The Red Sox continue to tweak their pitching staff, in the midst of having allowed at least five runs in seven of their last eight games. This time, they’re bringing in an external option.

On Monday, the team acquired relief pitcher Yacksel Rios from the Seattle Mariners in exchange for cash considerations. Rios was DFA’ed by the Mariners on June 11.

So far this season Rios has appeared in three major league games, allowing three earned runs in three innings. In 12 minor league outings this year, the righty has a 1.32 ERA and 0.73 WHIP over 13.2 innings.
