Trivino (back) is expected to be available for Thursday's game against the Tigers, Matt Kawahara of the San Francisco Chronicle
Manager Bob Melvin revealed Wednesday that Trivino has been dealing with back spasms recently, but he's apparently feeling better and should be available out of the bullpen. The right-hander has struggled across his last three appearances and has allowed six runs on six hits and two walks while striking out three in 2.1 innings during that time.
