Duffy, Paulino progressing well in rehab stints

KANSAS CITY -- Pitchers Felipe Paulino and Danny Duffy are doing well in their rehabilitation assignments at Surprise, Ariz. Both underwent Tommy John surgery last season.

"They're doing fine. I think both of them threw [Saturday]," manager Ned Yost said. "Duffy threw 20 pitches in a game and Paulino threw like 25 pitches in BP with good results. They're fine."

Both are aiming for Minor League pitching assignments in the next month or two.
