Andrew Cashner, who had a terrific starting debut with the Cubs back on April 5 before succumbing to sore shoulder and going on the DL, has experienced tightness in his rehab and will undergo an MRI, CSN Chicago’s Patrick Mooney reports.
Cashner was expected to pitch in an extended spring training game today as part of his rehab.
The 24-year-old Cashner appeared in 53 games as a reliever during his rookie season in 2010 before beating out Carlos Silva for the final spot in the Cubs rotation this year. He allowed one run and two hits in 5 1/3 innings against the Diamondbacks in his season debut before leaving with shoulder soreness. He was diagnosed with a rotator cuff strain and placed on the DL.
If there’s further damage in Cashner’s rotation cuff, there’s a good chance the Cubs will be without him for the rest of the season. Doug Davis, who made his Cubs debut Saturday as the replacement for James Russell in the rotation, might be needed a whole lot longer than expected.
