Elias, 29, has 55 games (50 starts) of major-league experience over four seasons but has spent the entirety of the 2018 season with the Red Sox’s Triple-A affiliate in Pawtucket. Over four relief appearances for the PawSox, Elias had posted a 1.23 ERA with a 0.55 WHIP over 7.1 innings. For his major-league career, he has a 4.20 ERA and 1.34 WHIP over 287 innings.
Elias came up through the Mariners organization, signing as an international free agent at the age of 22 in 2011 after defecting from Cuba. He spent parts of the 2014 and 2015 seasons in the big leagues with Seattle, but he was dealt to Boston (along with Carson Smith) in December of ‘15 in exchange for Wade Miley and Jonathan Aro. Now he’ll return to his original organization and hope to make an impact on a bullpen that has been somewhat depleted by the loss of David Phelps.
