UPDATE - The Mariners have announced the acquisition of Harang, adding that they've sent minor league reliever Steven Hensley to the Rockies. To make room on their roster for Harang, Seattle designated Kameron Loe for assignment.
UPDATE - The Rockies and Mariners have agreed on a Harang trade, according to Jon Heyman of CBS Sports. The deal is pending MLB approval, which Rosenthal notes is required for transactions in which $1 million or more is exchanging hands.
Rosenthal adds that the teams are working through the final details of the trade, "including approval from the commissioner's office." There's no word on what the Rockies would be receiving in return for the veteran right-hander, but it could be a player to be named later or cash considerations since Harang was recently designated for assignment by the team.
The Rockies recently acquired Harang from the Los Angeles Dodgers in exchange for veteran catcher Ramon Hernandez. Los Angeles also shipped $4.25 million to Colorado, who immediate designated Harang for assignment.
Harang entered the spring as part of the Dodgers' pitching surplus. He was left without a spot in the team's rotation -- along with Chris Capuano and Ted Lilly -- and LA ultimately elected to trade him. The 34-year-old posted an ERA of 3.61 over 31 starts for the Dodgers last season. He owns a career ERA of 4.19 over 11 seasons in the majors.
