Early Life & Background
Sean Patrick Gilmartin was born on May 8, 1990, in Moorpark, California, and raised in a family deeply connected to baseball. His father, Paul J. Gilmartin, worked as a chiropractor and had played professionally. His brother Michael was also drafted by an MLB team, and other relatives spent time in the minor leagues. This environment shaped his early interest in the sport.
He attended Crespi Carmelite High School in Encino, California, where he showed promise as both a pitcher and position player. The San Diego Padres selected him in the 31st round of the 2008 MLB Draft, but he chose college instead. At Florida State University, Gilmartin developed into a standout left-handed pitcher. He earned All-American honors and helped the Seminoles reach the College World Series. His combination of size, command, and a strong changeup made him one of the more polished college arms available in the 2011 draft.
Career Beginnings
The Atlanta Braves selected Gilmartin 28th overall in the first round of the 2011 MLB Draft and signed him to a $1.134 million bonus. He spent several seasons developing in the Braves’ minor league system before being traded to the Minnesota Twins in 2013. In the 2014 Rule 5 Draft, the New York Mets claimed him, giving him a clear path to the majors.
Gilmartin made his MLB debut on April 10, 2015, against the Braves, retiring the two batters he faced. That rookie season proved to be his most productive. Working primarily out of the bullpen, he posted a 3-2 record with a 2.67 ERA over 57.1 innings and 54 strikeouts. He appeared in the postseason as the Mets advanced to the World Series.
Rise to Fame
While never a high-profile starter, Gilmartin carved out a role as a reliable left-handed reliever. He remained with the Mets through 2017, then signed with the Baltimore Orioles for the 2018 and 2019 seasons. In 2020, he appeared in two games for the Tampa Bay Rays. Across six major league seasons, he finished with a 4-5 record, 4.34 ERA, and 90 strikeouts in 112 innings.
After his final MLB appearance in 2020, he pitched briefly in the independent Atlantic League with the Long Island Ducks before retiring during the 2021-22 offseason. His most visible moment remains the 2015 Mets postseason run, when a first-round draft pick from Florida State contributed to a championship contender.
Net Worth Breakdown
Sean Gilmartin’s net worth is estimated at approximately $3 million as of 2026. Career earnings total roughly $2.02 million according to available contract data, with the bulk coming from the $1.134 million signing bonus and subsequent major league and minor league salaries. One source places total baseball-related earnings closer to $3.2 million when including all compensation.
After retirement, he has worked as a private pitching instructor and consultant in Florida, generating additional income in the estimated range of $60,000 to $150,000 annually in recent years. The couple has also invested in real estate in the Tampa area. Public reports note a home purchased around 2017 that later carried a higher valuation. These factors, combined with careful management of earlier earnings, support the current net worth estimates that range from $2 million to $5 million across various outlets, with $3 million appearing most frequently.
Personal Life
Gilmartin married Kayleigh McEnany on November 18, 2017. The couple began dating in 2015 after connecting through social media while McEnany was studying at Harvard Law School and interning in New York. They have three children: daughter Blake (born November 2019), son Nash (born 2022), and daughter Avery Grace (born June 2025).
The family lives in Florida. Gilmartin has largely stayed out of the political spotlight that surrounds his wife’s career as a Fox News host and former White House Press Secretary. He has described himself as an avid hunter and outdoorsman, frequently sharing photos of hunting trips and time with his dogs on social media.

Public information on formal business ownership or large-scale philanthropy is limited. His primary post-playing activity has been private pitching instruction and consulting in the Florida area. No major brand endorsements or company ownerships have been widely reported. Charitable involvement, if any, has remained private.
Social Media Influence

His X account (@GilmartinSean) has roughly 25,000 followers and focuses on baseball memories, Florida State updates, family moments, and outdoor activities. His Instagram (@gilmartin_sean36) features hunting photos, family life, and occasional support for his wife’s projects.
