Scenario one:  Runners on 1st and 3rd, one out.  Non-power hitter A  grounds to shortstop for an inning ending double play.   

Scenario two:  Same situation.  Power hitter B hits ball in the air for an out.  Runner from 3rd scores.  Next hitter singles.  Following hitter strikes out. 

Let's say that these hitters come up 4 times in a game with the exact same scenarios.  A tends to hit the ball on the ground, B tends to hit the ball in the air.  Hitter B can strikeout three times and hit a homerun.  Or he can strikeout twice, homer and fly out.  He would drive in 3 or four runs in these cases.  Plus the inning is still alive in both cases.

When I watched the Braves last year, I saw an awful lot of hitter A's.  In the scenario I described, it seemed that they usually hit the ball on the ground (or struck out).  Since most hitters don't hit 400, they usually did something less than 2 for 4 in those situations.  But assuming that they did hit .400 they would be responsible for driving in 2 runs.  Again, that's with them hitting .400

This isn't based on stat analysis.  This is based upon my observation as a fan that watched a lot of games.  The Braves were a station to station team.  Not much speed.  Not much power.  Not much sucess in the scenarios that I described.

There is nothing wrong with a guy who might walk or might get a single.  The odds say that  it is hard to win when most of your players are that guy.
