BESR bats make a difference

D2:
Runs Scored 2011 = 5.78 per game Runs Scored 2010 = 6.75 per game
ERAs 2011 = 5.04 per game ERAs 2010 = 6.08 per game

D3:
Runs Scored 2011 = 5.90 per game Runs Scored 2010 = 7.08 per game
ERAs 2011 = 5.13 per game ERAs 2010 = 6.30 per game

Seems likely that D1 "runs scored" figures are transposed. Otherwise, how do you explain negative unearned runs per game (i.e., ERA is greater than average runs per game) in 2010?

D2 and D3 show roughly .75 unearned runs per game in both '10 and '11. If you switch the D1 runs scored figures, they'd show roughly 1 unearned run per game both years.

I think looking at one year of numbers isn't enough to prove the bats are that effective. I'll agree it's going to show the same in long-term numbers, but let's not jump the gun too quickly.

Also agree about one year. Batters will adjust and improve probably not back to pre BBCOR HR numbers but teams will adjust to style of play with the bat too

Good catch. I should have checked the data prior to posting it. The stuff I posted was given to me by a local college assignor. I went to the NCAA Arbiter site just now to verify and found the mistake. I gave you the credit for finding it when I sent him the news.

The NCAA site also has a qualifier below the stats, "Averages are per game and per team." I can see why he included it but was not confused.

One year of data is not perfect but almost every coach I encountered agreed that the BBCOR bats made a huge difference. Slap shots become manageable groundballs. The 5'5" second baseman wasn't hitting bombs and the pitcher had time to react.

Not that I'm a credit hound ... but for the record I brought it up first.
