Here are today's minor moves, with the latest up top…
- The Mariners released minor league catcher Ralph Henriquez in order to make room for 2012 No. 3 overall pick Mike Zunino on their Double-A roster, according to Larry Stone of the Seattle Times (on Twitter). The 25-year-old Henriquez was a second round pick by the Astros in 2005 but has just a .592 OPS in eight minor league seasons.
- The Rockies have signed 16-year-old Venezuelan shortstop Luis Castro for $50K, reports MLB.com's Jesse Sanchez (on Twitter). Castro had originally signed with the Blue Jays for $800K last month, but the contract was voided due to health concerns.
- The Angels have signed right-hander Tony Pena according to the MLB.com transactions page. The 30-year-old had Tommy John surgery last August, and has pitched to a 4.43 ERA with 6.3 K/9 and 3.1 BB/9 in 379 2/3 big league innings with the Diamondbacks and White Sox.
- The Rockies have signed right-hander Jeff Marquez, also according to MLB.com. The 28-year-old posted a 6.69 ERA with 5.3 K/9 and 4.0 BB/9 in 76 2/3 innings with the Mariners' Triple-A affiliate this year. Marquez has four big league appearances to his credit, one with the White Sox (2010) and three with the Yankees (2011).
