Bryce Harper showed exactly what it means to ‘flush it’ last night—making a mistake, moving on, and coming back the next inning with a huge home run. I first learned about the Flush-It Routine watching the 2004 College World Series, when Cal State Fullerton had a toilet in their helmet rack for players to physically “flush” their mistakes. The man behind it was Ken Ravizza—one of the pioneers of mental performance and someone I was incredibly fortunate to work with during my career with the Tampa Bay Rays. The lesson is simple: You can’t change the last play. But you can keep it from affecting the NEXT one.
