According to T.R. Sullivan of MLB.com, the Rangers "would love to take a high upside college pitcher who could shoot through the system" with their 11th overall pick this June. Sullivan suggests Shooter Hunt, Tanner Scheppers, and Christian Friedrich as possibilities. Scheppers may be out of the picture given the stress fracture of his shoulder.
ESPN’s Keith Law ranked his top 60 for the draft on May 10th, and he considered the top college pitchers to be Aaron Crow, Brian Matusz, Scheppers, Friedrich, Josh Fields, and Hunt. In their May 16th mock draft, Baseball America picked high school first baseman Eric Hosmer for Texas.
