Right-handed reliever Ricardo “Ricky” Rivas was the only player signed by the Dodgers for a Minor League job from 85 aspirants who participated in an open tryout at Camelback Ranch-Glendale Thursday. Rivas, 26, went 2-1 with a 4.82 ERA in 23 relief appearances last year for independent El Paso. He was a 48th round pick of Pittsburgh out of El Paso Community College in 2004 but did not sign and played two years at Oklahoma State. — Ken Gurnick
