Minor Moves: Guzman, Abreu, Phelps

Here are the latest minor league transactions, with the newest moves at the top of the post.  All moves reported by Baseball America’s Matt Eddy unless cited otherwise.

• Jesus Guzman elected free agency rather than accept a Triple-A assignment from the Astros, Union Radio’s Pascual Artiles reports (Twitter link).  Houston outrighted Guzman off its 40-man roster earlier this month.  Guzman was acquired from the Padres last December and hit .188/.272/.248 in 184 plate appearances in 2014.
• Second baseman Tony Abreu has elected to become a free agent, leaving the Giants organization.  Abreu has been with the Giants for the last two seasons, appearing in three games with the team in 2014 and 53 in 2013.  Abreu has 615 PA to his name since debuting in the majors in 2007, posting a career .254/.283/.373 line for the Giants, Royals, Diamondbacks and Dodgers.
• Second baseman Cord Phelps has elected free agency.  Phelps played for the Orioles in 2014, appearing in three Major League games and hitting .259/.361/.388 over 403 PA at Triple-A Norfolk.
• The Dodgers re-signed left-hander Robert Carson.  The southpaw posted a 5.74 ERA over 62 2/3 IP in the minors with the Angels and Dodgers in 2014, getting released by L.A.’s red team in May and signing with L.A.’s blue team a week later.  Carson threw 33 innings for the Mets in 2012-13, posting a 6.82 ERA in his brief time in the Show.
• Left-hander Pedro Hernandez has elected to become a free agent, leaving the Rockies.  Hernandez posted a 6.42 ERA in 88 1/3 IP for Triple-A Colorado Springs in 2014, and made one start for the Rockies in July.  The southpaw has a career 7.33 ERA over 66 1/3 IP with the Rockies, Twins and White Sox since 2012.
• The Rockies released and then re-signed right-hander Simon Castro, according to the club’s official transactions page.  He first signed with Colorado in April but didn’t pitch at all in 2014 due to injury.  Castro was ranked as the game’s 58th-best prospect by Baseball America prior to the 2011 season while in the Padres farm system, and was dealt to the White Sox as part of the Carlos Quentin trade package in the 2011-12 offseason.  His Major League experience consists of 6 2/3 IP with Chicago in 2013.
• Left-hander Cesar Cabral, most recently of the Yankees organization, has elected to become a free agent, Examiner.com’s Dan Pfeiffer reports (Twitter link).  Cabral appeared in four games for the Yankees in 2014, totaling one inning pitched and allowing three earned runs.  His Major League resume also includes 3 2/3 IP for New York in 2013.  The southpaw has a 4.01 ERA, 2.58 K/BB rate and 420 strikeouts over 422 1/3 career minor league innings.
