The Nationals have agreed to a minor-league deal with left-hander Cionel Perez, according to Francys Romero of Beisbol FR. Perez earns an invite to major-league Spring Training. He will earn $1.9MM if he makes the roster, with $700k in incentives, per Jon Heyman of the New York Post. Perez is represented by Octagon.
Perez is an eight-year big-league veteran. After stints with the Astros and Reds from 2018-21, he was claimed off waivers by the Orioles in November 2021 and subsequently earned a larger role. His first season in Baltimore was his best. Perez posted a shiny 1.40 ERA in 57 2/3 innings across 66 appearances in 2022. His expected stats weren’t quite as high on him, though his 3.63 xERA and 2.80 FIP still painted the picture of an above-average reliever. Perez excelled that year by keeping the ball in the park and getting plenty of groundballs. His 51.3% groundball rate was tied for 33rd among 152 qualified relievers that year. His 0.31 HR/9 rate was 11th-best.
Perez’s 2023-24 numbers were more serviceable than great. His strikeout and walk numbers both trended in the wrong direction from 2022, leaving him with a 7.2% K-BB rate. He still excelled at inducing grounders, with a 58.3% groundball rate across those two seasons (including a career-best 60.7% mark in 2023). Altogether, he posted a 4.04 ERA in 107 innings from 2023-24.
Batters teed off on Perez in 2025. In 19 appearances in the season’s first two months, he posted an ERA of 8.31 with an elevated 16.4% walk rate, his highest since 2021 with the Reds. More surprisingly, after allowing just four home runs in total from 2022-24, Perez allowed three in only 21 2/3 innings in 2025. A .379 BABIP and 3.93 xERA suggest he was the victim of bad luck, but his 5.77 FIP implied he was doing poorly independently of his defense. By the end of May, the Orioles had seen enough. Perez was designated off the 40-man roster and spent the rest of the year at Triple-A, pitching to a 6.85 ERA in 22 1/3 innings.
Despite the disappointing end to his Orioles tenure, a look at Perez’s Statcast page gives some reason for optimism. His fastball velocity, expected batting average, barrel rate, and groundball rate all would have ranked in the 71st percentile or better had he pitched enough to qualify. As recently as 2024, Perez’s slurve and sinker were above average pitches by run value. Opponents slugged just .282 and .314 against those pitches, respectively.
For the rebuilding Nats, there is no risk in bringing Perez into the fold of what is otherwise a young, inexperienced bullpen. Julian Fernandez and waiver claim Richard Lovelady are the only projected members with even two years of service time, per RosterResource. At the least, Perez is an experienced lefty with a high groundball rate who could turn into a trade candidate by the deadline if he rebuilds his value. Assuming he makes the roster, his $1.9MM salary would bring the Nationals’ payroll to $95.38MM and their luxury tax payroll to $118.18MM.
