In Wednesday’s seesaw loss against the Cubs, Jandel Gustave came within one pitch of throwing an immaculate innings: nine pitches, nine strikes, three strikeouts. Gustave had been effective before that, but this was an eye-opening performance. Gustave, who the Giants signed to a minor-league contract over the offseason, had a 6.15 ERA at Sacramento this year (though in PCL numbers that’s like 4.15). His call-up was more about keeping him in the organization than needing to get his arm in the majors.
His showing thus far has been evidence of why the Giants wanted to hang onto him.
