PHOENIX -- Samantha Prahalis scored seven of her 15 points in the final 2:02 and made a tiebreaking layup with 23 seconds left and the Phoenix Mercury got past the Washington Mystics 80-77 on Wednesday night.
Washington's Monique Currie missed a driving shot in the lane with 4.9 seconds remaining and teammate Michelle Snow and Avery Warley got tied up on the rebound.
Officials called the Mystics for a jump ball violation on the ensuing jump with 1.5 seconds left. Krystal Thomas made a free throw for the final margin.
Down 74-69 with 2:26 left, Prahalis and DeWanna Bonner hit back-to-back 3-pointers within 33 seconds for the Mercury. Washington's Crystal Langhorne then missed an 18-footer with 44 seconds left, setting up the Mercury's winning possession.
Bonner led the Mercury (3-7) with 19 points and had seven rebounds and Thomas added 15.
Snow scored nine of her 21 in the fourth quarter and had nine rebounds to lead the Mystics (2-7) while Currie scored season-high 20 points.
Washington has lost six of seven.
Phoenix had just eight players in uniform as second-leading scorer Candice Dupree sat out with a left knee contusion suffered in Sunday's loss to Tulsa. Backup center Nakia Sanford also was out with an injury on Wednesday and All-Star Diana Taurasi remains sidelined by a strained left hip flexor. Phoenix is 1-5 with Taurasi out of the lineup.
After missing five of its first six shots, Washington made six straight to erase an early deficit. Currie made two 3-pointers and had 11 points as the teams were tied at 26 after one quarter.
Snow had 12 points for Washington as the Mystics took a 41-40 lead at the break.
Currie had six points in the third, including four in the final 1:37 to help the Mystics take a 60-57 advantage into the final period.
