Murphy was added to the Red Sox's 40-man roster Tuesday, Chris Cotillo of The Springfield Republican reports.
Murphy is one of Boston's top pitching prospects, and the organization added him to the 40-man roster in order to protect him from the upcoming Rule 5 draft. The 24-year-old split 2022 between Double-A Portland and Triple-A Worcester, and he had a 4.03 ERA, 1.28 WHIP and 149:72 K:BB across 152 innings between the two levels.
