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.
Lit up again Saturday
Parker (7-14) took the loss Saturday, coughing up six runs on six hits and a walk over five innings as the Nationals were downed 6-4 by the Phillies. He struck out three.
Analysis
The left-hander kept Philly off the board for three innings before crumbling, and he got the hook after 103 pitches (68 strikes). Parker was hit hard once again, as four of the six hits he gave up went for extra bases, including homers by Edmundo Sosa and Trea Turner. Parker is 0-4 over his last five starts, a stretch in which he's produced a 12.00 ERA, 1.95 WHIP, 3.0 HR/9 and 13:11 K:BB over 21 innings. Despite those ghastly numbers, the Nats haven't provided any hints that his rotation spot is in jeopardy. He'll try to turn things around in his next outing, which lines up to come at home next weekend against the Rays.

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.
