KANSAS CITY -- Royals left-hander Danny Duffy had a less than desirable start to his rehab assignment with the Triple-A Omaha Storm Chasers on Monday -- allowing seven runs on seven hits in 2 1/3 innings. Of his 58 pitches, 33 were strikes.
Duffy, who is recovering from Tommy John surgery, was promoted to Omaha last Friday after pitching three games for Double-A Northwest Arkansas, where he was 0-2 with a 4.22 ERA.
Royals outfielder Jarrod Dyson, who is also on a rehab assignment in Omaha while he recovers from a high ankle sprain, stole four bases and scored two runs on three hits, including a double. Dyson sports a .214 batting average through four games.
