The Red Sox are planning to promote pitching prospect Tanner Houck to make his MLB debut on Tuesday against the Marlins, per various reporters (including Jen McCaffrey of the Athletic). Ian Browne of first reported that a Houck call-up was likely. He will need to be added to the 40-man roster before the promotion can become official.

Boston’s 2017 first-round pick (24th overall) out of the University of Missouri, Houck needed to be added to the 40-man this winter regardless in order to protect him from the Rule 5 draft. There’s little to lose for the out-of-contention Red Sox in getting an abbreviated look at Houck in the season’s final couple weeks.

The 24-year-old has seen his stock dip somewhat since draft day, although he’s still regarded as one of the club’s best short-term pitching prospects.
