The Mariners have announced that they’ve acquired righty reliever Arquimedes Caminero from the Pirates for a player to be named later and a conditional player to be named later. To clear roster space, they’ve designated righty Blake Parker for assignment.
The Mariners claimed Caminero before working out a deal, as MLB.com’s Greg Johns writes. The 29-year-old Caminero is one of baseball’s hardest throwers — his average fastball velocity this season has been 97.7 MPH, and he routinely touches triple digits. He does, however, struggle with his control, which might explain why most teams passed on him as a waiver claim despite his fastball and near-league-minimum salary. After a relatively successful 2015 season in which he posted a 3.62 ERA, 8.8 K/9 and 3.5 BB/9, Caminero has posted a 3.51 ERA but with just 7.0 K/9 and a very high 4.8 BB/9 this year (although he has fared much better since returning from a DL stint in June).
The Mariners (who recently promised they would be active on the August trade market) will become the latest team to try to turn Caminero’s electric arm into a high-performing one. The Pirates, meanwhile, will move on to other relief options in a new-look bullpen that also recently added Antonio Bastardo and swapped Mark Melancon for young former Nationals lefty Felipe Rivero. MLB.com’s Adam Berry suggests (via Twitter) that Caminero’s departure could clear space in the bullpen for Jeff Locke, who could be bumped from the rotation in favor of a younger option like Chad Kuhl, Steven Brault or Tyler Glasnow.
The 31-year-old Parker signed with the Mariners as a minor league free agent last winter and has spent most of the year with Triple-A Tacoma, where he posted a 2.72 ERA with an excellent 12.7 K/9 and 2.5 BB/9. The Mariners added him to their roster this week, and he pitched in just one game for them before being designated.
