On November 18, the Boston Red Sox did quite a bit of signing, trading and roster shuffling to make room for three pitching prospects they wish to protect from the Rule 5 Draft.
Earlier in the afternoon, Boston traded homegrown reliever Luis Guerrero to the Tampa Bay Rays and designated Josh Winckowski and Nathaniel Lowe for assignment. Less than an hour before the Rule 5 protection deadline, the Red Sox traded lefty reliever Chris Murphy to the Chicago White Sox, first reported by MLB insider Bob Nightengale.
Britt Ghiroli of The Athletic, first reported that the Red Sox received a catcher in exchange for Murphy.
