Bronx, NY (SportsNetwork.com) - The Kansas City Royals placed pitcher Danny Duffy on the 15-day disabled list Monday with left biceps tendinitis.

The move is retroactive to May 17.

Duffy has made eight starts for the Royals this season, going 2-3 with a 5.87 ERA.

The team filled the roster spot by recalling lefty Brandon Finnegan from Triple-A Omaha. Finnegan has made four relief appearances for the Royals thus far in 2015.
