The St. Louis Cardinals will recall top prospect Jordan Walker before Friday's game, according to a report.

Walker was demoted on April 26 because the Cardinals wanted him to work on an improved launch angle off the bat. 

He slashed .274/.321/.397 with three doubles, two home runs and 11 RBIs in his first 20 Major League games. However, he had a 58.5 percent ground-ball rate.
