I love what cp176 just wrote about reducing baseball to stats, but I also have to say the following about managing.
To me the central reality of baseball, which makes it vastly different from all other sports, is the confrontation between pitcher and batter. Last night, for example, the two teams combined for 70 at bats (including the 6 walks) and 310 pitches. Ted Williams claimed the most difficult skill in all of sports is to hit a round ball with a round bat squarely, and I would argue that throwing almost as hard as you can with the accuracy of a knife thrower, but at 66 ft, not 15', is probably at least as hard.
I would further argue that managers can effect that central reality only at the margins. Last night we won because Pomeranz had a great night for 6 innings, our bullpen was again terrific, and Bogie hit that 2 run dinger--and that neither manager had anything to do with that outcome. Indeed, Eckersley pointed out that Pomeranz was darn lucky when he threw a perfect home run ball to Napoli but he swung a micro micro second too soon and pulled it foul.
The Sox have now won 4 straight games and are back in the race .5 games behind the Orioles and 3 behind the Yankees. And the only dicey game was probably Wednesday's game with Sale on the mound when we needed that huge 7th inning rally to come from behind. In that game--afterwards, actually--I made a big deal about how Farrell pinch hit twice during that rally to keep it going. Big deal, really? Yes, good moves, the right moves, but hardly unexpected. Plus they don't work if Moreland and Rutledge K or GIDP instead of getting singles.
Or take the three games before that--all losses at Oakland--that took the Sox down to .500 and regenerated talk that Farrell was climbing the steps of the guillotine with DD playing the part of Madame DeFarge. We lost two of those games 8-3. And in the middle game, another one Sale started, we lost 3-2 in 10 innings because Hembree threw two balls and then the ever popular fastball down the middle so that Canha could hit the game winning dinger. I mean, seriously, what the hell was Farrell doing so badly to cause those three losses? Not much, I would argue.
A small sample size, granted, but those 7 games to me underscore that Whitey Herzog or somebody was absolutely right when he said that the difference between a so-so manager and a good one is a great bullpen because the bullpen is the only weapon a manager almost controls because he decides who stays in, who goes in, and when. Last year when the bullpen was lousy the critics on talksox had a field day regaling one and all with comments on just how much of a nitwit Farrell was. Then September rolled around, the bullpen got way better, and the Sox had a great month, good enough to win the tough AL East.
Yes, the lineup card can have an effect, so managers need to be willing to change things when it makes sense to do so. But the most effective lineups tend to be consistent ones, including platooning. I like arguing about lineups, but don't kid myself that there is a miracle cure if just the right guy/guys is/are in the right spots. Right now I kind of like that Betts leads off with the most dingers and rbi's and Bogie bats 3d with just 1 dinger and half as many rbi's. Why? Because it seems to be working.
Baserunning, I would argue, is partly on the coaches, but mostly on the ability of the players to assess--in split seconds, mind you--what is happening and what is possible and then to act on it just as quickly. You can't coach that or teach that. See Daniel Nava as exhibit 1 for the prosecution. He's smart, he's experienced, he's reasonably speedy, and he is a disaster on the base paths (or was with the Sox).
Bunting. Definitely an acquirable skill that is almost nonexistent on this team. Why? Because the statisticians have made a convincing case that bunting is counterproductive because it gives away outs. The bunt is a managerial tool which most teams simply take out of his tool bag, simple as that.
