FanGraphs Feature Focus: RosterResource Probable Pitchers

If you’ve looked at the team’s RosterResource page, you may have noticed that there’s an upcoming schedule table at the top that includes the potential pitchers over the next 10 days:
That’s all well and good if you only care about looking at one team, but if you’re a fantasy player, a roster freak, or just sick with baseball fever, Probables Grid is that little box of upcoming schedules that has been blown up.

Although the full Probables Grid will still only show you the next 10 days, the grid has several advantages for clicking on 30 team pages. (We believe that going more than 10 days on potential pitchers is like going 10 days on a weather forecast: our confidence in its accuracy always decreases.)
First, I’d be remiss if I didn’t mention again that exporting to Excel is a members-only feature. If you wanted to, say, easily find out how many pitchers, and which ones, are scheduled to start three in the next 10 days, that’s the best way to do it.

And I recently added a toggle at the top so you can easily flip back and forth between who the team on each line is starting and who the team is facing, which is also exported to Excel. The Excel exporter will only export any two tables you have displayed, not both at once.

While this is a specific feature we can use, I also wanted to highlight the data itself as part of this Feature Focus. We get all the starting pitcher information from Rotowire, which does a really good job of forecasting, and Jason Martinez and I write more as needed. But until the team officially announces the starters (usually one series at a time, right before the series begins), nothing is official. For example, the team might plan to give the starter an extra day off and install a local starter a week from now, but we don’t know that yet. Things change, and we update our opportunity data accordingly.
The openers throw another wrinkle in this, because teams don’t usually announce those until the day before the game or maybe the day of it. Those will appear on the Probabilities Grid and team pages with “OP:” for “opening pitcher,” before their name, and will always be accompanied by “PP” (“primary pitcher”) on the next line. Teams, of course, are not required to reveal their main striker, when he will enter the game, or how long he will play. That can, in some cases, make prediction difficult even on game day. Thus, user discretion is advised.
If you see a direct error based on something the team or reporter said, please let us know at rosters@fangraphs.com and we will correct it as soon as possible.
