When you have a magical season like the Mets had in 2015, there are a number of players that step forward to have remarkable seasons.  For the Mets, one of those seasons came from the unlikeliest of sources in Sean Gilmartin.

With the return of Matt Harvey and the signing of Michael Cuddyer, the Mets were letting the baseball world know 2015 was going to be their season.  There was just one small problem.  They never could quite get the LOOGY they needed.  Jerry Blevins was supposed to have that role, but he broke his pitching arm.  Josh Edgin and Jack Leathersich would join him on the disabled list.  The team traded for Alex Torres, but he was a disaster.  That meant the only real lefty they had in the bullpen was Rule 5 pick Gilmartin.

Except, Gilmartin wasn’t a LOOGY.  In essence, Gilmartin was a pitcher.  In fact, prior to joining the Mets, Gilmarting had spent the entirety of his minor league career with the Braves as a starting pitcher.  As a starter, Gilmartin had neutral to almost reverse splits.  To that end, he wasn’t the guy you wanted as the LOOGY.  Still, Gilmartin knew how to pitch, and when he was given the opportunity, he showed that to the Mets.

It took about a month and a half, but Terry Collins finally figured out Gilmartin’s role.  Gilamartin becaume the long man out of the pen.  It may not be the most glamorous of bullpen jobs, but it is of vital importance.  You need a pitcher who can go out there and keep his team in the game.  If there is an injury or a starter that just doesn’t have it, you need the long man to give the team an opportunity to make the comeback.  In extra innings, you need the guy who can go out there and reliably soak up two or even three innings and put up zeros.  Mostly, you need someone reliable who can save the bullpen.

Gilmartin was exception in that role.  During the 2015 season, Gilmartin made 18 multiple inning relief appearances accounting for 37% of his relief appearances.  Beginning on May 20th, which was really when he was made the long man, Gilmartin made 16 multiple inning relief appearances over his final 33 relief appearances of the season.  Essentially, half the time Gilmartin was used for multiple innings about half the time thereby saving the bullpen.  Namely, Gilmartin was saving Jeurys Familia, who Collins used over and over again because he was just about the only guy Collins trusted out there.

In Gilmartin’s multiple inning appearances, he was dominant.  When he pitched multiple innings, he pitched 32.2 innings going 3-1 with a 1.38 ERA, and a 0.704 WHIP.  Perhaps the key to this was the fact Gilmartin grew stronger as he pitched.  He did his best work between pitches 26 – 50 limiting batters to a .161/.235/.194 batting line.

As for a highlight, pick one. There was his first career win.  The Mets found themselves in a rare slugfest after Dillon Gee was bounced after 3.2 innings having allowed eight earned.  Torres wasn’t much better.  Gilmartin was the first pitcher to enter that game to put up multiple scoreless innings.  He stabilized the game, and he put the Mets in position to win.

There was the July 19th 18 inning game against the St. Louis Cardinals.  At that time, the Mets were so inept offensively, you could load the bases with no outs and start the batter with a 3-0 count, and the Mets still couldn’t score a run.  Gilmartin came on in the 14th inning, and he pitched three scoreless to give the Mets a chance to win that game, which they eventually did with two runs in the 18th.

On August 24th, Gilmartin was overshadowed every which was possible.  The Mets were off and running afte rthe team obtained Yoenis Cespedes.  It was David Wright‘s first game since he came off the Disabled List, and he homered in his first at-bat back with the team.  Lost in the shuffle was this was the rare poor start for Jacob deGrom with him being unable to get out of the fourth.  Gilmartin came on and pitched 3.1 scoreless to give the Mets a chance to come back from an early 7-2 deficit.

More than that, Gilmartin got his first career hit and run scored.  His sixth inning single got yet another rally started.  He scored on a Daniel Murphy three run homer, the Mets lead had actually expanded to 12-7.

Ultimately, it was Gilmartin’s August 24th relief appearance that was the essence of what it means to be a long man in the pen.  He not only went out there and saved the bullpen by tossing 3.1 innings, but he also gave his team a chance to win.  It was a tremendous effort that was overlooked because Wright played in his first game in four months, and the Mets overcame a five run deficit to blow out the Phillies.

Initially, Gilmartin was left off the postseason roster, but after Erik Goeddel‘s struggles in the NLDS, the Mets did the right thing and put Gilmartin back on the roster.  He’d make just one appearance pitching 0.2 scoreless in Game Two of the World Series.  Part of the shame of that World Series was there were multiple occasions to bring on Gilmartin.  Instead his role had gone to Bartolo Colon, who just wasn’t as effective in the role as Gilmartin.

After the 2015 season, the Mets wanted to use Gilmartin as a starter.  With a loaded major league rotation, that meant Gilmartin started the year in Vegas.  He was doing well there until the Mets started messing with him.  With the bullpen not having the effective long man that Gilmartin was in 2015, this meant the team had to call him up to the majors on multiple occasions.  This meant Gilmartin would have to fly cross-country, and the Mets would insert him into games despite his not having had full rest.  He’d develop a shoulder injury.  It may not have been enough to need surgery, but Gilmartin was never the same.

Instead of putting Gilmartin in a position to succeed, the Mets messed around with him until the point they felt his was expendable.  For some reason, with this Mets team again needing a Gilmartin in the bullpen, they refused to give him a chance instead going with Josh Smoker and Neil Ramirez and their pair of ERAs over 7.00.

Gilmartin deserved better than this.  He was a good pitcher who had a significant impact on a pennant winning team.  It disappointing the Mets never again put him in a position to succeed.  With that said, getting designated for assignment by the Mets was probably the best thing for his career.  He will once again have an opportunity to be a good major league pitcher.

While the Mets have overlooked his importance, and fans have become frustrated with him, there are those that never forgot what he once meant to this team.  Personally, I will always be grateful for his 2015 season, and I hope him nothing but success.  He’s still a good pitcher, and he should soon remind everyone of that.

Thank  you and good luck Sean Gilmartin.
