Mariners' Arquimedes Caminero: Traded to Mariners

Caminero was traded to the Mariners on Saturday for a player to be named later.

After struggling with command early on this season, Caminero has turned in some solid relief appearances since the start of July, compiling a 2.77 ERA and 0.85 WHIP over his last 13 innings for the Pirates. The 29-year-old right hander will bolster the Mariner's bullpen as the team begins the playoff push.
