Quentin does not play everyday. It has been a month, not a month and a half, my apologies. He hasn't started a game in five days. They tend to do a "two day on, one day off" with their prospects, at least they're doing that with Quentin now. He has started 17 games in a month - not everday. Once a young guy struggles, they send him to the bench, and you don't have to look far to see how true that is. He had struggled as of late, and then he hits the bench for five days. See? They don't even let a prospect work through his struggles; he's certainly not getting better on the bench.
And with Byrnes next year, it is pretty much a guarantee they will work the same way with Young. If and when he struggles, which he will, being a rookie, they'll stick Byrnes in there and make Young work his way out of a slump through spotty playing time and pinch hit appearances every few days. That's not how you handle your young "studs;" you either play them everyday, and let them work thru slumps, or keep them down in the minors until you're ready to commit to them everyday.
