(What is this chart?)

NB: Fangraphs doesn't separate out defensive and baserunning mistakes like Jeff would, so Montero's not getting debited for his ill-fated attempt to reach home in the first inning. I'm not building a win expectancy spreadsheet just to figure out what the Jeff-standard numbers would be if you divvied up credit correctly, however, so Fangraph numbers are what you're getting. Sorry!
