Minor Moves: Townsend, Royals, Green, Geltz

 Here are some of today's minor moves:

• Tyler Townsend, an Orioles' first base prospect who impressed when healthy but could not overcome his myriad injuries, has announced his retirement, reports Steve Melewski of MASNsports.com. Despite his "great swing," Townsend ultimately "was just not enjoying the process" due to the series of hamstring, wrist, and hip injuries he suffered, explained O's director of player developmet Brian Graham.
• The Royals have released minor league pitchers Michael Giovenco, Jose Jimenez, Leondy Perez, and Elisaul Pimentel, reports Bob Dutton of The Kansas City Star. K.C. originally acquired Pimentel before the 2010 trade deadline along with catcher Lucas May, in a deal that sent Scott Podsednik to the Dodgers.
• Marlins infielder Nick Green has been "sent down" by Miami and "may consider opting out" of his deal with the club, CBSSports.com's Jon Heyman tweets. Green elected free agency when he was outrighted to Triple-A by the Marlins last fall, only to return to the club on a minor league deal in January.
• Righty Steve Geltz was outrighted by the Angels today and will head to the club's Triple-A affiliate, MLB.com's Alden Gonzalez reports on Twitter. The move opens a 40-man roster spot for the Angels. Geltz, 25, saw his first big league action last year for L.A., logging just two innings in relief. While Geltz posted a 0.36 ERA in 25 1/3 Double-A innings last year, he sported a 5.08 ERA in his 33 2/3 innings at Triple-A Salt Lake.
