Rest-of-Season Projections
2026 Fantasy Outlook
Parker got off to a flying start in 2025, posting a 1.39 ERA in 32.1 innings across his first five starts of the season. Those good feelings were short lived, as he went on to log a 5-15 record over his next 25 starts while sporting a 7.00 ERA and 1.60 WHIP over 126 innings, which prompted the Nationals to move the southpaw to the bullpen in September. Parker's role in 2026 is unclear, and given that he ranked near the bottom of qualified pitchers in xBA, xERA and strikeout rate, he would provide limited fantasy value even if he were a part of Washington's rotation by Opening Day.

Signed a one-year contract with the Nationals in March of 2026.
Collects multi-inning save
Parker gave up two runs on three hits and a walk over three relief innings Tuesday to record his first save of the season in a win over the Guardians. He struck out five.
Analysis
The 26-year-old southpaw actually fulfilled two separate requirements for a save, as he entered the game with the Nationals ahead 4-1 and stayed in the game the rest of the way after they tacked on a couple insurance runs in the top of the ninth. Parker has worked more than one inning in five of seven May appearances, posting a 5.74 ERA, 1.09 WHIP and 15:4 K:BB through 15.2 innings with two holds in addition to Tuesday's save, but a lack of reliable bullpen options for Washington could keep him in the high-leverage mix.

Past Fantasy Outlooks
2025
2024
Parker beat the eventual world champion Dodgers in his big-league debut in April, and while there were bumps in the road from there, his final numbers as a rookie were highly respectable. The left-hander made 29 starts and totaled 151 innings for the Nationals, pitching to a 4.29 ERA and 1.30 WHIP. HIs fastball is lacking and can get touched up, but his splitter and slider both had whiff rates over 35 percent last season, hinting at room for growth with his strikeout rate even with his below-average velocity. He had a nine-run disaster Aug. 15 at Philadelphia which should serve as a reminder of his downside in the wrong matchup. Eventually he could shed the streamer label, but at least for now Parker should be deployed judiciously, if rostered.
