Floyd among three waived by Padres

De La Cruz promoted; Burke undergoes surgery

The Padres on Thursday requested unconditional release waivers on right-handers Cha Seung Baek, Shawn Hill and outfielder Cliff Floyd and announced they had selected the contract of right-hander Eulogio De La Cruz from Triple-A Portland.

Meanwhile, right-hander Greg Burke underwent arthroscopic debridement on his right shoulder Wednesday in La Jolla, Calif. Burke, 27, made his Major League debut with the Padres this year and went 3-3 with a 4.14 ERA in 48 relief appearances.

Baek, who is 16-18 in 59 career games with Seattle and San Diego, missed the entire 2009 season after being placed on the disabled list with a strained right forearm. Hill went 1-1 with a 5.25 ERA in three starts for the Padres before having his season cut short with inflammation of his right elbow. Floyd had two hits in just 16 at-bats for San Diego.

De La Cruz, 25, made three appearances for San Diego this year, posting a 5.40 ERA. He spent most of the year at Triple-A Portland, where he went 2-6 with a 3.12 ERA in 48 games (four starts).
