Angels' Jesus Castillo: Returns to Double-A

Castillo was optioned to Double-A Mobile on Sunday.

Castillo never found his footing this spring as he allowed 10 runs (nine earned) on seven hits and eight walks across only three innings. The 23-year-old had a 4.94 ERA, 1.30 WHIP and unimpressive 60:31 K:BB over 98.1 innings at Mobile last season.
