Samantha Lyne is a barrel racer and 2014 National Finals Rodeo qualifier who is also widely known as J.B. Mauney’s wife and the daughter of rodeo champion Phil Lyne. Her own competitive record, however, gives readers plenty to discover beyond those family connections. She earned a place at one of rodeo’s most demanding championships before marrying the celebrated bull rider.
Her story connects competitive riding, a distinguished Texas rodeo family and horses whose influence continued beyond her own NFR appearance. Understanding those connections also helps explain what her achievements mean, which horses shaped her career and how her name remains relevant within barrel racing today.

Who Is Samantha Lyne?
Samantha belongs to a rodeo family, but she established her own place in the sport through barrel racing. Her 2014 qualification for the Wrangler National Finals Rodeo brought her into the season’s elite field and remains the clearest milestone in her competitive career. A 2014 Barrel Horse News profile also reported that Samantha graduated from Texas State University in Interior Design.
Readers may encounter her as Samantha Lyne, Samantha Mauney or Samantha Lyne Mauney. Contemporary competition coverage generally uses Lyne, while later reporting uses her married name. WPRA coverage directly connects these identities through her NFR background and subsequent involvement with XV Mario.
That distinction is useful when looking through older results. A search focused entirely on her husband can overlook the earlier records that explain her sporting reputation.
Family Background and Phil Lyne’s Rodeo Legacy
Her father, Phil Lyne, was one of professional rodeo’s most versatile champions. His five world championships included all-around and tie-down roping titles in both 1971 and 1972, followed by the steer roping world championship in 1990. These achievements covered different disciplines and stretched across nearly two decades.
The all-around title recognizes success across rodeo events. Tie-down roping and steer roping require their own specialized skills, making Phil’s record particularly notable. His career provides meaningful context for Samantha’s background without replacing the need to recognize her individual results.
Barrel Horse News identified Samantha as his younger daughter when profiling her ahead of the 2014 NFR. Her own event involved a different challenge: guiding a horse through a fast, accurate barrel pattern against the clock.
Phil died on August 14, 2026, at age 79, as confirmed by his funeral-home obituary. His championship record remains an important part of the family’s rodeo history.
Samantha Lyne’s Barrel Racing Career
A contemporary profile lists Samantha’s WPRA joining year as 2001. By 2014, she had reached her first NFR, making that qualification a milestone achieved years after entering the association.
Her pre-NFR profile recorded 100 rodeos attended during the 2014 season and approximately $70,577 in qualifying earnings. Those figures show the scale of the campaign behind her trip to Las Vegas. Qualification reflected a season of competition, rather than a single standout appearance.
For readers unfamiliar with professional rodeo, that distinction matters. An athlete can deliver an excellent run at one event, but building a qualifying season requires repeated results while managing travel, horses and changing competition environments.
What Does a Barrel Racer Do?
Barrel racing is a timed event in which a horse and rider follow a cloverleaf pattern around three barrels. The aim is to complete the course as quickly as possible while keeping the barrels standing. Under standard professional rodeo rules, each knocked-over barrel adds five seconds to the time.
Speed alone is therefore insufficient. The rider must guide the horse into efficient turns, maintain balance and accelerate between barrels. A wide turn costs time, while an overly tight approach risks a penalty.
This helps explain why a barrel racer’s horse is central to the story. The result belongs to a partnership whose timing and preparation must come together in a brief run.
Her 2014 NFR Qualification and Results
Samantha entered the 2014 NFR in 14th place in the qualifying standings. After the finals, she finished 15th in the year-end world standings. These are different measurements taken at different stages of the season.
The published final results provide a clearer breakdown:
| 2014 result | Amount or placing |
|---|---|
| Earnings before the NFR | $70,577.07 |
| Earnings at the NFR | $11,340.14 |
| Total world standings earnings | $81,917.21 |
| Final world standing | 15th |
At the ninth go-round of the 2014 NFR, Samantha completed a 13.94-second run to finish third, earning $11,340.14. These are competition earnings recorded for that season, rather than a calculation of personal wealth.
Her qualification should also be distinguished from a world championship. Fallon Taylor won the 2014 WPRA barrel racing world title. Samantha’s achievement was earning her place in the finals and competing against that championship field.
