WASHINGTON (AP) — Elena Delle Donne scored 24 points and hit a crucial turnaround jumper late, Emma Meesseman added a career postseason high 27 points, and the Washington Mystics held on for a 97-95 victory over the Las Vegas Aces in Game 1 of their WNBA semifinal series Tuesday night.

Meesseman also bested her regular-season high of 25 for the top-seeded Mystics, who were playing their first postseason game since being swept by the Seattle Storm in last year's WNBA Finals.

In her first game in more than a month, Kristi Toliver added eight points, including a falling away, contested 3-pointer that stretched Washington's lead to 13 in the fourth quarter, an advantage that just barely held.

A'ja Wilson scored 23 points for Las Vegas, which twice got the deficit as close as two points in the final moments. Liz Cambage had 19 points and 12 rebounds, while Kayla McBride added 19 points.

Kelsey Plum had 16 points and nine assists, and missed a runner at the buzzer that would've forced overtime, two days after Dearica Hamby's 35-foot runner decided the Aces' 93-92, second-round win over Chicago.

After Toliver's 3-pointer stretched Washington's lead to 92-79, the Aces scored nine straight points to close the deficit to four, while twice forcing the Mystics into a shot-clock violation with the ball in Delle Donne's hands

Wilson's drive and layup closed it to 95-93 with 1:33 left, convincing Mystics coach Mike Thibault to call timeout.

After a missed shot on each end, Delle Donne hit a turnaround from near the right elbow to put the Mystics up four.

Plum answered with a layup on the other end to close it to two again. Delle Donne missed a jumper with under five seconds remaining, but while Plum was able to get an outlet pass and race inside the 3-point line, her runner under duress wouldn't fall at the buzzer.
