DES MOINES -- A huge all-around performance by sophomore Alexis Conaway help put MOC-Floyd Valley in the Class 3A state championship game.

Conaway made plays with her shooting, passing and defense as the second-ranked Lady Dutch remained unbeaten with a 63-53 victory over No. 3 Sioux City Bishop Heelan in an overtime semifinal game Thursday at Wells Fargo Arena.

In just the overtime alone, Conaway scored eight points, assisted on a basket and blocked two shots. She finished with 16 points, 12 rebounds, seven blocks, six assists and five steals.

Lauren McDonald led the Lady Dutch with 18 points and Caitlyn Van Es scored 12. MOC-Floyd Valley hiked its record to 27-0 and will try to win its first state basketball title at 6 p.m. Saturday against Davenport Assumption. (Boxscore)

Madison Yohe led Heelan with 20 points, Alex Fuller scored 12 and Natalie Vondrak added 10 to go with seven rebounds. The Crusaders, state champs in 2008 and 2010, finished 24-2.

Bishop Heelan appeared to be in control when it opened a 44-34 lead early in the fourth quarter. But MOC-Floyd Valley stormed back with 13 straight points to take the lead. McDonald scored five points in the stretch, while Conaway and Van Es each had four.

The Lady Dutch eventually opened a 51-46 lead before Heelan rallied to tie it at 51 on Yohe's layup and send the game into overtime. That's when Conaway, a 5-foot-11 guard, took over.

She drove for a basket, then threw a long pass to Emily McDonald for a layup that put the Lady Dutch ahead to stay at 55-53. After Lauren McDonald scored inside, Conaway did the rest -- stealing the ball and driving the length of the court for a layup, sinking two free throws, then swatting away Bishop Heelan's final shot and taking the ball in for another layup.

DAVENPORT ASSUMPTION 70, BALLARD 29 -- Davenport Assumption will end the season in a familiar setting.

Sharp-shooting guard Danielle Moore scored 25 points and center Hailey Schneden put up a triple double to lead the defending champions back to the Class 3A title game.

Fourth-ranked Assumption jumped to an 8-1 lead and was in control all the way. Moore scored 15 points in the second quarter alone to help the Knights build a 36-17 halftime lead and they continued to pull away in the second half.

Moore went 4-for-6 from 3-point range and shot 8-for-10 overall. Schneden totaled 12 points, 10 rebounds and a 3A record 13 blocks, breaking the old record of eight set in 1995 by Vinton-Shellsburg's Monica Huelman, who'll be inducted into the IGHSAU Hall of Fame Friday night. (Boxscore)

The overall record for a state tournament game is 15 by Muscatine's Jenny Noll in 1991.

It was the second big game at state for Moore, who scored 23 points in the opening round against Glenwood.

Assumption improved to 24-2 and will play second-ranked MOC-Floyd Valley in the title game at 6 p.m. Saturday. Assumption beat Mount Vernon in last year's championship game and won the Class 2A title in 2008.

Unranked Ballard upset No. 1 Benton Community in the first round to reach the semifinals for the seventh straight year. But Moore's shooting and Assumption's depth proved too much for the Bombers, who finished 19-7.

Katie Ahrenholtz led Ballard with 10 points and 11 rebounds. Rachel Sage added eight points for Ballard and Makenzie Ihle scored six.
