Royals' Danny Duffy: Feeling good after side session Friday

Duffy (oblique) "felt fine" after throwing a bullpen session Friday, Jeffrey Flanagan of MLB.com reports.

Duffy is scheduled to throw again Sunday, and if all goes well, he'll pitch to hitters Tuesday after the Royals return from their current road trip. So far, Duffy appears on track for a return around the All-Star break.
