Delle Donne first in WNBA to join 50-40-90 club

WASHINGTON -- Elena Delle Donne scored 25 points, making WNBA history along the way, and the regular-season champion Washington Mystics raced past the Chicago Sky 100-86 on Sunday.

She became the first player in WNBA history to shoot more than 50% from the field (220-of-427), 40% from 3-point range (52-of-121) and 90% from the foul line (114-of -17). Her free throw percentage of 97.4 is a record for a player with at least 100 attempts.

Current and former NBA luminaries took to social media Sunday night to congratulate Delle Donne on the unprecedented feat.

The Mystics (26-8), who lost to Seattle in the finals last season, have a double bye into the semifinals and home-court advantage throughout the postseason. The Sky (20-14) are the No. 5 seed and play No. 8 Phoenix at home Wednesday in the single-elimination opening round of the playoffs.

Chicago's Courtney Vandersloot had six assists to become the first player in league history to reach 300 in a season, which she did exactly, and the first player to average at least 9 assists a game for a season (9.1).

Washington led 56-39 at the half, but Chicago cut the lead to six in the final minute of the third quarter. Tianna Hawkins answered with a layup for the Mystics, and after a Sky miss, Myisha Hines-Allen hit a 3 with 1.5 seconds left to restore the double-figure lead. Chicago never challenged in the fourth quarter.

Diamond DeShields led the Sky with 16 points. Allie Quigley added 13 with three 3-pointers, giving her a Chicago-record 80 for the season.
