BALTIMORE (AP) -- The Philadelphia Phillies acquired left-hander Fabio Castro from the Texas Rangers on Thursday for minor league pitcher Daniel Haigwood and cash.

Castro was 0-0 with a 4.32 ERA in four appearances with the Rangers earlier this season. He was designated for assignment on June 24.

"Fabio is someone we've had our eye on since the Rule 5 draft approached last December," Phillies assistant general manager Ruben Amaro Jr. said. "He has a quality arm, is young and someone we are pleased to have in our organization. We feel that he has a chance to develop into a setup-type reliever."

The 21-year-old Castro held right-handers to a .192 batting average (5-for-26) during his brief stay in Texas. He is expected to join the Phillies in Toronto on Friday.

Haigwood, a left-hander, was 2-5 with a 3.54 ERA in 15 starts with Double-A Reading. He was acquired in the November trade that brought Aaron Rowand and Gio Gonzalez from the Chicago White Sox for Jim Thome.
