Whisenhunt’s first two innings in the majors were also a struggle. The third batter he faced, Nick Gonzales, sent his signature changeup into the left-field bleachers for a solo homer. In the second, the Pirates scored three runs on Isiah Kiner-Falefa’s two-run double and Tommy Pham’s RBI single, both hits also being against the changeup.

The last 48 hours were quite nerve-wracking for Carson Whisenhunt. The Giants’ No. 3 prospect was slated to start for Triple-A Sacramento on Saturday, but he ended up being scratched at the last minute.
