Major League Baseball Career
Sean’s main source of income came from professional baseball. After a strong college career, he entered the 2011 MLB Draft and quickly became a high‑value prospect.
He was selected 28th overall in the 2011 MLB Draft by the Atlanta Braves, as confirmed in the Baseball‑Reference player record. That selection brought a seven‑figure signing bonus.
After several seasons in the minors, he finally reached the big leagues. According to ESPN’s player profile, he made his MLB debut on April 10, 2015 with the New York Mets.
Sean later pitched for multiple teams, including the Mets, Baltimore Orioles, and Tampa Bay Rays. During his MLB career he appeared in 81 games and recorded 90 strikeouts.
College Baseball and Draft Value
Before turning pro, Sean developed his skills at Florida State University. There he became one of the top pitchers in college baseball.
As a junior, he was named an All‑American pitcher for the Seminoles. That recognition helped raise his draft stock significantly.
Strong performances in college made him attractive to MLB scouts. By the time he entered the draft, teams saw him as a polished left‑handed pitcher with strong control and durability.
Coaching and Baseball Development Work
After stepping away from active professional play, Sean remained connected to the sport. He now works with young pitchers and developing players.
His experience in the majors makes him a valuable mentor. Many former players follow a similar path by teaching pitching mechanics, strategy, and mental preparation.
Coaching also allows him to stay close to baseball without the travel demands of a professional schedule.
From California Kid to Major League Pitcher
Sean grew up in Moorpark, California. His father worked as a chiropractor, and his family supported his early love for sports.
He attended Crespi Carmelite High School in Encino. During high school, his pitching talent already caught the attention of professional scouts.
The San Diego Padres actually drafted him in the 31st round of the 2008 MLB Draft. However, he chose college instead of signing.
That decision proved important. By attending Florida State and improving his skills, he later became a first‑round pick.
The Mets Breakthrough and World Series Run
Sean’s biggest professional moment came during his time with the New York Mets.
In the 2014 Rule 5 Draft, the Mets selected him from the Minnesota Twins organization. The team had to keep him on the major league roster for the entire 2015 season.
He earned a spot in the bullpen and delivered strong performances. During the 2015 season he posted a 2.67 ERA in 50 appearances.
That year the Mets reached the World Series. While not a headline star, Sean played a valuable role as a reliable relief pitcher throughout the season.
Later Teams and Final Playing Years
After his early success in New York, Sean’s career included several team changes. He moved between major league rosters and minor league assignments.
He later spent time with the Baltimore Orioles and Tampa Bay Rays. Injuries and roster competition made consistent MLB playing time more difficult.
His final major league appearance came in August 2020 while pitching for Tampa Bay.
After the 2021 season in independent baseball, he stepped away from professional play and shifted toward mentoring and family life.
Family Life With Kayleigh McEnany
Sean married political commentator Kayleigh McEnany in November 2017. She later became widely known as the White House Press Secretary during the Trump administration.
The couple has built a family together in Florida. They share three children and often keep their personal life relatively private.
Sean generally keeps a low public profile while supporting his wife’s media career and raising their children.
