Let me carry this scenario to a more concrete and realistic conclusion. I will address why Fred could be right, but when reality is applied, he is wrong. In an average "perfect" game with no sacrifices and a perfect defense on each team, runners aren't able to advance more than one base for the singles team, and 2 bases for the doubles team, teams get all their hits in a row in each inning, then 3 outs:
Doubles team will have 31.5 hits, rounding to 32 because I have a sunny outlook on life. That averages to 4.5 hits an inning, which will guarantee 3 runs per inning, and I'm going to add 3 runs to the total because I am going to string the .5 hits together to score runs and I'm rounding up to 4 hits. Yeah, I know, now my team is batting .615. Big whoopity do.
Doubles team will score 24 runs total, stranding 7 runners.
Singles team will get 7 hits per inning, scoring 4 because it takes 4 hits to score the first run. (My perfect defense will get the out at home every time, even if it's in the air there are no sacrifices)
Singles team will score 28 runs.
Seems like singles team wins every time, right? I mean, really, you could technically string all the hits together in one inning for both teams, and the score would like 46-16 for the singles team, you could just strike out the rest of the game, and we can go drink beer after the 3rd inning.
But we don't live in this little fantasy Fred world, do we? This assumes no HRs can be hit. Fred wants to assume some DBOs, which do not matter in this scenario because sacrifices aren't happening, so a DBO means nothing. Sacrifices are subjective to what kind of out is being made, so I will not include them in the discussion for simplicity's sake, but I will talk about them later cuz SOMEBODY will surely ***** about it. Errors are also not being made because the defense is perfect, so they have no bearing either.
Even in this "perfect" scenario, the singles team only outscored the doubles team by 4 runs over 7 innings, but took 18 more ABs to do it. Gets the job done, but hardly efficient.
Let's add some reality:
Since the only people on SBF are uber-competitive, HR-hitting superjocks, let's add some slugging percentage to this equation. I've severely limited my power-hitting team by limiting them to doubles because I want them to get down on the level with the little people as close as possible. Now, I'm not being a nice guy anymore. Since we're playing the only thing that matters, competitive tourneys, let's give the power team 4 HRs. And because I'm not being nice anymore, they are all two-run shots at the end of my string of hits. I just added 4 more runs and took away 4 guys being LOB.
Now the score is: Doubles 28, Singles 28. OH NO!! We have a tie game, WTF!!! Make it a 6 HR or 10 HR limit for you SBF gods of the diamond, and singles team loses every time.
But wait, there's more!!
Since we're playing perfect defense with no errors, if you want to give my team all DBOs after the HR limit cuz we're douchebags and like to show you up, go right ahead, those DBOs still don't matter. In reality, no team is going to get all their hits in a row. my perfect defense will turn at least one DP each inning. Of course, we are going to get the lead runners at home and 3rd in the DP cuz we're perfect, although that really doesn't matter. That reduces the singles team score by 1 run for every DP that I turn, because the singles team now has to get 2 more hits to generate the next run they score. We're being nice to the singles guys, so we only turn a DP every other inning. You've now reduced the singles team score by at least 3 runs.
Sound unrealistic? I've got a perfect defense that can choose whatever forceout they want, which is a hell of a lot easier than trying to throw someone out for a double play.
Of course I'm being intelligently facetious here. No defense is perfect, HOWEVER, the statistical probability of turning a DP is phenomenally higher when you have 3 forceouts to choose from instead of none. I'll go you one further. DBOs over the fence would actually be helpful in this situation because if ALL of my outs are DBOs, I have effectively eliminated the singles team chance to turn a DP and reduce my team's scoring changes.
Final score is Doubles 28, Singles 25
