Chen activated, Collins demoted, Joseph designated for assignment

The Royals have made a series of transactions today, activating LHP Bruce Chen from the 60-day disabled list, optioning LHP Tim Collins to Omaha, and designating LHP Donnie Joseph for assignment to clear a 40 man roster spot for Chen. Bruce had been out since April 24 with a bulging disc in his back. In four minor league starts on rehab, Chen had less than stellar results with an 8.22 ERA, although he did have a 16-3 strikeout-to-walk ratio. Chen was in the rotation when he landed on the disabled list, but will pitch out of the bullpen with Danny Duffy pitching so well in his return.

Collins is shipped to Omaha after a very disappointing start to his season. Collins had a 4.15 ERA in 18 appearances with 10 walks and just 10 strikeouts in 17.1 innings of work. Lefties were hitting .316/.391/.421 off of him. He had battled a flexor strain injury earlier this year that landed him on the disabled list.

Joseph made just one appearance for the Royals this year, giving up six runs while retiring just two hitters. The 26-year old  had a 3.86 ERA in 25.2 innings for Omaha, and will now be jettisoned off the 40 man roster.

Michael Mariot, who has not appeared in a game since June 16, and has an ERA of 6.65, remains on the roster for some reason.
