Phillies' Zach Eflin: Feels knee pain Friday

Eflin did not throw Friday because of mild knee soreness, Jim Salisbury of CSN Philadelphia reports.

Analysis:

Manager Pete Mackanin indicated the knee issue was not serious. Eflin had surgery on both of his knees last fall to address chronic tendinitis. He said earlier that his knees were feeling great, so this pain could just be a normal post-surgery issue.
