2025 Fantasy Outlook
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. Read Past Outlooks
Signed a one-year contract with the Nationals in March of 2025.
Logs quality start in win
Parker (6-10) earned the win against the Padres on Saturday, allowing two runs on five hits and one walk with four strikeouts over five innings.
Analysis
Parker allowed two runs in the third inning but was otherwise strong despite generating just six whiffs on 82 pitches. It was an encouraging effort after the southpaw surrendered 16 runs (11 earned) over his previous two July outings, and he's now logged two quality-start victories against the Padres since June 23. He'll carry a 5.00 ERA, 1.40 WHIP and 70:41 K:BB across 108 innings into a road matchup with the Twins next weekend.

2024 Fantasy Outlook
A 24-year-old lefty, Parker has been a notable prospect in a shallow Nationals farm system for a couple years, but poor control and middling stuff limited his realistic upside. Parker primarily operates with a 92-mph four-seamer with solid movement and an 80-mph curveball while also mixing in a mid-80s splitter. He walked between 11.1 and 15.4 percent of batters from 2022 through 2023 while pitching in the mid-to-upper minors, and he doesn't have the pure stuff to have success with that many free passes, but only issued one walk in his first two starts of 2024, with one of those coming against the Dodgers' big-league lineup. Assuming Parker spends a good chunk of 2024 in the big-league rotation, he could be a deep-league streamer in good matchups, but there's not much data to suggest he can maintain the success he's had early in the season.
