"Time ran out Wednesday morning on the Royals' willingness to wait for right-hander Kyle Davies to develop into a reliable starting pitcher.

The Royals requested unconditional release waivers on Davies, 27, in order to clear space on their 40-man roster for the arrival of catcher Salvador Perez from Class AAA Omaha.

The move comes with Davies on the 15-day disabled list for the second time this season because of arm problems. He was 1-9 with a 6.75 ERA this season in 13 starts.

Players can be released while on the disabled list. If claimed by another club, they remain on the disabled list for that club. But any club would also assume the balance of Davies' $3.2 million salary - or roughly $900,000."
