Catcher Guillermo Quiroz worked with Kickham during Spring Training and described him as a competitor.
"He's going to compete for sure," Quiroz said. "I could see he wanted to be on the mound and to show he can pitch here."
Kickham has gone 3-1 with a 1.72 ERA over his last five starts with Fresno.
"His stuff is good," Quiroz said. "He was working on a changeup in Spring Training and has a good fastball and slider."
Bochy said Buster Posey will catch Kickham, who was drafted by the Giants in the sixth round of the 2010 First-Year Player Draft.
Kickham was 4-9 with a 5.25 ERA during his senior year at Missouri State, where he studied biology and pre-med. He struck out 103 in 96 innings.
