The Washington Nationals have signed veteran right-hander Miles Mikolas to a one-year deal, aiming to strengthen a rotation facing significant inexperience and uncertainty. The agreement was officially announced recently after discussions earlier in the week, with Mikolas expected to bring stability as the Nationals prepare for the upcoming season.
Contract Details and Roster Moves
Miles Mikolas will receive a base salary of $2.25 million, with additional performance incentives that could increase the total value, according to Jon Heyman of the New York Post. To accommodate Mikolas on the 40-man roster, the Nationals placed pitcher DJ Herz on the 60-day injured list following his Tommy John surgery last April, opening the necessary spot for the veteran right-hander.
Mikolas’s Career Journey and Recent Performance
At 37 years old, Mikolas has solidified himself as a reliable starting pitcher in recent years. He began his major league career with the Padres and Rangers before spending three years in Japan’s NPB with the Yomiuri Giants. Returning to MLB in the 2017-18 offseason, Mikolas signed with the St. Louis Cardinals, where he made 32 starts in back-to-back seasons. Although forearm injuries sidelined him during parts of 2020 and 2021, he has since been a regular in the rotation. From 2022 onward, Mikolas has started at least 31 games each season, including a league-high 35 starts in 2023. Over the last four seasons, only Logan Webb has made more starts than him, with just a few pitchers surpassing his innings pitched.
Declining Effectiveness Despite Durability
Despite his durability, Mikolas’s effectiveness has dropped as his velocity and overall pitching arsenal have diminished. In 2025, he posted a 4.84 ERA and a similar 4.83 SIERA, reflective of struggles on the mound. His strikeout rate and strikeout-to-walk ratio fell to career lows since prior to his time in Japan, registering at 14.9% and 2.70 respectively. Among pitchers throwing at least 150 innings last season, only his new teammate Mitchell Parker had a lower strikeout rate. Mikolas also ranked in the lowest 9% among MLB pitchers for barrels allowed and displayed some of the poorest raw stuff metrics according to advanced models like Stuff+ and PitchingBot.
Importance to Nationals’ Rotation Stability
Despite these challenges, Mikolas’s ability to log innings remains valuable. He threw over 156 innings in 2025 with eight quality starts and consistently pitched at least five innings in nearly all appearances. The Nationals’ starting rotation is young and largely unproven, featuring arms such as Josiah Gray, Cade Cavalli, Foster Griffin, Jake Irvin, Brad Lord, and Mitchell Parker. Among this group, only Irvin and Parker have completed even one qualifying major league season, while Gray is the sole pitcher with a 30-start season. With injury concerns and inconsistency common among these starters, Mikolas’s experience offers an important safety net to boost the reliability of a struggling pitching staff.

Outlook for the Nationals’ Season Ahead
By adding Miles Mikolas, the Nationals aim to shore up their rotation depth with a known quantity who can handle a heavy workload. His veteran presence and durability could alleviate some pressure from a younger pitching corps that still needs to prove it can produce consistent results. While his declining raw ability raises concerns about effectiveness, his role as an innings eater makes Mikolas a key piece for a Nationals team looking to find stability in a challenging season.
