Growing up in Gramercy with two brothers, Maria Detillier gravitated towards athletics, competing in softball, soccer, volleyball and swimming. 

The four-sport athlete shined in whatever sport was in season, collecting a slew of accolades in each of the four sports she participated in for Lutcher High School. 

Detillier collected defensive MVP in volleyball and offensive MVP in soccer, as well as being a three-time all-state performer on the softball diamond and a four-time state qualifier in swimming. 

Her talent was on full display, earning a softball scholarship from Southeastern to play for Head Coach Rick Fremin, where she would become a four-year starter, two-time all-conference performer and four-time all-Louisiana selection, leaving a lasting legacy on the program. 

“Maria Detillier is one of the best players I have ever had the pleasure of coaching, especially when it comes to off-the-field leadership and her ability to positively influence and lead the locker room. That type of leadership is extremely rare in today’s game, but she possessed it,” said Fremin. 

As a true freshman, Detillier seized the moment instantly, starting in 56 of SLU’s 60 contests at third base during the 2023 season, helping the Lady Lions to a 47-14 mark, which was at the time a school record for wins in a single season. 

Unfortunately, the Green and Gold (19-5 SLC) finished two games behind McNeese (21-3 SLC) in the regular season standings and fell to the Cowgirls in the Southland Conference Tournament Championship in Lake Charles, 1-0 in extra innings (8), missing out on the NCAA Tournament. 

Detillier led the Southland in runs (46) and sacrifice bunts (12) and was top 10 in the league in batting average (.333, 10th), OPS (.921, 9th), hits (56, 8th), RBI (31, 10th), doubles (11, 8th), home runs (5, 9th), total bases (86, 4th), sacrifice flies (5, 4th), stolen bases (17, 9th) and walks (23, 5th). 

She entered her sophomore season already one of the key cogs to an impressive SLU side. The Lady Lions finished 47-15 (17-7 SLC), breaking through as SLC Tournament champs on home turf, going on to beat Clemson 6-2 (twice) in the Tuscaloosa Regional, cementing Southeastern softball as a force to be reckoned with nationwide. 

The Lady Lions even took No. 14 Women’s College World Series participant Alabama to a pair of extra innings in the winner’s bracket matchup. 

“Beating Clemson twice was a pivotal turn for our program. We realized we can not only make it to regionals, but we can compete and beat Power 4 teams. It set a new standard,” said Detillier. 

Detillier started all 62 games at third base and finished in the top 10 in the conference in batting average (.354, 4th), OPS (.931, 8th), runs (42, 5th), hits (64, 4th), RBI (49, 2nd), doubles (11, 8th), triples (3, 5th), walks (22, 7th), sacrifice flies (3, 8th) and sacrifice bunts (7, 6th).

During her junior year, the Lady Lions set a program record for wins in a single season, reaching the half-century mark at 50-16 (21-6 SLC) and repeated as SLC Tournament champs, beating McNeese two out of three in Lake Charles after dropping Game 1 of the series. 

Detillier was named to the Southland Conference All-Tournament Team, recording five hits (one double), three runs, three RBI and three walks.

SLU went on to beat No. 10 LSU twice, 4-3 and 8-7, in the Baton Rouge Regional in two stunning upsets. Detillier played a pivotal role in the Lady Lions’ first victory over the Tigers, sprinting from first base all the way home and sliding in safely for what would be the winning run on a single to right center from Cydnee Schneider in the top of the seventh inning. 

Detillier then caught the final out of the contest on a lineout as the Southeastern players celebrated their historic feat, defeating LSU for just the second time in school history and the first since 2007. 

“Every game vs. LSU in the past was close, but we could never pull it off. Finally beating them was a dream come true,” said Detillier. 

LSU had beaten SLU 7-5 the year before on a walk-off three-run homer and 3-2 earlier in the season on a walk-off sac fly (both games in Baton Rouge). 

Detillier concluded her junior campaign as a First Team All-SLC performer, starting in all 63 games she appeared in. Detillier was top 10 in the SLC in batting average (.365, 10th), slugging percentage (.571, 7th), on base percentage (.431, 10th), OPS (1.002, 8th), runs (43, 8th), hits (69, 3rd), RBI (55, 2nd), doubles (15, 6th), triples (6, 2nd), sacrifice flies (3, 8th) and stolen bases (17, 8th). 

Detillier was named the 2025 Southland Conference Softball Student-Athlete of the Year and the 2024-2025 Southeastern Female Athlete of the Year for her accomplishments not only on the field but in the classroom as well. 

She graduated with a degree in accounting and finished with a 4.0 GPA, making the Spring Southland Conference Commissioner’s Honor Roll all four years as a student, as well as being a three-time First Team SLC All-Academic Softball Team selection. 

Detillier was also a 2025 Easton/NFCA All-America Scholar-Athlete. 

During Detillier’s senior season this past spring, SLU finished 46-16 (24-3 SLC) as SLC champs and Tuscaloosa Regional participants. Detillier was a First Team All-SLC selection once again and appeared on the All-Defensive Team as Southeastern notched another signature win, defeating No. 5 Oregon 4-2 during non-conference play early in the year. 

She was top 10 in the league in hits (58, 9th), RBI (56, 2nd), home runs (9, 5th) and sacrifice bunts (6, 6th). Defensively, Detillier finished third in the conference in assists with 116.  

Detillier finishes her illustrious career as the program’s all-time leader in runs (174), RBI (194), extra-base hits (87), total bases (395) and sacrifice flies (14).

“Believing in yourself and handling anything life throws your way. Softball is a sport of failure so you have to learn how to fail first. ‘Win or learn’ is what Coach always says. If you can handle failure on the softball field, then you can handle failure in life,” said Detillier on what softball taught her. 

She added her appreciation for Coach Fremin for fostering a faith-driven culture that puts personal development ahead of softball. 

“We were a better program because she wore the jersey at SLU with pride and consistently did things the right way. She never took shortcuts to achieve success. Instead, she was committed to self-improvement throughout her entire time here and continually worked to become a better player and person,” said Fremin. 

The 2026 Southland Conference Coach of the Year added, “It was truly an honor and a privilege to coach her.”

Detillier left the Lady Lion faithful with one final message: “Just keep showing up. I was here for four years, and each year it’s gotten better and better. Softball has gotten more and more recognition. I hope it keeps growing. SLU is a special place.”
