Gaudin provided three innings of relief and allowed one run after Kickham lasted just 2 1/3 innings in a 6-3 loss.
"We needed innings Tuesday, and he could do it," Bochy said of Gaudin. "He has experience as a starter, and it's nice to have a guy as versatile as Chad."
Bochy said it makes sense for the club to call upon its long reliever rather than making another roster move because of the Giants' off-days next Monday and Thursday.
Gaudin has sparkled in his role this season -- he has a 2.05 ERA in 30 2/3 innings -- after bouncing around from club to club during his 11-year big league career. He recorded his longest outing of the season at Toronto on May 15, when he pitched 3 1/3 innings and threw 72 pitches.
