Red Sox acquired LHP Tyler Samaniego, RHP Johan Oviedo and C Adonys Guzman from the Pirates for OF Jhostynxon Garcia and RHP Jesus Travieso.

Samaniego heads to Boston just weeks after being added to Pittsburgh’s 40-man roster to shield him from the upcoming Rule 5 Draft. The 26-year-old lefty has yet to pitch above Double-A, but he impressed across four levels last season with a 3.99 ERA and 44/11 K/BB ratio over 38 1/3 innings. He’ll likely open next year in the upper minors and could pitch his way to Fenway Park before season’s end if the command and swing-and-miss stuff continue to trend upward.
