Rays shortstop Yunel Escobar's claim on revocable waivers by Oakland has raised some concern in the Escobar camp, which apparently prefers he stay in Tampa Bay where he felt he had finally found a home. "I am very concerned with Yunel having been selected on waivers by Oakland," Escobar's agent, Alex Esteban, told CBSSports.com on Sunday night. "While I believe Oakland is an excellent organization, I don't feel that it is the best organization for him." Escobar has seemed to get along swimmingly in St. Pete after some rough moments in previous stops in Atlanta and Toronto. He happily signed an extension that will pay him $13 million total in 2015 and '16. While Escobar, who makes $5 million this year, isn't having his best season, it should be no surprise the aggressive A's, whose starting shortstop Jed Lowrie is out with an injury, claimed him. Oakland could certainly use Escobar, and since Lowrie is a free agent after the year, he definitely fits -- though Mark Topkin of the Tampa Bay Times late Sunday characterized the chances for a trade as less than likely, meaning the Rays will probably retain him. Regardless, Escobar evidently prefers not to go; he was seen as somewhat quirky in his previous stops but fits nicely with the Rays
