Trevian Girls Softball Association


The TGSA was originally established in 1980 to provide a top quality softball program for girls residing in the New Trier Township. The organization has since evolved to welcome players from neighboring and nearby communities as well. TGSA strives to maintain a strong base of community players in the organization, while also opening its doors to players from nearby areas seeking a top quality softball program.

TGSA is a non-profit organization run primarily by parent volunteers.  Through participation in the Trevian program, its players learn responsibility, hard work, teamwork and how these things add up to group success. Trevian players also build self-esteem and the confidence to take on difficult challenges later in life.

14 Blue Takes 4th at States

On Friday, July 8, the Trevian Blue 14U team traveled to Peoria to compete in the USSSA “B” State Championships, coming away with 4th Place.  After going 1-1 in pool play on Friday, the Trevians started slow in the double elimination tournament – dropping their first bracket game to Oly Fire.  But the Trevs were able to bounce back and win the next four elimination games.  The Trevians beat the Illinois Sluggers (10-2), the Illinois Valley Aftershock (7-6), and the Henry County Hurricanes (6-4).   In the fifth game of the day on Saturday, the Trevians knocked out tournament favorite, the Big Muddy Lunachicks, 11-3, with eight Trevian players combining for 15 hits in the contest. The win over the Lunachicks allowed the Trevians to advance into the final four on Sunday, ultimately losing their sixth bracket game 3-1 to Oly Fire.


12U Blue Runners-Up at Spartan Classic

After overcoming early setbacks during pool play, Anna Kasper's 12U Blue squad marched through bracket play and earned a runners-up finish in the Gold Division at the Spartan Classic Fastpitch Softball Tournament. The team swept through their first three bracket play games with a decisive 11-4 victory over the Park Ridge Pistols Blue, a hard-fought 10-8 win over the Grayslake Pride Black, and a solid 5-2 victory over the Huntley Red Raiders.  The girls were upended in their quest for the championship when they fell 10-6 to the Park Ridge Jr. Hawks on 6/26/16.  Despite falling short of achieving their team goal, the girls were thrilled with their runners-up finish and thoroughly enjoyed the overall tournament experience.  The deep run in Northbrook should give the 12U Blue girls added confidence as they tackle the back half of their 2016 season.


14U Blue Squad Strikes Again

The 14U Blue team went undefeated and took first place in the Green Division at the Spartan Classic Fastpitch Softball Tournament. The Trevs' speed and power were put on display throughout pool play and early bracket play games, as they outscored their opponents by 8 runs per game.  Through the first 5 games, the offensive attack was led by Claire VanDamme, Keeley Utz, and Bailey Williams. Stellar pitching performances were turned in by all 4 Trevian pitchers, including Beth Fisher, Hanna McDermott, Ria Patel, and Emmie Lacaeyse. 

Sunday's championship game against the Huntley Red Raiders was dramatic and exciting.  After giving up 5 runs early and trailing through 4 innings, the Trevians began chipping away at the lead by scoring one run in the bottom half of the 5th inning.  Then, in the 6th , Rachel Rane blasted a 2-out, bases-loaded triple to bring the Trevians within 1 run.  The girls were able to build on the momentum in the bottom of the seventh and plated two runs on a walk-off single by Brianna Reed.  The Trevians' 6-5 championship victory over Huntley in Northbrook was the 3rd tournament title of the summer season for the 14U Blue team.
