With Baseball America‘s Adam Rubin reporting the Mets are considering using low A starter P.J. Conlon out of the bullpen, the Mets are really giving the impression that they may not sign any relief pitchers this offseason. This would coincide with earlier reports the Mets may not have the budget to acquire another player unless the team is able to trade an outfielder, namely Jay Bruce. When considering the difficulties the Mets have in trading Bruce, it’s becoming increasingly more likely the Mets will use internal options to build their bullpen.

The Mets should have varying degrees of confidence in returning relief pitchers Jeurys Familia, Addison Reed, and Hansel Robles. Last season, Reed and Familia combined to be the best 8-9 combination in baseball. Robles has shown versatility whether it was his bailing Jim Henderson out of a bases loaded no out jam or pitching 3.2 innings because Bartolo Colon left a game in the first inning with an injury.

While the Mets should have confidence in these three pitchers, they still need at least four other arms to complete their bullpen. Here are the leading options:

RIGHT-HANDED RELIEVERS

RHP Seth Lugo – While he should get the opportunity to compete with Robert Gsellman for a spot in the rotation, indications are Lugo will land in the bullpen. In limited bullpen duty last year, Lugo was terrific. In his nine relief appearances, he had a 2.65 ERA, 0.941 WHIP, and an 8.5 K/9. Pitching out of the bullpen should also permit Lugo to ramp his fastball up to 95 MPH and throw his curveball, which has the best spin rate in the majors, making him an even more dominant pitcher.

RHP Zack Wheeler – Like Lugo, Wheeler may get an opportunity to pitch in the rotation, but early indications are he will start the year in the bullpen. Wheeler’s fastball-slider combination should play well out of the bullpen, and it should lead to him recording a high number of strikeouts. Conversely, he may have a high amount of walks as well. Unfortunately, Wheeler may not be able to sustain the same workload of a relief pitcher as the Mets will likely want to ease him back after Wheeler missed two years due to Tommy John surgery.

RHP Paul Sewald – With a high 80s to low 90s fastball with a slider in the low 90s with a low 80s slider, Sewald doesn’t have the dominating stuff you would typically look for in a major league reliever. However, despite having “lesser” stuff, Sewald has succeeded at every level of the minor leagues including his being an effective closer for the 51s last year. Despite pitching in an extreme hitter’s league, Sewald had 10 saves with a 1.85 ERA, 0.945 WHIP, and an 11.8 K/9 in the second half of the season.

RHP Erik Goeddel – If Goeddel can return to his 2014 – 2015 form, the Mets have a reliever they can rely upon. During that time, he was on the New York – Las Vegas shuttle making 41 major league appearances. Over that stretch, he had a 2.48 ERA, 1.000 WHIP, and a 9.0 K/9. For many, it was believed Goeddel did it with smoke and mirrors, an impression that was given credence with his 4.54 ERA and 1.318 WHIP in 2016. With Goeddel able to strike out 9.1 batters per nine last year, he has at least shown he can get batters out, and as a result, should get another chance. His success in 2017 is going to depend on his ability to regain some of his fastball velocity or his ability to adapt to pitching without it.

RHP Chase Bradford – Like Sewald, Bradford has fringy stuff with a low 90s fastball and a low to mid 80s slider. However, unlike Sewald, Bradford has struggled in AAA. Over the past three years, Bradford has pitched to a 4.88 ERA, 1.454 WHIP, and a 7.2 K/9. It should be noted many pitchers, like Lugo, struggle in Las Vegas, only to have success in the majors.

RHP Ben Rowen – The submarine style Rowen was brought in on a minor league deal with an invitation to Spring Training. The hope is that Rowen can be a modern version of Chad Bradford in what was an excellent 2006 Mets bullpen. However, given his low 80s fastball, and with both right-handed batters and left-handed batters hitting him hard in his brief 12 major league appearances, this seems more hope than reality.

RHP Rafael Montero – Despite being terrible for the Mets, he somehow remains a part of the Mets organization. As if his presence on the roster wasn’t baffling enough, Sandy Alderson even mentioned him as a possibility for the bullpen. (ESPN). It figures that this year is the year push comes to shove with Montero. Either he is finally going to trust his stuff and throw strikes at the major league level, or the Mets are going to designate him for assignment for someone who can.

