Sure thing, if Stro had continued his slump for the rest of the season, he most likely wouldve been sent down to AAA for a short time to work things out. This has happened to many great pitchers, and doesnt always destroy someones confidence like others suggested.
What most recent bandwagon jumpers don't realize is that our Roy Halladay was sent down to minors after 1.5 years in the bigs. His first few starts were amazing and almost had a no-hitter in his 2nd start.
But then in Apr/May of 2000, ML hitters caught up to his 95mph heater. Straight over the top and straight as an arrow. They sent him down, not to AAA but to A Dunedin to rebuild his mechanics for the next year.
He came back with a 3/4 delivery with a 93mph fastball & cutter that moved everywhere. The rest as they say is history, he finished top 5 in CY every year he was not injured after that for the next decade.
So no shame in sending young pitchers or hitters down to work on their game.
