Dr. Mike Sonne stops by to discuss red flags that are appearing both in Roberto Osuna's Stuff rating and his workload, as measured by Dr. Sonne's Fatigue Units statistic. He also discusses the Jays bullpen as a whole and how the stuff metric can be used to potentially show injuries. Greg and Josh then quickly discuss the nightmarish end to the Cubs series, Josh Donaldson's extreme hot streak, and goofy injuries before talking about the Golden Sombrero and the fastest pitch ever thrown. Finally, they answer listener questions and give out a Do Over to the MLB Umpires.
