Minor Moves: Jason Jaramillo, Kila Ka'aihue, Aaron King

Astros release Jason Jaramillo

The Houston Astros have released catcher Jason Jaramillo from AAA Oklahoma City, according to the Pacific Coast League's official transactions page. After signing a minor league deal with Houston in January, the 30-year old ex-Pirate has posted a .130 average with 7 RBI in 23 games this season. In 119 games of major league action with Pittsburgh from 2009 to 2011, Jaramillo hit .235 with 4 HR and 38 RBI.

Diamondbacks release Kila Ka'aihue

The Arizona Diamondbacks released first baseman Kila Ka'aihue from AAA Reno, according to the Pacific Coast League's official transactions page. Ka'aihue elected to exercise the opt-out clause in his contract, according to Julia Lopez of KRNV-4 in Reno. The 29-year old Hawaiian, who signed with Arizona as a free agent in November, has posted a .313/16 HR/50 RBI slash line so far this year for Reno, and will probably latch on with another organization soon after producing in the minors. In 126 career games with the Royals (2008, 2010-2011) and Athletics (2012), Ka'aihue has hit .221 with 15 HR and 46 RBI.

Red Sox sign Aaron King

The Boston Red Sox purchased the contract of outfielder Aaron King from the Grand Prairie AirHogs of the independent American Association, according to a release from the team. The 24-year old was drafted as a pitcher by the Giants in the seventh round of the 2008 draft, but struggled mightily in the minors and decided to become an outfielder at the beginning of the season. In nine games with Grand Prairie, he hit .389 with 2 HR and 5 RBI.
