The Mariners added a power arm to their bullpen on Saturday morning, acquiring hard-throwing right-handed reliever Arquimedes Caminero from the Pittsburgh Pirates in exchange for a player to be named later and a conditional player to be named later based on Caminero’s performance.

To make room on the Mariners’ 40-man roster, right-hander Blake Parker, who was just called up, was designated for assignment. Right-hander Taijuan Walker will take Parker’s spot on the 25-man roster when he’s activated from the disabled list to make the start on Saturday night. Caminero isn’t expected to be in Seattle for Saturday night’s game. But he is out of minor league options so he will join the team, likely by Monday. The Mariners will have to make another roster on their 25-man roster to make room for him.

Caminero, 29, made 39 relief appearances with the Pirates, posting a 1-2 record with a save and a 3.51 ERA. In 41 innings pitched, he’s struck out 32 batters, but he has issued 22 walks. In his last 21 appearances, with a disabled stint (quad strain) mixed in, he’s posted a 2.13 ERA with 19 strikeouts in 25 1/3 innings pitched. Caminero has appeared in 131 games over four seasons, posting a career 3.86 ERA with 125 strikeouts and 58 walks in 135 1/3 innings pitched. Command has been an issue for much of his career.

From Brooks Baseball … Caminero has a fastball that can touch 99 mph to go with a cutter, a sinker, a splitfinger and seldom used breaking pitch.


Parker appeared in one game with the Mariners, throwing a scoreless inning of reliever vs. the Red Sox. In 38 appearances with Tacoma this season, he was 1-2 with 19 saves and a 2.72 ERA. The Mariners signed him as a minor league free agent this offseason.
