Veronica Burton scored a season-high 25 points and dished out eight assists, Gabby Williams also had 25 points, and the Golden State Valkyries held off the Phoenix Mercury 87-81 in a Commissioner's Cup game in San Francisco on Tuesday.

Kayla Thornton scored 12 points and Janelle Salaun added 11 for the Valkyries, who had their 17-point halftime lead trimmed to one before recovering in the final minutes to break a season-worst two-game losing streak.

Alyssa Thomas scored 20 of her 22 points in the second half for the Mercury, who had a two-game winning streak broken in the third game of a four-game road trip. Monique Akoa Makani put up a season-high 19 points.

Thomas, who missed the previous game with a calf injury, had nine assists and eight rebounds.

Akoa Makani's 3-pointer brought the Mercury (4-9, 2-2 Commissioner's Cup) within 76-75 with 3:09 left before Williams' three-point play gave the Valkyries an 84-78 lead with 1:39 remaining.

Thomas' three-point play closed the deficit to 84-81 on the next possession, but Williams intercepted Thomas' pass and made 1 of 2 free throws with 11 seconds left. Thornton later sank two to ice it.

Williams finished with three 3-pointers for the Valkyries, who wound up 10 of 29 (34.5%) from long distance. Golden State (7-5, 2-2) made 6 of 12 from beyond the arc in the first half, when it built a 49-32 lead. The Valkyries lead the WNBA with 12.1 treys per game and a 37.9% success rate from long range.

Williams sank three 3-pointers while Burton, Thornton and Salaun had two apiece. Burton went 9-for-11 at the free-throw line.

The Valkyries have won the first two in the season series, including a 95-79 home victory on May 10.

Akoa Makani, playing her sixth game after finishing her season in France, had six points and Thomas had four assists in a 13-0 run for a 16-10 Mercury lead in the first quarter. The Valkyries responded with a 12-2 run for a 22-18 edge.

The Valkyries closed the second quarter on an 18-5 run to take a 49-32 halftime lead, their largest advantage to that point. Burton had 10 points in the period as Golden State outscored Phoenix 27-14. Thomas and Mercury teammate Kahleah Copper were given technical fouls during the half-ending stretch.