Keeping these categories separate makes her record easier to understand. Qualifying position, finals earnings and final world standing each describe a different part of the same season.
Pistoletta: The Horse Behind Her NFR Appearance
One of the most significant horses in Samantha’s career was LK Watch Me Rock, known as Pistoletta. The mare appears in her contemporary NFR profile alongside another horse, Java Buzz, called Java.
Pistoletta already had a competitive background before carrying Samantha to the finals. BarrelRacing.com documents that Brittany Pozzi Tonozzi trained and rode the mare before LaTricia Duke took over the reins during part of her early career.
Duke added an Ardmore Futurity championship and reserve finishes at the JB Quarter Horses Futurity and WPRA World Finals to the mare’s record. The same account identifies Pistoletta as the horse that later carried Samantha to the 2014 NFR.
This history highlights how several horse professionals can contribute to a successful competitor. Breeding, early training and later riding partnerships all form part of the horse’s development.
For Samantha, Pistoletta became both a major competition partner and a connection to a later generation of successful barrel horses.
Marriage to J.B. Mauney and Family Life
Samantha married J.B. Mauney in 2017. He won PBR world championships in 2013 and 2015, establishing himself as one of the best-known competitors in bull riding.
Their sports involve different demands. Samantha’s event depends on a trained horse-and-rider partnership completing a timed course. Mauney’s reputation developed through scored rides on powerful bucking bulls. Both careers nevertheless placed them within the wider professional rodeo community.
The couple welcomed their son, Jagger Briggs Mauney, in January 2019. PBR reported the birth at the time. Separate PBR coverage also identifies Mauney’s daughter, Bella; she should not be confused with the child he welcomed with Samantha.
PBR’s official profile places Mauney and Samantha in Stephenville, Texas. It also records the neck injury that ended his bull-riding career in 2023, marking a major change in the family’s connection to professional competition.
Her Continuing Connection to Barrel Horses
Samantha’s influence within barrel racing extends beyond her own results. WPRA reporting confirms that she raised XV Mario, the gelding Makenna Shook purchased in March 2025.
Mario was patterned by Brandon Cullins, meaning he received training in negotiating the barrel course. His pedigree also connects directly to Samantha’s NFR career: his mother, XV Watch Me Rock, is a daughter of Pistoletta.
This creates a clear link between generations of horses. The mare associated with Samantha’s 2014 achievement later appeared in the maternal line of a young horse succeeding with another rider.
BarrelRacing.com’s July 2025 reporting described Shook and Mario building momentum through results at rodeos including Casper, Wyoming. Their developing partnership illustrates why a horsewoman’s contribution can remain visible after a horse moves to a new owner.
XV Mario’s Record Run—and the Later Update
On August 16, 2025, Shook and XV Mario completed a standard-pattern run in 16.53 seconds at Burley, Idaho. WPRA reported it as a record-setting performance at a PRCA rodeo. Samantha raised the horse; Shook was the rider responsible for the competitive run.
That result should now be described as a former record. WPRA subsequently reported Sydney Graham’s 16.49-second performance in 2026, followed by Kathy Grimes and KG Just Money lowering the mark to 16.31 seconds.
The later results do not diminish Mario’s achievement. They simply place it correctly within the sport’s evolving record book.
Understanding Her Career Earnings
Published rodeo earnings offer a concrete way to understand Samantha’s competitive results. However, they do not establish her net worth, annual household income or the value of any horses she has owned.
Prize money is also different from profit. Competition involves expenses, and a standings total does not account for an athlete’s complete financial circumstances.
For a useful biography, the documented season results provide more meaningful information than an unsupported wealth estimate. They show what she earned in competition and where she finished without implying access to private financial records.
Conclusion
Samantha Lyne’s story brings together personal achievement, family history and an ongoing contribution to barrel racing through horses. Her NFR appearance provides a clear competitive milestone, while the later success of XV Mario adds another dimension to her record.
Her marriage to J.B. Mauney explains much of the wider public interest, but understanding her own sport gives readers a fuller picture. She belongs in the story of rodeo through both her family connections and the results associated with her own riding and horses.
