The Kid Who Chose College Over Cash
Sean Patrick Gilmartin was born on May 8, 1990, in Moorpark, California. He grew up in a house where baseball was more than a hobby—it was a language. His father, Paul Gilmartin, had played professional baseball before becoming a chiropractor. His older brother Michael reached the minor leagues. Two uncles also played professional baseball.
Baseball wasn’t something Sean picked up casually. It was inherited. It was in his DNA.
At Crespi Carmelite High School in Encino, California, his talent became undeniable. The San Diego Padres noticed. In the 2008 MLB Draft, they selected him in the 31st round.
Most teenagers would have signed immediately. A professional contract. Leaving high school. Living the dream.
Sean Gilmartin said no.
Instead, he accepted a baseball scholarship to Florida State University. He chose education. He chose development. He chose to become a better pitcher before signing professional contracts.
That single decision—turning down professional money as a teenager—proved to be one of the most financially consequential choices of his life.
The College Phenomenon Who Made Himself A First-Round Pick
At Florida State, Sean Gilmartin transformed from a promising high school pitcher into one of the premier college pitchers in America.
As a junior in 2011, he posted a record of 12 wins and 2 losses with a 2.09 ERA across 18 appearances. He earned first-team All-American honors from Baseball America. He helped lead the Seminoles to the College World Series.
By waiting, by improving, by dedicating himself to the craft, Sean Gilmartin had positioned himself to be drafted much higher than the 31st round that had selected him out of high school.
The 2011 MLB Draft came. The Atlanta Braves selected him 28th overall—the first round.
With that pick came a signing bonus of $1.134 million. A life-changing amount of money for a 21-year-old pitcher from California.
That bonus was the foundation of Sean Gilmartin net worth.
The Dependable Reliever Who Pitched In A World Series
Sean Gilmartin’s MLB career was never flashy. He was never the ace. Never the face of a franchise. Never the pitcher fans paid to see.
But he was dependable. He showed up. He pitched in big moments.
His major league debut came on April 10, 2015—against the Atlanta Braves, the very team that had originally drafted him out of high school. Full circle.
In his first MLB season with the New York Mets, he appeared in 50 games, compiled a 3-2 record with a 2.67 ERA, pitched 57⅓ innings, and struck out 54 batters. Solid numbers for a first-year reliever.
Then came 2015’s postseason. The Mets made an improbable run to the World Series. Sean Gilmartin was added to the postseason roster. In Game 2 of the World Series against the Kansas City Royals, he got in the game. He pitched in a World Series game.
Not every pitcher gets to say that.
The Career of Consistent Contracts, Not Superstar Deals
Over his MLB career from 2015 to 2020, Sean Gilmartin never signed a blockbuster contract. He never got a long-term deal worth tens of millions. He earned steady salaries with the Mets ($507,500 in 2015, $517,500 in 2016) and moved between teams as a reliable relief arm.
The St. Louis Cardinals signed him. The Baltimore Orioles signed him. The Tampa Bay Rays signed him. Each team valued his consistency. His left-handed pitching. His ability to get outs in pressure situations.
His career statistics—81 appearances, 112 innings pitched, 90 strikeouts, 4.34 ERA—tell the story of a dependable middle reliever. Not spectacular. But real.
By 2020, his final MLB game came on August 22 against the Toronto Blue Jays. At age 30, his time in the major leagues ended.
The Financial Reality of A Non-Superstar Career
Here’s where Sean Gilmartin net worth becomes instructive. He never made the kind of money elite pitchers earn. He didn’t sign for $100 million. He didn’t get endorsement deals worth millions. He wasn’t a household name.
But he was paid to play professional baseball for a decade. And he managed his money carefully.
His estimated total career earnings from MLB contracts are around $3.5 million. Add his $1.134 million signing bonus. Add minor league contracts and minor league earnings from 2012-2014 ($150,000-$250,000 estimated).
Then subtract: agent fees (typically 4-5%), federal and state taxes (roughly 35-40%), living expenses, relocation costs.
What remains is Sean Gilmartin net worth: $3-5 million.
Not spectacular by baseball standards. But real. Genuine. Built through consistent income and disciplined financial management.
