Bunting is a lost art. In my youth, most of the smaller players were good bunters, and even some big guys were good at it (Cliff Johnson is an example). Granted, in those days, the smaller guys were 5' 7" and 140 pounds. Now most of the small guys are jacked, like Jose Altuve, and hit for power.
And I'm sure the stats say never give up an out, that 1st & 2nd with nobody out is better than 2nd & 3rd with one out. And that might be so, when they look at hitting stats -- three chances for an outfield base hit is better than two chances, especially when there are a lot of strikeouts nowadays. But late in close games, batters are facing the opposition's best pitchers, so batting averages go down, contact goes down, strikeouts go up. I think the chances for double plays is higher now. Guys don't always run hard out of the box, making them easier to double up . As Tinker said, there are a lot of ways to score a guy from 3rd with only one out, and while hoping the pitcher balks might not be the best strategy, good baserunners used to try to induce them.
During Dave Winfield's years with the Yankees, he rarely bunted, which allowed the 3B to play almost on the outfield grass. 5-6 bunts a year would have kept the opposition honest, and probably would have gotten him an extra 8-10 hits a year in addition to the bunts. With the shifts now, certainly every left handed hitter should learn to be proficient at bunting -- they're giving hits away with the 3B playing over by shortstop. In a close game, or when trailing by a few runs, it's an easy way to get on base. Righties don't have quite the same advantage, as the 1B has to be closer to the bag, but there are still opportunities when the left side of the infield is playing deep.
But I'm an old fart, so what do I know?
