Episode 4: Stats and Storytellers with Jonah Keri

August 25th, 2017

This is the first in a new recurring series called Stats and Storytellers. We’re excited to welcome Jonah Keri as our first guest. Our conversation was wide-reaching and really interesting. We talked about Jonah’s recent article about the Expos mascot, Youppi, getting ejected from a game back in 1989, touched on the stats behind why he thought Tim Raines deserved to be in the Hall of Fame. Jonah reflected on his time at BP (and elsewhere), and we had a great discussion about the ins and outs of writing about statistics.
