how is possibly not scoring at all preferable to scoring at least one run? Isn't the aim in baseball to score the most runs possible?
Historically, in situations with 1 out and runners on first and third the team will score 1.17 runs. If you hit a sac fly (or a fielder's choice) and wind up with 2 outs and a runner on first, you score 1 run and expect to score an average of 0.23 more runs, so you improved your situation by about 0.06 runs. A decent result, just slightly above the average outcome. If you get a sac hit and wind up with a runner on 2nd and 2 out, you get your run and expect 0.33 more. Now you've improved your expected runs by .16. If you walk, no runs score, but with 1 out and the bases loaded you expect to score on average 1.57 runs. That's an improvement of 0.36 runs, or 0.2 runs better than the groundout and 0.3 runs better than the sac fly. Unless you
really need that first run - as in, as BL says, a walkoff situation, or maybe even if you need 1 to gain a lead or even the score in the late innings - the walk is the best of these 3 scenarios.
I should note here that this is not some sabrmetric mumbo jumbo. Those expected run values are based on historical data from 1984 to 1994. It's also worth pointing out that expected run values increase proportionally with offense. So when Edgar played, when there was more run scoring, the expected run values go up. That means you're giving up a little bit more than these expected run values estimates by taking an out for a run. During Edgar's prime it may have been about .05-.1 more runs more costly to sacrifice vs. walking than the older historical data suggests.
