Ben Nicholson-Smith of Sportsnet.ca is reporting that the Astros have a trade to send minor league RHP Andrew Robinson to the Braves (with a cap tip to House of Houston for the link). Robinson, 26, was one of five Corpus Christi Hooks initially named to this year's Texas League All-Star Game before being promoted to Oklahoma City. With Corpus, he put up a 1.89 ERA with 32 K and 11 BB in 33.1 IP as a reliever; so far in 8 IP with OKC, he has a 4.50 ERA with 7 K and 0 BB. No word yet on what the return might be, but we'll update here as details emerge.
Additionally, the Astros have announced two more international signings today: Panamanian shortstops Juan Pineda and Ozziel Sanchez. Both are 16 years old and both hit right-handed; Pineda is 5'10", 145 lbs., while Sanchez is 5'11", 160 lbs.
