I agree that Pam has too much influence on what should be baseball decisions, but I'm not so sure what the Astros would take out of the Hunter Pence hot spring (assuming you're talking about 2007) as a reason to either not place Johnson on the opening day roster or promote at some point in April. Pence came in and was honestly one of the catalysts for the Astros' offense in 2007. He was fantastic. His problems, at least on a consistent basis, didn't show up until 2008.
Now, the Luke Scott situation is a perfect parallel, and I agree with the premise that a hot spring doesn't mean Chris Johnson is ready for the majors. But Pence proved a lot of us wrong and was a very, very good player in 2007 and proved he belonged at the ML level.
Good point, however I contend that Pence was not seen by major league teams as a guy who could hurt them in the lineup so he got a lot of challenge pitches. Right in his happy zone and give it up for Pence, he knows what to do with those types of pitches. Is 2007 indicative of his talent? Yes, yes it is. Is it indicative of his understanding how to play at the major league level? No. No it isn't. See the difference?
I don't know if you've seen the level of play at AAA or AA, but suffice it to say, you don't just get fed fastballs in challenge situations in AAA. You are just as liable to see a slider on a 3-2 count or a 2-0 count as you would see a fastball. That's what Johnson needs right now. It was what Pence needed in 2007 to an extent because now he's having to learn this at the major league level. If he doesn't learn it, he'll be an average player hitting in the lower rung of a lineup for the rest of his career. Mind you, that's not a bad gig because when we say a lower rung player, we're still talking about an elite player when measured against all those players who never get the chance to play at that level (and most of them do not have the talent that Hunter has). I never question Hunter's talent (at least not when hitting a baseball, when it comes to playing CF, there is plenty to talk about there!), in 2007 it was about whether he was *ready* for the majors. His hitting was outstanding, but he didn't prove he was ready as evidenced by 2008. It just proved he is one very talented hitter... when all things are in his favor.
The major leagues are about adjustments and to have a better handle on adjustments, sometimes the AAA experience is what does it for a player (sometimes it doesn't). I would dare say that Pence is in no way the same as Albert Pujols who broke into the majors without any AAA experience and has not looked back since. So you may be wrong about what you thought about Pence in 2007, but I know what I thought and it still holds true today.
