Rangers acquire RHP Ramon Aguero

The Rangers have acquired right-handed pitcher Ramon Aguero on a waiver claim from Pittsburgh and assigned him to Triple-A Round Rock.

Aguero, 26, spent the last five seasons with the Pittsburgh organization, going 11-22 with a 4.14 ERA and seven saves in 103 career minor league games, which include 30 starts. The right-hander, who has never pitched above the Double-A level, has recorded 235 career strikeouts against 101 walks, while opponents have batted .266 during that stretch.

He was added to the Pirates' 40-man roster prior to last season and combined to go 2-5 with a 6.14 ERA and three over 25 relief appearances for High-A Bradenton and Double-A Altoona while also enduring three separate stints on the disabled list.

The Dominican native originally signed with the Pirates as a non-drafted free agent on July 19, 2005. He was designated for assignment by Pittsburgh on March 31 after making a pair of relief appearances in the spring.

To make room on the 40-man roster for Aguero, the club has transferred right-handed pitcher Omar Beltre from the 15- to the 60-day disabled list. Beltre had spine surgery Feb. 23 and opened the year on the Rangers’ 15-day disabled list.