RHP Gabriel Ynoa – Ynoa struggled with the Mets last year, but those struggles could have been the result of him being asked to pitch out of the bullpen when he’s never done that before and the team shifting him between the bullpen and rotation late in the year. Fact is Ynoa has real talent. He has a low to mid 90s fastball that he may be able to consistently get in the mid 90s if he was airing it out in the bullpen. His slider is also effective in generating a number of groundballs. With him in the bullpen as opposed to the rotation, he can primarily utilize his two best pitches to get batters out.

LEFT-HANDED RELIEVERS

LHP Josh Smoker – There are three things we learned about Smoker last year: (1) he strikes out a lot of batters; (2) left-handed batters absolutely crush him; and (3) he is not effective for more than one inning. Now, if Smoker is able to work with Dan Warthen to develop a slider to get help him get left-handed batters out, he’s got closer potential. If not, he’s still an effective arm out of the bullpen so long as Terry Collins acknowledges his limitations.

LHP Josh Edgin – Even with his reduced velocity, Edgin still showed the ability to get left-handed batters out. Until such time he re-gains his velocity, if it ever were to happen, he should primarily be used as a LOOGY. Now, with Familia, Reed, and Robles each being extremely effective against left-handed batters, the Mets are not in dire need of a LOOGY. Still, in a division with Freddie Freeman, Daniel Murphy, and Bryce Harper the Mets could benefit from having more than one pitcher who can get left-handed batters out.

LHP Sean Gilmartin – In 2015, Gilmartin was an important part of the Mets bullpen as the team’s long man. That season, he made 50 appearance pitching 57.1 innings going 3-2 with a 2.67 ERA, 1.186 WHIP, and an 8.5 K/9. Surprisingly, Gilmartin had reverse splits allowing a .216 batting average to right-handed batters and a .260 batting average to left-handed batters. Last, year, Gilmartin began the year in Las Vegas as a starting pitcher. Due to some bullpen issues at the major league level, the Mets had him fly on a red eye and pitch on short rest. Eventually, he would suffer a minor shoulder injury, and his promising season would tail off. Ultimately, the Mets will need a long man in 2017, and there is enough evidence here to suggest Gilmartin can competently fill that roll.

LHP David Roseboom – It’s not common for pitchers to go from AA to the Opening Day roster the next year, but Roseboom may just be capable of doing it. While a closer by trade, who is coming off a season with a 1.87 ERA, he is extremely effective against left-handed batters. Last season, he limited left-handed batters to a .141 batting average. Primarily, Roseboom is a sinker/slider pitcher who also has a change that allows him to remain effective against right-handed batters. While Roseboom primarily sits in the high 80s to the low 90s, he remains effective because he is able to effectively locate his pitches, and he induces a high rate of ground balls.

LHP P.J. Conlon – As touched on above, considering Conlon for the Opening Day roster was a surprise given he has not pitched in AA, he consistently throws in the mid to high 80s, and he was used as a starter last season. Another reason this was a surprise is the Conlon is better against right-handed batters than left-handed batters. The main reason for that is while Conlon is a four pitch pitcher, his out pitch is his change-up. Like with most left-handed pitchers, Conlon’s change-up is more effective against right-handed batters than left. Overall, it is highly unlikely he will make the Opening Day roster, but he should still benefit from the opportunity to further develop his slider.

PREDICTION

Barring unforeseen circumstances, Wheeler seems assured of being in the Opening Day bullpen with Familia, Reed, and Robles. Considering the Mets probably want to add another left-handed pitcher in the bullpen, and the fact that he is out of options, Edgin seems to be the next best guess as to a pitcher who will make the r0ster. Based upon their performance in the bullpen last year, it is likely the next two spots go to Lugo and Smoker. Right there, the Mets have a seven man bullpen with an interesting array of arms that can both register strike outs and induce ground balls to try to get a double play to get out of the inning.

If there is an injury, suspension, or someone proves to be ineffective, the Mets have interesting options behind this group in Rowen, Sewald, and Roseboom. There is also Gilmartin and Ynoa who can provide either a spot start or be able to serve in the bullpen if needed.

Ultimately, while you would feel much better with the Mets having at least one more veteran arm in the bullpen like a Jerry Blevins or a Fernando Salas, there is at least enough quality arms in the Mets system that can conceivably build a good bullpen.
