After a string of brutal appearances in relief, the Boston Red Sox designated pitcher Jorge Alcala for assignment on August 5.
The St. Louis Cardinals claimed him off waivers on August 7, first reported by Chris Cotillo of MassLive. Former Red Sox chief baseball officer Chaim Bloom must see what Craig Breslow saw when he traded for the righty from the Minnesota Twins on June 11.
The Cardinals had a few vacancies in their bullpen after their trade deadline moves, one of which sent reliever Steven Matz to the Red Sox.
