​While ​Edwin Diaz has been solid throughout much of the season, he seems to be the only reliable option in the ​Mets bullpen. The team's relievers have posted a 5.37 ERA thus far into the year and have not been able to get the job done. 

Diaz is not the problem, but the star closer has surrendered a run in each of his past two outings. If the 25-year-old falls of the rails, the Mets would be in deep trouble, unless of course they are able to bring aboard the best remaining reliever on the open market.

Per reports from Andy Martino, the Mets have holding "continued dialogue" with free agent closer ​Craig Kimbrel

​​Kimbrel is coming off of a strong regular season, albeit a rough postseason, but was unable to come to terms with a team during free agency. Now, one month into the season, Kimbrel remains available despite the handful of teams with woeful bullpen results thus far into the year. 

If the Mets want to rely entirely on Diaz's production in late innings, that's their decision, but when their 25-year-old closer is the only trustworthy options to help carry games to the end, then there's a real problem.

Diaz has a sparkling 2.13 ERA this season, paired with 8 saves and 21 strikeouts in 12.2 innings pitched. Those numbers were even more impressive heading into the Mets' four-game series with the Reds, during which ​Diaz recorded two losses and elevated his ERA from 0.84 to 2.13. 

Kimbrel would be a perfect addition to the bullpen and could immediately step in and act as a setup option before the team deploys Diaz in the ninth inning. 

At this point, Kimbrel would likely consider taking the one-year deal he was so adamant about avoiding on the open market. If he wants to get back into the big leagues in 2019, a short-term contract seems like his best, and maybe only, option.
