Mohegan — The WNBA standings are a bit wacky after a third of the season because seven teams are under .500 and only five have winning records.

The Connecticut Sun are among those five and while homecourt advantage isn’t the be-all and end-all in the postseason, it’s still preferable to play more of those games in one’s own arena.

The Sun have already clinched one season series against a top five teams and will try to clinch another on Sunday afternoon when they visit the Washington Mystics at Entertainment and Sports Arena (2 p.m., CBS Sports Network).

“There’s a confidence factor that we beat (Washington) the first time,” Sun head coach Curt Miller said after Friday night’s 82-71 win over the Seattle Storm at Mohegan Sun Arena. “Tonight’s win was huge, right? Playing teams in the top five in the league and having a chance to win a series and win that tiebreaker if we need it for playoff seeding is huge.

"So, winning the Seattle series tonight, huge, because they’re going to be a top five team.”

Connecticut (12-4) is second in the overall standings and is 4-2 against the league’s other winning franchises. It has beaten Seattle twice with one game remaining (July 28). It split two games against league-leading Las Vegas Aces (they play the last game of their series at Mohegan Sun Arena on July 17).

The Sun lost their lone matchup against the defending champion Chicago Sky (83-79, June 10). They won their only game against Washington (79-71, May 28).

The Mystics (10-7), however, were shorthanded the first time around against Connecticut because starters Alysha Clark and two-time WNBA MVP Elena Delle Donne didn’t play.

Clark was in health and safety protocols and Delle Donne was given the night off as the team is trying to manage her minutes during the first half of the season after not playing the previous two seasons following two back surgeries to repair multiple herniated disks in her spine that were pressing on a nerve.

Washington has been a different team without Delle Donne as one would expect. It shot 36.9 percent without her Thursday night in a 77-65 road loss to the New York Liberty.

“Delle Donne sitting out (Thursday) night makes you believe that she’s full-go on Sunday,” Miller said. “They’re a completely team with her. …They’re a really talented team. They’re a really talented home team.

“It’s our third game in five days, so it’s not an easy game to prep for, but you know we’ll be ready.”

The Mystics have been one among the best defensive teams holding opponents to 43.2 percent shooting. They scored 35 points on 23 Sun turnovers in their first meeting.
