As an old school baseball fan I love this topic. Question for all those using words like "shellshocked, not major league ready" etc., do you realize that Charlie Finley built a 3 time world championship team by putting kids in the majors? Vida Blue debuted at age 19, won a Cy Young and an MVP at 21. Catfish Hunter threw 133 innings in the majors before turning 20, posted a sub 3 ERA at 21, and pitched a perfect game at 22. Blue Moon Odom also debuted at age 19. The opening day pitcher for the Brewers in their inaugural season, Lew Krausse, pitched for Finley's A's at age 18 pitching a 3 hit complete game shutout in his debut. Though Rollie Fingers didn't debut until 21, he never pitched an inning in AAA. Baltimore was another team that brought up pitchers very young. Jim Palmer came up at 19 and joined a rotation that already had 20 year old Wally Bunker, who the year before at 19, had gone 19-5 with a 2.69 ERA. Milt Pappas, 18, and Dave McNally, 19, were other Orioles of note to hit the big leagues as teenagers. Were young men more mature that they could handle being thrown into the big leagues earlier back then? I think not. Back then, kids grew up exposed to a lot less than they are today. Today, it's all about controlling arby years, protecting young arms etc. While that may be fine, that has led to the big leagues being filled with guys of lesser talent. I have no doubt there are guys in A ball with the stuff to get major league hitters out. Whether any are in the Brewer system is questionable, but it's certainly possible. I would certainly bring up Rivas and Rogers sooner rather than later and let them start games. My gosh both will be 25 by January. Back in the day, that would be considered ancient for a rookie pitcher. What on earth do the Brewers gain continuing to start Dave Bush? Maybe, just maybe if Wolf has to miss a start or two, they go to either Rivas or Rogers instead of trotting Capuano out there again. If there's any other guys who would have to be added to the 40 man in the offseason anyway to avoid rule 5 exposure, why not bring them up in September if they had a good year. I'd certainly also bring up Jeffress because he's already on the roster too. As for Butler, no. I don't think he's done enough to retain a 40 man spot.
