The Giants will call up Law to replace Sergio Romo (elbow) in the bullpen, CSN Bay Area reports.
Law missed a good chunk of the 2014 and 2015 seasons after undergoing Tommy John surgery. Prior to the injury, he was considered one of the Giants' better reliever prospects. Law has the repertoire to be effective at the major league level. He will likely be used in middle relief with Hunter Strickland taking over for Sergio Romo as the club's primary setup man.
