The New York Mets have emerged as the most active team so far this winter as they look to move on from a disappointing playoff miss and re-ignite World Series championship expectations.
Two weeks ago, the team swapped long-tenured outfielder Brandon Nimmo to the Texas Rangers in exchange for second baseman Marcus Semien. And on Monday, news surfaced that the team had agreed to bring in former New York Yankees reliever Devin Williams with a three-year, $51 million contract.
Williams struggled with the Yankees in this past season, but he is a two-time National League Reliever of the Year Award winner and, if he returns to that form, his contract will be a steal for the Mets. But the addition instantly raised questions about what the Mets might be planning to do next, with their reigning All-Star closer Edwin Diaz still out on the open market.
“Williams chose the Mets on Monday night, not knowing whether he would be used as an ace setup option ahead of Edwin Diaz or as a closer replacing Diaz,” Will Sammon reported for The Athletic. “They remain open to a reunion with Diaz, formerly their star closer and the best reliever available in free agency, league sources said. So, Williams may pitch the ninth inning, but he also may end up pitching the eighth inning instead.”
There seems to be little question that Diaz is the more trustworthy of the two options to close out critical games. While Williams had some strong moments in the Bronx, he seemed to struggle when the pressure was highest. That would make him a strong setup man for a closer like Diaz, though Diaz won’t be easy to re-sign.
“There are multiple teams seriously interested in Diaz, 31, people familiar with his market said,” Sammon added. “Throughout negotiations between Diaz and the Mets, contract length emerged as a sticking point…”
While there is still much to be determined about the Mets’ bullpen construction, Williams has reportedly already sent the team a message about how he would feel deferring to Diaz as the team’s returning closer.
“Of note, multiple sources said the Mets still have interest in re-signing incumbent closer Edwin Diaz even after agreeing to terms with Williams,” Anthony DiComo reported for MLB.com. “The latter is comfortable serving in a setup role if the Mets do retain Diaz, according to one of those sources.”
With Williams willing to play either a closer or setup role for the Mets, it seems the team’s options remain open for this winter. And that could be a sign that more surprising moves are to come.
