Left-hander Drew Pomeranz, the highly regarded pitching prospect considered the key acquistion in the July trade of Ubaldo Jimenez, was arrested in Oxford, Miss., Friday morning and charged with disturbing the peace.

Pomeranz was arrested at 1:25 a.m. ET and released on a cash bond three hours later, according to The Associated Press. He was listed in jail documents under the name Thomas, which is his given first name.

"The Rockies organization is aware of the unfortunate incident involving Drew Pomeranz that took place in Oxford, Miss.," the club said in a statement issued Friday afternoon. "We have been in contact with Drew and his representatives and we will continue to gather more information. Both Drew and our organization understand the serious nature of the situation."

The 22-year-old was an All-America selection at the University of Mississippi, located in Oxford. He was Cleveland's fifth overall selection in the 2010 First-Year Player Draft.

He signed too late to begin his professional career in a full-season league in 2010. This year, Pomeranz went 3-2 with a 1.87 ERA in 15 starts for Class A Kinston and made three appearances for Double-A Akron before the trade to Colorado.

After pitching 10 shutout innings in two starts for Double-A Tulsa, Pomeranz made his big league debut in September and went 2-1 with a 5.40 ERA in four starts for Colorado.
