The Nationals have signed right-hander Jorge Lopez, according to The Athletic’s Ken Rosenthal. Lopez will receive $3MM in guaranteed money in the one-year contract, the New York Post’s Jon Heyman reports, plus some more money is available in incentives. The Nats have officially announced the signing, and also announced that right-hander Amos Willingham was designated for assignment to create roster space for Lopez.
Lopez, 32 next month, spent the first several years of his big league career as a below-average swingman. He made his big league debut with the Brewers back in 2015, and in parts of six seasons with Milwaukee, Kansas City, and Baltimore he posted a 6.04 ERA (76 ERA+) with a 5.15 FIP in 102 appearances, 58 of which were starts. After posting ERAs north of six in three consecutive seasons as a swingman from 2019 to 2021, the Orioles converted Lopez to short relief full-time ahead of the 2022 season.
From there, his career has taken a major step forward. His breakout began with a sterling 1.68 ERA in the first half while collecting 19 saves as their closer. He was traded to the Twins ahead of that summer’s trade deadline and faded somewhat down the stretch, but still finished the season with an excellent 2.54 ERA (155 ERA+) and 3.42 FIP in 71 innings of work. While his 10.4% walk rate left something to be desired, he combined it with a solid 24.2% strikeout rate and a fantastic 57.8% groundball rate, giving him strong peripherals that suggested he could have a future in the late innings.
Unfortunately, Lopez was unable to recreate that excellent 2022 season the following year. He took a massive step back in 2023 while spending time on the injured list for mental health reasons, and when he was on the mound he pitched to a 5.95 ERA in 59 innings of work. Nonetheless, Lopez managed to latch on with the Mets last year on a big league deal. His tenure in Queens was brief, as while he posted decent middle relief numbers (including a 3.76 ERA in 26 1/3 innings of work) he was designated for assignment in late May following a controversy regarding a post-game interview where he seemingly referred to the Mets as the “worst team” in the league, though in the aftermath of the incident it appeared that Lopez had actually referred to himself as the “worst teammate” in the league.
That rocky exit from the Mets in, in conjunction with his difficult 2023 season, left Lopez to catch on with the Cubs on a minor league deal. He made the most of the opportunity, however, and looked every bit like the dominant late-inning arm he had been for the Orioles in 2022. In 26 2/3 innings of work for Chicago last year, Lopez posted an excellent 2.03 ERA. He struck out 29.2% of his opponents during that stretch with a walk rate of just 7.5%, and his 59.1% groundball rate was nothing short of elite. Taking that fantastic work on the north side together with his time in Queens paints a picture of Lopez as an intriguing, if somewhat risky, late-inning option as he posted a 2.89 ERA and 3.94 FIP in 53 innings of work with a 23% strikeout rate and 51% groundball rate.
Lopez is now headed to the Nationals, where he appears likely to be tasked with the closer role barring another external addition. That role had belonged to Kyle Finnegan in recent years, but the club non-tendered him back in November due to his rapidly escalating price in arbitration. Finnegan was projected by MLBTR contributor Matt Swartz for an $8.6MM salary in 2025, and Lopez is signing in D.C. for just over a third of that amount after posting better rate numbers than Finnegan did in 2024.
The addition of Lopez brings the Nationals’ payroll up to a projected $110MM for 2025 according to RosterResource. That’s $20MM below the club’s 2024 payroll, meaning they should have room for further upgrades to the roster should opportunities arise in trade or on the free agent market. That said, it’s already been a fairly busy winter for the Nationals. Lopez joins rotation additions Trevor Williams and Michael Soroka on the pitching staff, while Josh Bell and Nathaniel Lowe were brought in to bolster the club’s lineup. There’s still room for improvement, however, particularly in the bullpen and at third base.
As for Willingham, the right-hander has been and up-and-down reliever for the Nationals over the past two seasons. To this point in his career, he’s posted a 7.11 ERA in 25 1/3 innings of work at the major league level with just one appearance for Washington in 2024. He posted a decent 3.69 ERA for Triple-A Rochester last year, however, and it’s not impossible to imagine a rival club having some interest in Willingham as optionable relief depth. Going forward, the Nationals will have one week to either work out a trade involving the right-hander or try to put him through waivers. If he clears waivers unclaimed, the Nationals will have the opportunity to outright him to the minor leagues as a non-roster depth option.
