With the Mets protecting Andres Gimenez, Jordan Humphreys, Ali Sanchez, and Thomas Szapucki from the Rule 5 Draft, the 40 man roster is completely full. With the Mets needing to address a number of areas of this team, this means ever trade, waiver claim, and free agent signing is going to require a player coming off the 40 man roster.

Obviously, Drew Gagnon was the first casualty, but he is not going to be the last. Here is a look at some of the other players sitting on the bubble:

Tyler Bashlor

2019 MLB Stats: 0-3, 6.95 ERA, 24 G, 22.0 IP, 1.727 WHIP, 7.0 BB/9, 8.2 K/9

The success Bashlor has had in the minors has not translated at all to the majors. In fact, his control issues have only been magnified, and he has not been able to blow his fastball by anyone. This left him hittable, and he has been hit hard.

Sam Haggerty

2019 Stats: 11 G, 4 PA, 0 H, 0 BB, 3 K

Haggerty was a September call-up with the Mets looking to add some late game speed as they were making a push for the Wild Card. With the current roster crunch, the Mets are too heavy on infielders. With Luis Guillorme firmly establishing himself as a Major League caliber utility player, Haggerty’s spot is all the more tenuous, and he’s very likely the first position player designated for assignment in the event a non-catcher is signed.

Chris Flexen

2019 Stats: 0-3, 6.59 ERA, 9 G, GS, 13.2 IP, 2.049 WHIP, 8.6 BB/9, 6.6 K/9

After struggling as a two pitch starter in his brief Major League appearances, Flexen was finally moved to the bullpen where he had fleeting success. You could argue with his stuff he could succeed next year in a bullpen role, but it’s very possible the Mets don’t see that happening as he was not called up last September. His being out of options may only accelerate a DFA decision.

Franklyn Kilome

2018 MiLB Stats: 4-9, 4.18 ERA, 26 GS, 140.0 IP, 1.343 WHIP, 3.9 BB/9, 8.0 K/9

Kilome is a promising prospect who has control issues and is coming off Tommy John surgery. So far, the Mets have indicated things are going well in his rehab, and he should be ready to pitch early in the 2019 season. That said, if he has a setback, he could be moved off the roster in short order.

Chris Mazza

2019 MLB Stats: 1-1, 5.51 ERA, 9 G, 16.1 IP, 1.592 WHIP, 2.8 BB/9, 6.1 K/9

Mazza was a 29 year old rookie who finally made his debut with the Mets last year. While he was on the September roster, he did not pitch in a meaningful game although he did pick up his first Major League win on the final game of the season.

Tomas Nido

2019 Stats: .191/.231/.316, 5 2B, 4 HR, 14 RBI

Nido got his chance to be a defensive minded back-up, and he worked well with pitchers like Noah Syndergaard. Still, he effectively hit like a pitcher at the plate, and his framing numbers, albeit good, were not at the point where you could justify keeping him in the Majors with the way he hit. With him being out of options, and the Mets looking to upgrade, he has the most tenuous spot on the 4o man roster.

Stephen Nogosek

2019 Stats: 0-1, 10.80 ERA, 7 G, 6.2 IP, 2.100 WHIP, 2.7 BB/9, 8.1 K/9

Nogosek seemed to turn a corner getting his control under wraps in Syracuse, but those issues would resurface in his brief Major League appearances. There is promise in his arm, but his control issues may eventually make him expendable.

Corey Oswalt

2019 Stats: 0-1, 12.15 ERA, 2 G, 6.2 IP, 2.250 WHIP, 8.1 BB/9, 6.8 K/9

Oswalt was added to the 40 man roster to protect him from the Rule 5 Draft after he was the 2017 Eastern League Pitcher of the Year. Since that time, he has struggled, and it was partially the result of how the team left him sitting dormant for stretches and asking him to pitch on very short rest. He also dealt with some nagging injuries last year. In July and August, when he was healthy and finally giving a stretch of starts, he pitched well posting a 1.98 ERA in 10 starts which will probably save his spot on the 40 man roster. Still, with his not getting a September call-up, it’s not a guarantee.

Paul Sewald

2019 Stats: 1-1, 4.58 ERA, 17 G, SV, 19.2 IP, 1.068 WHIP, 1.4 BB/9, 10.1 K/9

Last year, Sewald was designated for assignment, and yet again, despite the odds, he pitched his way back to the Majors. In fact, at the end of the year, he was arguably the most reliable right-handed reliever in the Mets bullpen not named Seth Lugo. He has a low walk rate, good strikeout rate, and had a better FIP than ERA. One thing which may save him is his still having a Major League option remaining.

Daniel Zamora

2019 Stats: 0-1, 5.19 ERA, 17 G, 8.2 IP, 1.731 WHIP, 5.2 BB/9, 8.3 K/9

Zamora is an interesting case. In his career, he has posted reverse splits, but he has a very good K/BB ratio against LHB flashing a wipeout slider. With MLB enacting rules effectively eliminating the LOOGY role, a pitcher like Zamora could actually have increased value, but for that to happen, he needs to harness himself better. Fortunately, he has options remaining.
