Nationals Have One Bullpen Problem They Cant Ignore This Winter

As the Washington Nationals aim to revitalize their bullpen, securing top left-handed relievers like Vesia, Romero, and Minter becomes crucial to overcoming recent struggles and setting a competitive tone for the upcoming season.

The Nationals’ bullpen mess has reached the point where Washington can’t afford to treat the problem like a patch job anymore. After finishing 2025 with the worst bullpen ERA in Major League Baseball, the club followed that up by setting the MLB record for the most blown saves in a single season in 2026. That kind of collapse makes one thing obvious: president of baseball operations Paul Toboni has to commit real resources to the relief corps ahead of the 2027 campaign.

One of the biggest holes sits on the left side. Washington’s left-handed relievers posted a 4.94 ERA, which ranked 28th in baseball.

They also tied for the most losses at 15, and their minus-1.1 fWAR was the worst in the majors. So if the Nationals are going to rebuild this group, the free-agent market needs to be a serious hunting ground.

A.J. Minter fits that search as a familiar name with a long track record in the NL East before the New York Mets dealt him to the Minnesota Twins ahead of the 2026 trade deadline.

Over 10 years in The Show, Minter has logged a 3.15 ERA in 445 appearances and 405 1/3 innings pitched. His strikeout rate dipped to 22% this past season, just below the league average of 22.5%, but his career profile still points to a pitcher who misses bats thanks in large part to elite Stuff+ numbers.

The 33-year-old finished 2026 with a 2.56 ERA and an ERA+ of 164 across 48 appearances, even with the strikeout dip. He also did a strong job keeping hitters off base via the walk, with a 4.3% walk rate.

Spotrac pegs his market value at $7.4 million per year and projects a one-year deal. If that’s the price, Washington should be in the mix.

And if the Nationals are willing to go longer than that, it could give them an edge.

JoJo Romero looks like another name that belongs near the top of the board. Since the start of the 2023 season, he has been one of the better left-handed relievers in baseball, putting up a 3.04 ERA over 213 innings after being traded to the St.

Louis Cardinals in the middle of the 2022 campaign. He has 202 strikeouts against 73 walks in that stretch, and his ERA+ sits 40 points above the league average mark of 100.

He’s also been above average in Stuff+ metrics in each of the past four years, which only adds to the appeal.

Romero is 30, so the age profile works in his favor. Spotrac values him at about $6.7 million per year and projects a four-year, $26.7 million deal.

That kind of contract suggests a market that could move quickly, and the Nationals may have competition if they try to get involved. Even so, he’s the kind of high-leverage arm Washington should absolutely chase, even if he hasn’t been a true closer.

If there’s a clear No. 1 target among left-handed relievers, it’s Alex Vesia. The Dodgers have leaned on him heavily, and he’s rewarded them with a 2.66 ERA across 367 appearances over the past six seasons. As a two-time World Series winner, Vesia has also piled up 438 strikeouts and 150 walks in 328 innings, with an ERA+ of 156, which is one-and-a-half times the league average mark of 100.

The fit is obvious, but the price tag won’t be simple. Spotrac puts the 30-year-old at $7.1 million per season and projects a two-year, $14.2 million contract.

Given what he’s done, though, he could draw even more attention than that and end up with a much bigger deal. That would make him tough to land, especially with Washington needing to fill other holes too.

Even so, Vesia should sit at the very top of the Nationals’ wish list. Minter and Romero should be right there as well. If Washington is serious about fixing this bullpen, Toboni and his front office need to be aggressive on all three.

Nationals Fans Should Watch This New C.J. Abrams Buzz Closely

C.J. Abrams has become one of the more interesting names to watch as the offseason chatter starts to build, and for Nationals fans, any buzz around his future is worth tracking closely. The Red Sox are looking at ways to fix a lineup that never really found its footing this year, even with strong starting pitching carrying much of the load, and that has pushed shortstop help toward the top of their list.

Bostons season unraveled early, leading to a managerial change and a long stretch of frustration on offense, with injuries and underperformance from key players adding to the problem. Abrams would fit the kind of upgrade the Red Sox are clearly seeking, which is why this developing free-agent discussion matters beyond just one market. For Washington, it is another reminder that a young, prominent piece can quickly become part of a much bigger winter conversation. [Read more 🡒]

Nationals Bullpen Churn Raises Another Question Fans Know Too Well

The Nationals bullpen shuffle kept moving this week with the release of right-hander Zak Kent, who had been designated for assignment last week. Kents time in Washington came in multiple stops over the course of the season, and he is now a free agent after another short-lived run with the club.

Kents numbers with the Nationals never gave the front office much reason to hold on, as he posted a 5.68 ERA in 12 2/3 innings and had similar trouble at Triple-A Rochester. For a bullpen that has been in constant flux, it is another reminder that Washington is still searching for reliable depth, and still trying to sort out which arms can stick. [Read more 🡒]

Nationals Just Reshaped A Troubling Part Of Their Pitching Depth

The Salt River Rafters found a way to turn a 6-0 lead into an 11-10 loss in 10 innings, and three Nationals prospects were part of the action in a game that had plenty of twists before it finally slipped away. Kevin Bazzell, Teo Banks and Noah Dean all contributed in different ways, giving Washington another look at some of the younger arms and bats that are trying to carve out roles in the organization.

Closer to home, the Nationals also moved to reshape a pitching group that had become a concern. The club officially outrighted and elected free agency for three left-handed pitchers while claiming two pitchers off waivers, a round of roster churn that underscores how much work remains in sorting out the depth behind the big league staff.
