The Arizona Diamondbacks claimed left-handed reliever Joe Jacques off waivers from the Boston Red Sox on Tuesday.
Boston designated Jacques for assignment Friday to make room on the 40-man roster for 31-year-old rookie Cam Booser.
The Red Sox now have four lefty relievers — Booser, Joely RodrÃguez, Brennan Bernardino and Brandon Walter — on the 40-man roster. Booser, RodrÃguez and Bernardino are all on the active roster. Walter is on Triple-A Worcester’s IL with a rotator cuff strain. Lefty reliever Chris Murphy is on the 60-day IL (and out for the season) after undergoing Tommy John surgery.
