INDIANAPOLIS — Warriors guard Klay Thompson is poised to have a new housemate: his younger brother, Trayce, who was signed off waivers Thursday by the Oakland A's. "He texted me, actually, and asked if I had room for a roommate," Klay, who is a year older than Trayce, said before Thursday night's game against the Pacers. "Luckily, I do." Trayce joins the A's hoping to resuscitate a once-promising career. Three years after batting .295 as a rookie with the Chicago White Sox, he is struggling to stick in the majors. Trayce hit .212 with nine homers and 33 RBIs in 95 games with the Triple-A Oklahoma City Dodgers last season. In 27 games with the Los Angeles Dodgers, he batted .122 with a homer and two RBIs.
