SEATTLE (AP) — League MVP Breanna Stewart scored 19 of her 28 points in the first half, Jewell Loyd added 23 — including Seattle’s final seven points — and the Storm held on to beat the Phoenix Mercury 91-87 on Sunday in Game 1 of their WNBA semifinal series.

After posting the best record in the league during the regular season, Seattle got a week of rest before opening the semifinals at home. For the most part there was no rust from the long layoff, but Phoenix made the final minutes uncomfortable after cutting a 16-point deficit to two.

Loyd came up with a pair of clutch baskets, including a 15-footer with 1 minute left to beat the shot clock and pushed Seattle’s lead to four.

DeWanna Bonner led Phoenix with 27 points and 13 rebounds, and Diana Taurasi added 25 points. But the third of Phoenix’s big three stars, Brittney Griner, was held to 13 points and battled foul trouble throughout.

Natasha Howard added 20 points and Sue Bird had 10 points and 10 assists for Seattle. The Storm finished with 13 3-pointers, 10 in the first half.

Phoenix opened the playoff with a win at home over Dallas before traveling cross country to knock out Connecticut, and taking another cross country trip to Seattle to open the semifinals. If there was any fatigue, Phoenix didn’t show it in the fourth quarter, outscoring Seattle 20-12 and making for a tense final minute.

Seattle led by 70-54 after Stewart’s sixth 3-pointer midway through the third quarter, but Phoenix had a fourth-quarter surge waiting. Stewart scored on the low block with 4:57 left to push Seattle’s lead back to 10. Phoenix responded with a 13-5 surge led by Taurasi. She followed up a deep 3-pointer with a pass to a cutting Bonner for a basket. Stewart missed twice near the basket on Seattle’s next possession and Griner’s second-chance basket with 1:40 remaining pulled the Mercury within 89-87.

Alysha Clark missed an open 3 for Seattle, but Stewart’s offensive rebound led to Loyd’s 15-footer that barely beat the shot clock to push Seattle’s lead to four.
