A while ago, Bill James used to name his Ken Phelps all stars. These were player who had low BA's, but high walk totals and high HR. Back in the 70's, GMs used to dismiss these players and they would languish for years in the minors. James argued that they were useful because the walks gave them high OBP, the HR gave them high SLG. Thus they had high OPS--and were valuable hitters despite hitting .250 or below, being slow and usually poor defensively. James's OPS stat caught on and is a major tool in the 80's game. And Ken Phelps and his ilk accordingly command fairly high prices in the 80's game as well.
But others have, I think, shared my experience that it's hard to get guys like Phelps to perform satisfactorily in the 80s game--they may hit homers and draw walks, but their BA's are more like .170 or .180 than like .240 or .250. And a .170 hitter will kill you even with lots of walks and HR because he's making so many outs. Instead of an .800+ OPS, he might be more like .620. If the guy hit .230 he might still be valuable, but nobody can hit .170 and not hurt the offense.
I have a theory about this that I'd like to check with the more math-oriented. I mentioned the theory on another thread and Jablowmi urged to to explain it further. Anyway, my theory grows from the fact that if you look at one of Ken Phelps's cards, what you see is a ton of HR and walks, and maybe a double point some where, but only a couple of points with singles. What I think happens is that the strato card designers essentially say--"this is a walk and HR guy. He's going to have to get most of his singles off the pitchers' cards." And that would work under most circumstances--but the pitchers in the 80's game have fewer singles on their cards (a lot fewer) than normal pitchers, since this is the cream of the pitching crop. This might take 20 points off the BA of a high BA hitter, on average, but their overall performance can sustain that. OTOH, it's catastrophic for a Ken Phelps, who is relying almost completely on the pitcher's card for his singles and BA.
Anyway, I've had experiences with Phelps hitting .136 (admittedly in 66 AB), Ron Kittle hitting .180, HoJo hitting .190 (in longer trials), etc. Even Whitaker has done this to me in his .250 BA, high homer year. So, what it may mean is that we can [b:131efd85c4]expect [/b:131efd85c4]these guys to significantly underperform in BA against typical 80's game pitching. They're hurt by the good pitching more because they have fewer hits on their own cards.
Anyway, what do you think? Have others shared my experience with the Ken Phelps types. I know Sykes likes Tettleton and he's basically of this player-type. What are Tettleton's BA's like over the long haul? Have I just had a few bad experiences or does this explanation generally hold water? Anyway, as I now look for players I'm tending to look not only for high OBP but also for decent BA--the OBP shouldn't be mostly walks.
