I mean, I think the notion that Dusty Baker - a man with a career 9.5 BB% - is a poor manager because of some quote he made 7 years ago is pretty silly. Focusing on the "clogging the bases" part of it is humorous, but lacks the context of the whole quote:
“I’m big on driving in runs and scoring runs,” Baker said. “Guys in the middle should score about close to equal to what they drive in. On-base percentage, that’s fine and dandy. But a lot of times guys get so much into on-base percentage that they cease to swing. It’s becoming a little bit out of control.
“What you do is run the pitcher’s count up, that helps,” Baker said. “You put him in the stretch, that helps. But your job in the middle is to either score them or drive them in. The name of the game is scoring runs. Sometimes, you get so caught up in on-base percentage that you’re clogging up the bases.”
I think the bolded section is the important section. It's not so much the guys already on base that are "clogging the bases" but it's the guys who passively look for walks with men on second and third instead of looking for pitches to drive in runners.
I'm not sure as a stats guy that I agree with the contextualized sentiment either, but it's not an uncommon way to think in baseball. Being a strong believer in situational hitting is far different from "not believing in OBP" or whatever nonsense this quote has become.
Let's take this example - men on second and third with one out. Your AVERAGE run expectancy in that situation is 1.38 runs. If your hitter takes a walk to load the bases, your AVERAGE run expectancy goes up to 1.545 runs. That's a 12% increase in run expectancy - so easy decision right?
But what if the hitter who walks is a significantly better hitter than the one who follows? What if it's Bryce hitting 3rd and Yunel hitting 4th? What if it's the 8 inning and you're down a run, rather than the 4th inning up 3 runs?
Anyways, I just think it's possible that Dusty Baker isn't as stupid as he's made out to be.
