Colome and outfielder Denard Span were traded from the Rays to the Mariners on Friday in exchange for right-handed pitchers Andrew Moore and Tommy Romero, Marc Topkin of the Tampa Bay Times reports.
Colome has acted as the Rays' closer thus far, but he'll slide into a setup role in front of Edwin Diaz in Seattle, a huge hit to his value. He's 11-for-13 in save opportunities this season and sports a 4.15 ERA with 23 strikeouts across 21.2 innings. Mariners general manager Jerry Dipoto expects Colome to arrive in Seattle on Sunday, Ryan Divish of The Seattle Times reports.
