Red Sox promote relief prospect Caleb Bolden to Double-A Portland

The Red Sox have promoted relief prospect Caleb Bolden from High-A Greenville to Double-A Portland, according to the club’s MiLB.com transactions log.

Bolden has enjoyed a strong start to the 2024 season with Greenville. The 25-year-old right-hander has allowed just two unearned runs on six hits and six walks to go along with 20 strikeouts over eight appearances (13 innings) for the Drive in which he has held opposing hitters to a .136 batting average against. He has also gone 3-for-3 in save opportunities.

Bolden was originally selected by the Red Sox in the seventh round of the 2022 amateur draft out of TCU. As a graduate transfer who previously spent four years at Arkansas, the Texas native received a modest $7,500 signing bonus from Boston and made his professional debut in the Florida Complex League.

Since then, Bolden has compiled a 3.84 ERA and 3.23 FIP with 104 strikeouts to 37 walks over 42 relief outings (72 2/3 innings) at three different minor-league levels. The 6-foot-2, 190-pound hurler throws from a three-quarters arm slot and incorporates a high leg kick into his delivery. He operates with a three-pitch mix that consists of a 92-94 mph fastball that tops out at 95 mph, an 80-82 mph sweeping slider, and an 83-85 mph changeup, per his SoxProspects.com scouting report.
