The Pirates and Mariners have completed the deal that sent righty Arquimedes Caminero to the Mariners a few weeks back. Per an announcement from Seattle, lefty Jake Brentz and righty Pedro Vasquez will go to Pittsburgh to wind up the trade.

Caminero, 29, has been a solid piece for the M’s since the deal, cutting his walk rate but otherwise largely continuing to deliver useful but hardly world-beating frames. On the year, he has thrown 55 innings of 3.60 ERA ball with 7.0 K/9 against 4.1 BB/9.

Pittsburgh will pick up a pair of young arms in return. The 21-year-old Brentz has experienced some command issues early in his career, but generated better than a strikeout per inning at the Class A and High-A level for most of the season. Vasquez, 20, earned a mid-season promotion out of Rookie ball and has turned in a 2.28 ERA with 6.2 K/9 against just 0.8 BB/9 in his eight starts at Class A Clinton.
