BOSTON, MA – The Boston Red Sox today announced the following roster moves:
- The Red Sox acquired right-handed pitcher Yacksel Rios from the Seattle Mariners, in exchange for cash considerations.
- To make room for Rios on the 40-man roster, the Red Sox designated right-handed pitcher Ryan Weber for assignment.
- To fill Weber’s spot on the active major league roster for tonight’s game against the Toronto Blue Jays, Boston recalled infielder Michael Chavis from Triple-A Worcester.
Chief Baseball Officer Chaim Bloom made the announcement.
Rios, 27, has made 69 major league appearances with the Philadelphia Phillies (2017-19), Pittsburgh Pirates (2019-20), and Mariners (2021), going 5-2 with a 6.47 ERA (52 ER/72.1 IP). Selected by Philadelphia in the 12th round of the 2011 June Draft, the right-hander spent parts of nine seasons in the Phillies organization before the Pirates claimed him off waivers on August 3, 2019.

Weber has appeared in 60 major league games (16 starts) with the Atlanta Braves (2015-16), Mariners (2017), Rays (2018), and Red Sox (2019-21), making Boston’s 2020 Opening Day roster.
Chavis, 25, has appeared in 11 games over two stints with Boston this season.
