A variety of outlets have reported that the Rangers have traded Guillermo Moscoso to the Oakland A's for righthanded minor league pitcher Ryan Kelly.
Moscoso was designated for assignment to make room on the 40 man roster for Adrian Beltre, and the Rangers had 10 days to trade, waive or release him. Moscoso wasn't likely to clear waivers, so a trade was expected.
Kelly, who will pitch at age 23 this season, was in the Pirates system until December, 2010, when he was dealt to the A's for infielder Corey Wimberly.
Kelly apparently throws hard and has put up impressive peripherals in low-A the last couple of years after missing good chunks of 2007 and 2008 with injuries.
He's a fringe prospect at best right now, but appears to be someone who could potentially have a future in a major league bullpen.
