OAKLAND, Calif. -- Another day, another pair of roster moves for the Texas Rangers.
The Rangers placed left-handed reliever Pedro Figueroa on the 15-day disabled list with left elbow inflammation Wednesday, giving them 11 players on the DL.
The Rangers also acquired minor-league outfielder Dan Robertson, 28, from the San Diego Padres in exchange for cash considerations, promoted him to the major leagues for the first time in his career and added him to the 40-man roster.
Figueroa left Tuesday night's game against Oakland after throwing only one pitch in the eighth inning -- he drilled right fielder Josh Reddick in the hip. He'll return to Arlington and have an MRI.
"I don't know what to think," Rangers manager Ron Washington said. "When he walked off the mound it looked bad. The young kid is scared."
The Rangers claimed Figueroa off waivers from Tampa Bay in the offseason. He's 2-1 with a 4.00 ERA in 10 relief appearances.
Robertson has spent his entire career in the Padres system. He was selected in the 33rd round of the 2008 draft out of Oregon State. For his minor-league career, he's batting .304 with 131 steals in 723 games. This season he's hitting .364 (8-for-22) with two home runs, two doubles and five RBI in five games with Triple-A El Paso.
"He's got speed, can play all outfield positions," Washington said. "I can use him to pinch run. He has speed. A good base-runner, can steal bags."
Robertson said he heard he had been traded and was going to the major leagues late Tuesday night after El Paso's 21-9 loss at Las Vegas. After spending six years in the minor leagues, he was shocked by the news.
"I think it's every kid's dream," Robertson said. "I don't know if it's sunk in yet. I'm sure it will sink in when my cleats hit the dirt."
On the mend: Hot-hitting third baseman Kevin Kouzmanoff was out of the lineup Wednesday to rest his stiff back. Kouzmanoff left Tuesday night's game after the top of the fourth inning because of tightness. The Rangers have a day off Thursday.
"Just back stiffness," Washington said. "Don't need to go out there and make it worse."
Feliz watch: RHP Neftali Feliz has been shut down briefly at Triple-A Round Rock to deal with a tired arm and "general soreness," Rangers assistant general manager Thad Levine said. Feliz has been working with team trainers at Arlington. "We envision getting him back on the mound soon," Levine said.
