The Phillies lost another of their top prospects Monday when the team announced that minor-league outfielder Domingo Santana has been assigned to the Houston Astros to complete the July 29 Hunter Pence trade.

That means the Astros acquired pitcher Jared Cosart, first baseman Jonathan Singleton, pitcher Josh Zeid and Santana in the deal. Cosart was considered the Phillies' best pitching prospect before the deal and Singleton was considered the best position player in the organization. It could be argued that Santana was the organization's best outfield prospect.

Santana, who just turned 19 this month, was hitting .269 with 29 doubles, four triples, seven home runs and 32 RBIs for single-A Lakewood. A native of the Dominican Republic, he also played in the South Atlantic League as a 17-year-old last season, but was demoted to Williamsport after hitting .182. He had shown tremendous improvement in his second full professional season.

In other news, Baseball America reported that the Phillies have agreed to terms with first-round pick Larry Greene. The report said that the high school outfielder from Georgia received a $1 million signing bonus.

The deadline for signing drafted players is midnight Monday. The Phillies are also still hopeful they will sign second-round pick Roman Quinn, a high school shortstop from Florida.

The team also announced the official signing of a minor-league contract by pitcher David Bush, a Conestoga High product. Bush will report to triple-A Lehigh Valley.
