Samantha Lyne is known to many fans as the wife of legendary bull rider J.B. Mauney, but her own story began in professional rodeo. A barrel racer from Texas, she competed at a high level and qualified for the 2014 Wrangler National Finals Rodeo (NFR). Her family background is also deeply connected to Western sports: her father, Phil Lyne, is a decorated rodeo champion.
Today, Samantha Lyne remains connected to the horse and rodeo world through her family, breeding interests and continued involvement with barrel racing.
Who Is Samantha Lyne?
Samantha Lyne is a Texas-based barrel racer who grew up in a prominent rodeo family. Her father, Phil Lyne, was a five-time PRCA World Champion and became one of the best-known cowboys of his generation.
Rather than simply benefiting from that family connection, she developed her own career in barrel racing. Her competitive record eventually took her to the NFR in 2014, placing her among the leading barrel racers of that season.
Her career is particularly interesting because barrel racing and bull riding are different disciplines, yet both demand speed, timing, horsemanship and an understanding of competitive rodeo conditions.
Samantha Lyne’s Barrel Racing Career
The most significant competitive milestone in Samantha Lyne’s career came in 2014, when she qualified for the NFR in Las Vegas.
Contemporary Barrel Racing Report coverage from September 2014 placed Lyne 14th in the WPRA World Standings with $70,464 in earnings as the regular season approached its final stage. The report also highlighted her mare LK Watch Me Rock, known as “Pistoletta,” as an important part of her campaign.
Her NFR appearance established her as more than a member of a famous rodeo family. She had earned a place among the sport’s elite competitors through her own results.

Samantha Lyne’s competitive career also demonstrates how important the horse is to professional barrel racing. A rider’s results depend heavily on developing a partnership with a horse capable of handling speed, turns and pressure.
Her Connection to LK Watch Me Rock
LK Watch Me Rock became closely associated with Lyne’s professional career. The mare helped her accumulate significant earnings during the 2014 season and was the horse she relied on during the final push toward the NFR.
That connection has continued to influence the Lyne family’s place in barrel racing. A later generation of the same bloodline produced horses that remained relevant in competition.
Samantha Lyne and J.B. Mauney
Samantha Lyne married J.B. Mauney in 2017. Mauney became one of professional bull riding’s most recognizable figures, winning two PBR World Championships and qualifying for the PBR World Finals 15 consecutive times from 2006 through 2020.
The relationship brought together two people with established backgrounds in rodeo. Mauney competed in bull riding at the highest level, while Samantha had already built her own record in barrel racing.
Their connection was also visible during Mauney’s career. PBR coverage in 2019 identified Samantha as his wife and showed the couple traveling with their young son while Mauney competed.
Family and Life in Texas
Samantha Lyne and J.B. Mauney have a son, Jagger Briggs Mauney, who was born in January 2019. Mauney also has a daughter from a previous relationship.
The family has been associated with Texas for several years. PBR reported in 2019 that Mauney and Samantha were living in Cotulla, Texas, while the organization’s current athlete profile places the family in Stephenville, Texas.
Family life also intersects with their involvement in horses and Western sports. That makes Samantha’s story different from that of a celebrity spouse whose public identity comes primarily from a famous partner. Rodeo was already a central part of her life before her marriage to Mauney.
💡 Pro Tip: When researching a rodeo athlete, look beyond championship results. The horses, competition history and major qualifying events often provide a much clearer picture of the person’s actual career than celebrity coverage does.
Her Influence on the Next Generation of Barrel Racing
One of the more recent developments connected to Samantha Lyne involves horse breeding.
In 2025, WPRA reported that barrel racer Makenna Shook purchased XV Mario from Samantha Lyne Mauney. The horse is a son of RR Mistakelly and out of XV Watch Me Rock, whose lineage connects back to LK Watch Me Rock, the mare associated with Lyne’s 2014 NFR campaign.
A 2025 Barrel Racing Report entry also identified Samantha Lyne Mauney as the breeder of XV Mario.
That connection gives her story a longer arc: from competing at the NFR herself to having a horse from her breeding program compete successfully with another rider.
What Happened to J.B. Mauney’s Rodeo Career?
J.B. Mauney retired from bull riding in 2023 after suffering a neck injury at the Lewiston Round-Up in Idaho. His competitive career ended, but his involvement in professional bull riding did not stop there.
In 2024, he became head coach of the Oklahoma Wildcatters in the PBR Teams series. PBR described the appointment as his first coaching role and a return to the organization after his competitive career.
For Samantha, this means the family’s connection to professional rodeo continues even after her husband’s transition away from competition.
📌 Key Takeaway: Samantha Lyne built her own identity as a professional barrel racer and 2014 NFR qualifier before becoming widely known through her marriage to J.B. Mauney. Her family heritage, competitive career and involvement with horses remain important parts of her story.
