About This Page

The table above lists every Griffin Jax start that appeared in Bookie Bullies' daily MLB coverage. ERA shown is what the model used at that point in the season, not a retroactive value. The "Pick Result" column reflects whether a pick we made on Griffin Jax's team won, lost, or pushed. Pushes count separately. "Pending" means the game hasn't graded yet.

Frequently Asked Questions

How does the model rate Griffin Jax's starts?
Griffin Jax's starts are scored by FIP and xFIP (park-and-league-adjusted), recent form trend (last 3 starts ERA delta vs season), velocity drop penalty when last start had velo decline, home/road and day/night splits, opposing lineup xwOBA vs handedness, and pitcher H2H history vs the opposing team regressed at 50 TBF. The model also factors bullpen quality (in case Griffin Jax exits early), park factors, weather, and umpire tendencies.
Where can I find past picks involving Griffin Jax?
