Neil Weinberg FanGraphs Q&A – 7/23/14

: Hey everyone, let me get you caught up.
My job here is primarily to serve as something of a Site Educator. This means that I’m responsible for providing resources to readers about our data, advanced metrics, and how to make use of the features available at the site. My Twitter handle is @NeilWeinberg44 and if you want to get in touch about these kinds of questions at times other than 3pm on Wednesdays, that’s where to find me. It’s my job, so take advantage of it. With that said, I will prioritize “how does this work?” and “what does this mean?” type questions during the chats, but feel free to ask regular questions about anything as well. Although if you’re here for fantasy advice or prospect talk, I’m probably less helpful than some of our writers. Think that’s it, queue is open and we’ll start at 3pm! |

Hi Neil. Welcome back. I’m trying to walkthrough the part 1 of the WAR calculation for hitters. Dave uses the example of 2008 Adrian Beltre. I can match the wRAA on the player page (3.5), but I don’t follow the park adjustment. Somehow I am supposed to take a 96 Safeco park factor and come up with a batting value of 5.9 for Beltre. Can you help with this? |

: This is probably too technical to walk you through in detail during a chat, but his wRAA is 3.5 and his Batting Runs are 4.8 for that year. I assume the values changed when we adjusted replacement level, so the exact values Dave and wrote about aren’t exactly correct.
I just did a very quick pen and paper calculation and got 4.7something. I’ll cover the specifics of all of these things as I update the glossary, but if you ever need specific clarifications, get me on Twitter. |

Q about defense stats: if a player robs a HR, does he automatically gets 1 run saved? does it go to 4 runs saved if the bases are loaded? |
| 3:02 |
: It depends on how difficult the play is. So basically, you care about how often the average defender would also rob that home run. Unfortunately, not as simple as +1 for solo HR robbing.
