Handedness

[GATC]

If by chance anyone can help, I would appreciate it.

 

What is the best way to determine an individual players offensive ability vs RHP and LHP?

 

I'm thinking wRC+ and looking at the last 3 years of data vs. LHP and vs. RHP, respectively.

 

What about new players? I don't think this data is available on Fangraphs (minor league stats and wRC+ vs LHP / RHP).

Are you asking like... if they bat right or left handed? Because that's super easy to find...

If you're asking something else, I'm not getting it so you may have to elaborate.

Handedness, as in how "handy" or useful they are?

I'm looking to evaluate their overall offensive ability vs LHP and RHP (using something like wRC+). In particular new players that don't have much major league data.

Sounds like if a player is worth being platooned vs everyday. Last 3 years maybe, but it depends on plate appearances. Need a large enough sample size.

Yeah, agree. Is there any way to get this type of data from their minor league stats??

Both Fangraphs and Baseball reference provide RHP/LHP splits. There's splits tabs in both baseball reference and Frangraphs but they are not available for MiLB data. Also you should note that sadly neither Fangraphs or Baseball Reference provide regressed splits.

 

Basically what unregressed means is that the sample is too small to be considered normalized so to minimize SSS distortion you should assume average splits for whatever number of PAs are missing to normalize. Nox beats this drum a lot but until the major sites provide the regressed splits, I don't see what choice anyone has but to use the unregressed splits. I suppose to make him happy you should put an asterisk on any unregressed splits you quote.

Holly s***! What a gold mine.

Thanks. What do you/he consider too small a sample?

[GATC]

Too bad minorleaguecentral.com doesn't provide wRC/wRC+, I guess I'll switch to wOBA

Well I don't really have an opinion on the matter but apparently the normalized sample need to be quite large according to experts. Nox posted a Fangraphs link explaining it yesterday. I'll see if I can dig it up.

Cool. Googled "Regressed Platoon Splits Fangraphs" and found it immediately: http://www.fangraphs.com/blogs/estimating-hitter-platoon-skill/
