Red Sox acquire right-hander Yacksel Rios from Mariners, add him to 40-man roster

Rios, who turns 28 later this month, will be added to Boston’s 40-man roster after the club designated fellow righty Ryan Weber for assignment to create an opening on its major-league roster for Michael Chavis earlier Monday afternoon.

Per MassLive.com’s Chris Cotillo, “it appears Rios may take Chavis’ active roster spot when he is ready to join the team.”

The 27-year-old hurler allowed an earned run in each of his three appearances out of Seattle’s bullpen this month before he, too, was designated for assignment on June 11 despite having a minor-league option remaining.

A former 12th-round draft pick of the Phillies back in 2011, Rios made his major-league debut for Philadelphia during the 2017 campaign.

Since then, the 6-foot-3 hurler has made a total of 69 appearances in parts of four big-league seasons between the Phillies, Pirates, and Mariners. He owns an ERA of 6.47, a FIP of of 4.82, and a strikeout-to-walk ratio of 70:36 in those outings dating back to August 2017.

After being let go by Pittsburgh over the winter, Rios inked a minor-league pact with the Rays in February, though his time in Tampa Bay did not last long considering the fact he was dealt to the Mariners for cash considerations on June 4.

With that being said, Rios’ tenure in Seattle lasted all of a week.

Per Baseball Savant, Rios works with a sinker, a four-seam fastball, a slider, a split-finger fastball, and a rarely used curveball.

A native of Puerto Rico, Rios — a former catcher — hails from the same home town as Red Sox manager Alex Cora in Caguas.
