I went to a MLB game earlier this week and noticed those graphics they display on the scoreboard that show what happened on each of the batter’s previous at-bats for that game. I can’t find an example by googling, but hopefully people know what I’m talking about. They look like pictures of baseball diamonds, and the symbols on them tell you what happened on that at-bat. I was furiously googling on my phone during the game, but couldn’t find any reference on decoding them.
There’s a number in the upper-right corner, which I assume represents the inning. There’s a code at the bottom which tells you what actually happened, some of which I know (like K for strikeout, BB for walk,) but others of which are a mystery to me (one during this game read “6-3.”) Then there’s an arc, which I assume shows where the ball went. Also, sometimes there appeared to be blue lines between the bases, and also the infield would be colored differently on some than on others.
There’s got to be a good reference site out there where you can read about what all this means. Anyone know?
The numbers are a basic part of baseball scoring. Each stands for a position - 1 is the pitcher, 2 is the catcher, 3-5 are the 1/2/3 basemen, 6 is the shortstop, 7-9 are the left/center/right fielders. So “6-3” means the batter grounded out, shortstop to first. A change of color on the basepath line shows how far the batter advanced during that inning. On paper, you’d fill that in with pencil.
They do this at Fenway, as each batter comes up they show his line for the game including the filling in the diamond for how many bases they reached. They also display a “Score that:” after most plays.
So in Arcite’s linked photo, if I’m reading it correctly the second time Brantley was at bat, in the 3rd, the 2nd baseman threw him out at 1st. Why does the red line run at an angle to the left of 1st, does that mean he’d turned the corner and was trying to get to 2nd?
I think that represents where the ball was hit. In the first inning it looks like he hit the ball directly to the first baseman. In the third inning he hit it to the 2nd baseman and the trajectory of the ball is the red line. They don’t add that line at Fenway were I’ve seen this type of display. We’d need to see a play where a batter got on base to verify.
I wish our stadium had them too, this is pretty cool and helpful. I’m sure teams keeps this data and use it to shift outfields, etc. Now even the casual fan can see why they’re doing that as it happens.
