Your Random BBA Graph of the week #2!

Post by **CTBrewCrew** » Sat Oct 12, 2019 4:50 pm

Was listening to Niles weekly podcast and couldn't believe how right he was when he talked about the explosion of stolen bases in the BBA between 2030 - 2035....WOW. Thanks again for the inspiration Niles! Once i get the historical individual player data - ill follow-up with some player DB stats.

Until then enjoy...

Something seems odd there. These charts would say our average success rate was only 50% or so prior to the big expansion...but I think it ran about 64-65%.

Definitely an interesting take, though.

You can click on points or select ranges from the graph and see specific years data

The top success rate being 31% seems wrong.

Since 1995 - thats the success rate per team

Sb / total attempts

Something's off. Here's Vancouver, what I assume is year by year data.

Post by **CTBrewCrew** » Sat Oct 12, 2019 8:18 pm

Yes - its the sum for each category per year for each team. (SB & CS)

Looking at Vancouver's data (same formula for all teams)

sb% = stolen bases / (stolen bases + caught stealing)

Stolen Base Attempts = (stolen bases + caught stealing)

Caught Stealing % is just the inverse of SB% - if you were successful 60% in SB% your CS% was 40%.

For the first line item in your screen shot is the 1995 team totals for VAN.

In 1995 Vancouver as a team attempted to steal 109 bases -- they were successful 64 times they failed 45 times.
In 2031 Vancouver as a team attempted to steal 509 bases -- they were successful 363 times they failed 146 times.

For whatever reason the leagues SB attempts sky-rocketed starting in 2029 to 2033 - then started to trend down again.

As a league if you sum up all the teams in the BBA last year they stole 4788 SB - that's an average of 159.6 SB each for the 30 teams.

Even as of last year (as a whole league) BBA C only threw out about 24% of all runners - that's like a 3 out of every 4 attempts your gonna get the base.

Even though SBA # are coming down some - Runners are being more successful in fewer attempts.

This is the graph I'm taking about. Is this SB success rate or CS rate?

Fixed -- i bass-ackwarded the calculation - thanks for staying on top of me....my QA department is lacking...

no problem! I really enjoy seeing these every week.

One of the issues I was having, too, is that the raw overall successful and failed SBA are being plotted on two different axis.

Post by **CTBrewCrew** » Sun Oct 13, 2019 7:36 am

Yeah - its a dual line (or axis) chart (Non-Synchronized). Its a good way to lets you interpret data on multiple Y axis for two values on the same chart that are related, but that would have different Y axis values.

Yeah, but the variance isn't that large, and plotting them on the same axis would give an immediate feel for how success rate has changed as well as rate of occurrence.
