So, now that Manoah is off to the races it got me thinking of kids called up who made a strong first impression here.
Since it is first call up Eichhorns amazing rookie year doesn't count (he was up for a period as a starter before that but didn't lose rookie legibility). Looking at starters with ERA+ of 100 or better or close enough to be interesting. Or guys who were amazing later (like Carpenter) while skipping 'meh' guys like Stottlemyre who had bad rookie seasons and decent but not 'wow' careers.
- Luis Leal: 1980 3-4 96 ERA+ in 10 starts/3 relief 59 2/3 IP
--------------end of first great era-------------------- Goose Gozzo: 1989 4-1 77 ERA+ over 3 starts, 6 relief - doesn't qualify but it was so amazing when he was called up and did well until put into the pen, 4-0 his first 4 appearances.
