Triston Casas’s spot on the Red Sox seems to be safe after the team acquired a trio of starting pitchers, but they were willing to let him go for more than just pitching help.
Boston offered Casas along with Masataka Yoshida in a potential deal for Seattle right-handed pitcher Luis Castillo, MLB.com’s Mark Feinsand reported. In addition to trading Casas and Yoshida, the Red Sox also wanted the Mariners to absorb the three years and $55.8 million remaining on Yoshida’s contract, according to Feinsand.
It had been previously reported that the Red Sox pursued Castillo during the week of the Winter Meetings as they were eyeing one of the Mariners’ pitchers.
