The Astros have considered as many as five players with the first overall pick, but they are expected to take Stanford University right-hander Mark Appel, according to sources. Georgia high school outfielder Byron Buxton has also been in the running for quite some time. "There is no unanimous or consensus guy," one scouting director said. "Buxton is probably the best position player prospect, but he is a high school guy, which makes for risk. Last year was unclear because there were six or seven guys who were worthy. This year is unclear because there are no true 1-1 caliber talents."
