Three games in four days took a toll on the Phoenix Mercury as injuries limited the depth in Monday’s 83-72 loss to the Connecticut Sun at Footprint Center.

Against a dynamic team like the Sun, with the second-best record in the WNBA, the Mercury were a step slow and were decimated by the Sun’s depth. Four of the five starters were in double figures with Brionna Jones leading with 18 points. The Sun also played eight players but outscored the Mercury’s bench, 20-2.

The Mercury (9-10) had a short bench against the Connecticut Sun (15-4) with starters Diana Taurasi and Becca Allen out for Monday’s contest. Guard Sophie Cunningham and forward Natasha Mack started in their place.

Taurasi dealt with back soreness, while Allen had a lower back issue. The two played the day before in a loss against the Indiana Fever. Taurasi played 32 minutes and logged 19 points and three assists. Allen recorded nine points on 25 minutes.

“When we were kids, we would play three games in one day and we’d be exhausted. I feel the same way right now,” guard Natasha Cloud said. “Moving forward, we need a decision to extend a few weeks of the season, especially with the Olympic year. It just protects players, mentally, emotionally, physically, all those things. We had a game yesterday at noon and we had a little bit of rest and are back at it again today. The toll it takes on your body from playing 30-plus minutes is a lot. You’re not going to hear any complaints from us, we showed up today.”

Brittney Griner and Kahleah Copper led all scorers with 21 points each. Griner sparked a big run in the fourth quarter with a much-needed 3-pointer. Griner, however, couldn’t make an impact on the boards, grabbing just two rebounds.

Copper had trouble seeing shots fall and went 1-for-4 in the first quarter. She managed seven field goals on 16 attempts, including one 3-pointer.

Rebounding was the difference in the game as the Sun dominated the boards with 37 rebounds to the Mercury’s 18. The Mercury were outscored 11-2 in second-chance points.

The Mercury, who averaged 27.8 3-point attempts, couldn’t find an answer from beyond the arc and shot 3-for-17 (17.6%).

Phoenix cut a 10-point deficit to three during the fourth quarter when Cloud assisted on Mack’s layup to start a 7-0 run. Cloud helped make it a close game with the Sun, getting her fourth double-double of the season with 18 points and 10 assists.

But the Sun edged the Mercury with 10 points on 11 free throw attempts and pulled ahead.

“It was our third game in four nights and we were playing eight people. I was proud of the way we competed, I don’t think you saw the best version of ourselves tonight. Everything was a little bit of a step slow,” head coach Nate Tibbetts said.

Guard Charisma Osborne was out with a left lower leg injury, which made Sug Sutton, Liz Dixon, and Mikiah Herbert Harrigan the only available options off the bench.
