25-Year-Old PitcherSP
2021 Fantasy Outlook
Marcus Stroman's injury paved the way for Peterson's early promotion from the Mets' alternate training site. He remained in the rotation all year, save for a 10-day stint on the IL with shoulder inflammation and a brief trip to the bullpen. Peterson appeared in 10 games, starting nine while supplying the Mets with much-needed innings. While his 3.44 ERA appears impressive, his 5.26 xFIP and 5.11 SIERA disagree. Peterson benefited from a .233 BABIP, which helped to offset a bloated 11.7 BB%. The lefty's strikeouts have been inconsistent, with last season's 19.5% mark being low in today's landscape. Peterson should have an Opening Day spot in the Mets' revamped rotation. His minor-league history portends an improved walk rate, but he'll need to miss more bats to fend off impending ERA correction. Consider Peterson in formats conducive to streaming as Citi Field is the league's best pitching venue. Read Past Outlooks

April 14, 2021
Peterson (1-1) picked up the win Wednesday in a 5-1 victory over the Phillies, giving up one run on two hits over six innings while striking out 10.
ANALYSIS
The young southpaw was in firm control, tying his career high in strikeouts, and he made only one real mistake that Jean Segura launched over the fence in the fifth inning. Peterson threw 57 of 80 pitches for strikes in his first quality start of the year, but after a rough season debut he'll still carry a 6.30 ERA into his next outing, set for April 21 on the road against the Cubs.

Stat Review

* Exit Velocity, Barrels/BBE %, Balls Hit 95+ MPH %, and Spin Rate are benchmarked against 2019 data (min 120 IP). See here for more exit velocity/barrels stats plus an explanation of current limitations with that data set.

Past Fantasy Outlooks
2020
2019
2018
In an era where strikeouts are king, Peterson gets it done the old-fashioned way: command, control and groundballs. That said, if he maintains the punchout gains of the past couple of seasons, Peterson has mid-rotation upside. The southpaw sits around 90 mph with his fastball, touching 93. It has good sinking action, helping to record one of the highest groundball rates in the minors. Peterson's slider is his strikeout pitch while he also works in a changeup and curveball. None are dominant, but he throws each for strikes. Peterson spent 2019 with Double-A Binghamton, posting a 4.19 ERA and 1.34 WHIP, giving up 119 hits in 116 innings while fanning 122 with 37 walks and nine homers. The high WHIP is characteristic of a groundball pitcher and should improve with better infield defense. Peterson should open the season with Triple-A Syracuse and could be a candidate for a callup if the Mets need a starter.
Other than a truly elite groundball rate (over 62% as a pro) and a frame (6-foot-6, 240 pounds) that should allow him to chew up innings, there is not a ton to get excited about with Peterson at first glance. The big lefty commands a four-pitch mix, with his heavy, low-90s fastball and above-average slider grading out as his two best offerings. A knee injury cost him a few weeks early in the year, but he still amassed 128 frames. Over his final five starts, he gave up two runs, allowed 21 baserunners and struck out 32 over 29 innings. His groundball rate was also a ridiculous 71% over that stretch. That success in a small sample might mean nothing. After all, he was a 22-year-old southpaw with command and pitchability facing High-A hitters at the end of a long season. However, if he somehow maintains that late-season strikeout rate at Double-A, it would warrant quick action in dynasty leagues, as his ability to generate weak contact is already outstanding.
A big 6-foot-6 southpaw, Peterson has the potential to have three above-average pitches and and above-average command down the road, hinting at a future role as a No. 4 starter. His low-90s fastball isn't much of a bat-misser, but he should excel at generating groundballs. His slider and changeup both have the potential generate whiffs, and while neither is a plus pitch right now, both have a chance to get there. The key for Peterson will be carrying over the excellent control he showed in his junior season at Oregon, where he posted a 1.4 BB/9. Surgery to remove an ingrown toenail limited him to just three starts for a total of just 3.2 innings in his pro debut. He is advanced enough to head to Low-A or High-A this season. If he were to experience a slight uptick in velocity, Peterson's secondaries and command profile could allow him to project as No. 2 or No. 3 starter, but for now his upside appears capped.
