The Red Sox have designated right-hander Connor Seabold for assignment in order to open a spot on the 40-man roster for right-hander Corey Kluber, per a team announcement.
Seabold’s DFA registers as something of a surprise, as the 26-year-old (27 later this month) is generally regarded as one of the better pitchers in Boston’s system. While he’s certainly older than most “prospects” at this juncture, each of Baseball America (No. 23), MLB.com (No. 21) and FanGraphs (No. 7) ranked Seabold favorably within the Red Sox’ farm as recently as midway through the 2022 season.
Granted, Seabold has been rocked for 25 runs in just 21 1/3 big league innings to this point in his career. However, the right-hander also turned in a strong 3.32 ERA with a 24.7% strikeout rate and an excellent 5.3% walk rate in 86 2/3 innings of Triple-A ball in 2022. That marked the second straight Triple-A season in which he’s pitched to an ERA in the mid-3.00s with average or better strikeout and walk rates.
Seabold, however, has battled injuries throughout his career — including some elbow troubles in 2021 and a forearm strain in 2022. Those recent arm troubles surely played into this decision, even if Seabold finished out the 2022 season in what appeared to be good health. Durability has been a concern that’s been cited on multiple scouting reports for the 6’2″, 190-pound righty. The fact that he’s tossed just 364 innings, between the big leagues and the minors combined, since being drafted in 2017 speaks to those concerns. Even accounting for a half season in his draft year and he lack of minor league games in 2020, that’s a fairly light innings total for a pitcher who’s worked as a starter over the course of four full professional seasons.
Durability concerns notwithstanding, Seabold is a more or less MLB-ready arm with a solid track record in Double-A/Triple-A and with one more minor league option year remaining. That seems likely to generate interest from another club, be it via a trade or waiver claim. The Red Sox will have a week to trade Seabold, pass him through outright waivers or release him.
