HIGH-FLYING OFFENSE, STOUT DEFENSE AND YNT PLAYERS SET TO SHINE IN U-18/19 GIRLS' PLAYOFFS SEMIFINALS

After 24 games of group stage play, only four teams remain in the inaugural U-18/19 Girls' Academy Playoffs. The final four match-ups feature plenty of intrigue, and the quartet will compete to be crowned the first-ever Girls' Academy Champion. Here's what you should know about Tuesday's pair of semifinal showdowns, both streamed live on ussoccerda.com, the Development Academy Facebook page, and U.S. Soccer's YouTube channel.

BOSTON BREAKERS ACADEMY VS. SOLAR SOCCER CLUB - 3:00 P.M. PT

The first semifinal of the day will pit the Academy's most-dynamic regular season offense against the Playoffs' highest-scoring squad. The No. 4 overall seed, Boston Breakers Academy found the back of the net more than any team in the country this season, putting up 169 goals in 28 regular season games. Mary Kate McGuire was No. 2 on the Academy's goal-scoring leaderboard, netting 32 times in just 13 games played. She led a lethal Boston attack that also featured Gabriella Del Pico, who added 22 goals, and Mia Otero, who scored 20 times in just 14 appearances. At the Playoffs, Catherine Barry has headed the Breakers' offensive efforts, scoring three goals across the team's group stage games.

Solar Soccer Club's offense has been electric in Oceanside, putting up 14 goals in its three group fixtures. With nine goals so far, Solar's Trinity Byars has caught fire in Oceanside. She bagged four goals in both Solar's opening victory over Michigan Hawks as well as Wednesday's 5-2 win over San Diego Surf. The U-16 Girls' National Team call-up also netted five times for the USA en route to the team's run to the Torneo delle Nazioni title in April. Midifelder Sam Meza is back with Solar just two weeks after helping the U-17 Women's National Team take home the Concacaf Women's U-17 Championship. Meza played in four of the USA's five games at the FIFA U-17 Women's World Cup qualifying tournament, and scored in Solar's final group stage match.

CROSSFIRE PREMIER VS. LAFC SLAMMERS - 5:30 P.M. PT

The second semifinal is headlined by No. 1 overall seed, Crossfire Premier. The Northwest Division's top finisher rode the Academy's strongest defense to an undefeated regular season, compiling a 22-0-2 record. While Crossfire suffered its first loss of the season on Tuesday to Sky Blue-PDA, the Kirikland, Wash. based club had already booked its passage to the semifinals. Its lockdown defense allowed just 13 goals in 24 regular season games, as players like Shay Adams, Katelyn Duong and Britney Weedman consistently played key roles down the stretch.

LAFC Slammers rode a hot streak into the Playoffs and enter the semifinals as the only non-top-four seed. The Southwest Division champs won all three of their group stage games in Oceanside and are undefeated in their last 15 games. Kate Wiesner spent time captaining the U-17s at World Cup qualifying, and her three goals have led the postseason charge for Slammers. Jenna Nighswonger has also scored for the SoCal squad in the Playoffs. This year, she captained the U-18 WNT at March's La Manga tournament and bagged a brace against Switzerland in April.
