from a 15-point deficit fell short Friday. They're 0-2 on a four-game trip following a season-best four-game winning streak.
Skylar Diggins, fifth in the league at 18.3 points per game, looks to bounce back after she was held to 12 on 4-of-15 shooting in Phoenix. She totaled 13 points while missing 12 of 16 shots against the Sky as a rookie last season.
Epiphanny Prince led Chicago with 19 points in a 92-71 win in the most recent meeting at All-State Arena on June 2, 2013. The All-Star guard, who scored 18 on Friday, is averaging 20.8 points in her last four games overall.
It's uncertain whether Tulsa guard Riquna Williams will play after missing three of the past four games due to a knee injury.
