The Rangers receive starting pitcher Dan Haigwood in the swap. Castro is expected to join the Phillies bullpen on Saturday.
The 5-7 Dominican becomes the first Phillies acquisition this season to earn the infamous “_____ is someone we've had our eye on,” treatment in an official Phillies news release. The last time a statement like that was made was last June when Tim Worrell was traded to the Arizona Diamondbacks for Matt Kata, whom scouts “liked for quite some time.”
Phillies scouts, who’ve been camped out at Texas Rangers games since spring training, witnessed a 21-year-old strikeout pitcher who went 0-0 with a 4.32 ERA in four appearances with Texas this season. Opponents batted .200 against him, though he issued seven walks in eight innings.
Last year in Class-A, Castro went 5-5 with a 2.28 ERA and 73 strikeouts in 79 innings. He's had solid numbers throughout his minor league career, almost exclusively as a reliever.
Castro was selected by Kansas City in December's Rule 5 Draft from the Chicago White Sox and was traded to Texas. He began the season with Texas but became available after he was designated for assignment.
The Phillies bit and sent Haigwood packing the day he was named to the Eastern League All-Star Game. Haigwood, 22, is a former 18th-round draft pick and was acquired by the White Sox in the November trade for Jim Thome. The junkball left-hander had 85 strikeouts in 84 innings.
