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% 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 even independent 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.
More to come.
