Fever 79, Sky 57
Tamika Catchings had 18 points and 12 rebounds and Indiana advanced to the WNBA's Eastern Conference finals by completing a best-of-three series sweep of Chicago with a victory Sunday.
Erlana Larkins added 14 points and Shavonte Zellous scored 10. The Fever (18-18) will play at either Atlanta or Washington in Game 1 of the conference finals on Thursday.
The Fever were the only WNBA team to reach the playoffs with a losing record. But Indiana took advantage of Chicago's poor shooting to defeat the Sky for the fifth straight time.
The Sky (24-12) missed their first six shots from the field, but took an early 6-3 lead by hitting 6-of-6 free throws. But Catchings scored six straight points for the Fever to give Indiana a lead it would never relinquish.
Sylvia Fowles led the Sky with 14 points. Epiphanny Prince scored 10 points, and WNBA Rookie of the Year Elena Delle Donne added 10 points, but was scoreless in the second half.
The Sky, in the playoffs for the first time in franchise history, shot just 17-of-57 from the field but were 22-of-28 from the free throw line on Sunday.
Before the game, Zellous was presented with the league's Most Improved Player award.
The Fever's 47-27 halftime lead was the largest in Indiana postseason history, and the Fever's largest halftime lead of the season. Indiana won its third consecutive playoff series as the lower-seeded team, including last season's Eastern Conference and WNBA Finals.
The Sky opened the second half with a 5-0 run, but Catchings scored on a layup, was fouled, and hit the free throw to put Indiana up 50-32. Chicago didn't get closer than 18 points the rest of the way.
Catchings' double-double was her 20th in 49 career playoff games. She moved into second on the league's all-time list for playoff rebounds. She was already the WNBA's leader in playoff free throws and steals and is third in scoring.
Indiana was 27-of-59 from the field and 20-of-25 from the line.
Lynx 58, Storm 55
Seimone Augustus hit a 15-foot jumper with 21.1 seconds left and Minnesota held off Seattle for a sweep of the best-of-three Western Conference semifinals.
Maya Moore scored 22 points and Rebekkah Brunson had 15 points and 13 rebounds for Minnesota, which won the WNBA title in 2011 and lost to Indiana in last year's finals.
Minnesota opens the Western Conference finals this week against the winner of the Los Angeles-Phoenix series, which will be decided on today.
Tina Thompson made a driving layup to put the Storm up 55-54 with 1:20 remaining, their first lead since late in the second quarter.
But Augustus, who had 10 points, responded with her jumper from the right side.
Brunson hit two free throws with 11.6 second left for the final margin.
Noelle Quinn missed a driving layup in the final seconds for Seattle, which rebounded the miss but couldn't get off another shot in the game played at the Tacoma Dome because KeyArena in Seattle was unavailable due to a scheduling conflict with a Microcsoft event.
Thompson had 13 points and nine rebounds in the final game of her 17-year career. She announced before the season that she would retire at the end of the year. The 38-year-old forward is the WNBA's career scoring leader and won four league titles with Houston.
Tanisha Wright led Seattle with 16 points. Camille Little added 14 points as the Storm lost in the first round to the Lynx for the second straight year. Seattle made its league record 10th consecutive playoff appearance.
Moore scored seven in the third quarter to help the Lynx to a 42-39 lead. Wright scored six for the Storm.
Moore scored 12 as the teams were tied at 28 at halftime. The Storm outscored Minnesota 12-8 in the second quarter as the Lynx made only 4 of 15 shots from the field.
The Lynx beat the Storm 2-1 in last year's Western Conference semifinals.
Sparks 82, Mercury 73
Candace Parker had 31 points and 11 rebounds to help Los Angeles beat Phoenix, evening the WNBA Western Conference semifinal series.
Nneka Ogwumike also had a double-double with 15 points and 11 rebounds, Lindsey Harding scored 13 points and Alana Beard added 12 for the Sparks. Two days after receiving the league's MVP award for the second time, Parker shot 13 for 24 from the field and 5 for 6 on free throws.
Diana Taurasi, who scored 30 points in Phoenix's win at Los Angeles in Game 1 on Thursday, had 20 points on 6-of-18 shooting. However, after trailing at halftime for the second straight game, the Mercury couldn't rally for the win this time.
Brittney Griner scored 18 points and Candice Dupree added 16 points and nine rebounds for the Mercury.
The deciding game Game 3 will be tonight in Los Angeles.
Parker had 15 points and four rebounds in the second quarter as the Sparks extended their early lead to a 44-30 advantage at the break and then held off Phoenix in the second half.
Los Angeles led by 13 in the fourth quarter.
The Mercury chipped away a bit in the third period with Taurasi getting 11 points to help her team get within 10 going into the final period but Phoenix never got the deficit to single digits until the final 3:07.
The Mercury pulled to 76-71 on Taurasi's two free throws with 34.8 seconds remaining, but Los Angeles made 6 of 8 from the line the rest of the way to seal the win.
