When you compare Bailey to Odorizzi you see what the FO was seeing. Bailey actually has higher average velocity on his fastball, has a the split finger that really progressed late last year, and had success against Houston and NYY late in the year. I like Bailey over Perez for the simple fact that I think Bailey will listen. I don't think Perez followed instructions very well....seemed to go away from what made him successful early in 2019.
