Peters was a top prospect as a prep pitcher, but he decided to go to Texas.  His velocity actually dropped while he was in college, from 93-94 mph to 88-92.  He remained a good prospect because of his command of the fastball and an average curve and change.  He injured his elbow during his junior year and had Tommy John surgery before the draft, but the Marlins picked him in the tenth round knowing he’d be unavailable for a year.  His velocity picked up again after he recovered, but during his time in the majors he’s thrown just a little above 90.  Peters succeeded in the low minors despite low K rates due to excellent control.  He’s had a rough time, though, above AA.


Peters didn’t pitch following the Tommy John surgery.

R:  1-1-0, 0.68 ERA, 0.98 WHIP, 13.1 IP, 2.0 BB/9, 8.8 K/9
A-:  0-3-0, 4.83 ERA, 1.58 WHIP, 31.2 IP, 2.8 BB/9, 7.7 K/9

After he pitched a little in rookie ball, the Marlins sent Peters to the New York-Penn League.  He got hit hard there, but that may have been the aftermath of the surgery.

A+:  11-6-0, 2.46 ERA, 1.11 WHIP, 106.0 IP, 1.4 BB/9, 7.6 K/9
AA:  3-0-0, 1.99 ERA, 0.93 WHIP, 22.2 IP, 1.6 BB/9, 6.4 K/9

Peters had an impressive season, mostly in high A but finishing with four starts in AA.  He allowed only six home runs and rarely walked anybody, although his K rate wasn’t impressive.  Baseball America rated him the fifth best prospect in the Marlins’ system.

R:  0-1-0, 1.35 ERA, 1.05 WHIP, 6.2 IP, 5.4 BB/9, 8.1 K/9
A+:  1-0-0, 0.00 ERA, 0.66 WHIP, 10.2 IP, 1.7 BB/9, 7.6 K/9
AA:  6-2-0, 1.97 ERA, 0.96 WHIP, 45.2 IP, 2.2 BB/9, 7.9 K/9
MLB:  1-2-0, 5.17 ERA, 1.63 WHIP, 31.1 IP, 5.5 BB/9, 7.8 K/9

Peters was out for two and a half months, but when he got back to AA he continued to pitch very well.  The Marlins called him up for September and he made six starts for them.  After seldom walking anybody in the minors, he had control problems in the majors, which often happens with finesse pitchers who rely on getting hitters to chase their pitches.  BA ranked him 11th in the Miami system.

AAA:  6-7-0, 5.61 ERA, 1.54 WHIP, 102.2 IP, 2.5 BB/9, 7.5 K/9
MLB:  2-2-0, 7.16 ERA, 1.77 WHIP, 27.2 IP, 4.9 BB/9, 5.5 K/9

Peters opened the season in the Marlins’ rotation and struggled.  Miami sent him to AAA in early May and he spent the rest of the year there, except for one start for the Marlins.  He struggled in AAA as well.  After the season, Miami designated Peters for assignment and then traded him to the Angels.

AAA:  4-1-0, 6.47 ERA, 1.60 WHIP, 57.0 IP, 2.7 BB/9, 8.7 K/9
MLB:  4-4-0, 5.38 ERA, 1.54 WHIP, 72.0 IP, 3.3 BB/9, 6.9 K/9

Peters was up and down several times, dividing his time between AAA and the majors.  He didn’t pitch well at either level, although pitching at Salt Lake City in the Pacific Coast League undoubtedly inflated his numbers.  He had gopher ball problems at both levels.

MLB:  0-0-0, 16.20 ERA, 1.80 WHIP, 1.2 IP, 0.0 BB/9, 10.8 K/9

Peters was on the injured list with an oblique strain at the start of the delayed season.  He wasn’t activated until September and got into only one game with the Angels.  They outrighted him to AAA after the season.

AAA (LAA):  2-2-0, 4.35 ERA, 1.45 WHIP, 41.1 IP, 2.8 BB/9, 10.5 K/9

Opening the season in AAA, Peters had a sharply increased K rate.  His ERA seemed high, but again he was at Salt Lake City.  The PCL ERA while he was there was 5.63 and the team’s ERA was 5.66.  Peters did, however, have a major problem with homers, giving up one every three and a half innings.  The Angels designated him for assignment in mid-July and then sent him to the Pirates for cash.

The Pirates probably acquired Peters to bolster their starting depth.  Wil Crowe, Chase De Jong and Cody Ponce had all pitched poorly up to that point in the year.  There was also the chance of Tyler Anderson being traded.  The sudden increase in Peters’ K rate in AAA in 2021 makes him a little more interesting, but there isn’t a lot in his history to suggest he’ll succeed now.
