Kelly Miller scored 18 points for Minnesota and the Lynx made 16 3-pointers and hung on for a 100-95 victory over the Sacramento Monarchs on Friday night.
The Lynx, who shot 52.4 percent from the floor and 57.1 percent on 3-pointers, set a WNBA season high and a franchise record for 3-pointers in a game.
Roneeka Hodges (five 3-pointers) and Nicky Anosike each added 17 for a Lynx team that had six players in double figures. Hamchetou Maiga-Ba led Sacramento with 20 points while Nicole Powell added 18.
The victory snaps Minnesota's six-game losing streak and the Lynx (12-16) lead San Antonio by one game in the race for the final Western Conference playoff spot.
Sacramento is 3 1/2 games out of the final playoff spot with only five games remaining.
While the Lynx, who made 10 of their first 13 3-point attempts, scored at a quick pace from the beginning, they had to hang on for the victory. Trailing by 11 with 2:50 to play, Sacramento (9-20) scored eight straight points and were within three 96-93 with 31.8 seconds to play.
Hodges, however, made a pair of free throws with 10.2 seconds to play to secure the victory.
Minnesota set a franchise record for points in a half while taking a 64-50 lead at the break. The Lynx accomplished that by shooting 69.7 percent from the floor and 75 percent from behind the 3-point line (9 for 12).
Before the game, Sacramento signed guard Lisa Willis to a seven-day contract. Willis previously played for Los Angeles and New York and has averaged 4.6 points over three WNBA seasons.
