We recap the Oakland Athletics series that had quite a few moments, but also some shaky times. Will increase velocity help Lucas Giolito like it has for Dylan Covey? Will Sunday's performance be the spark for Yoan Moncada to catch fire? After four starts, how is Carlos Rodon progressing? 

Our guest is Jonathan Lee who reports from Charlotte on Eloy Jimenez's transition from AA to AAA, what Michael Kopech needs to overcome to get back on track, and the players we should pay more attention to in Charlotte.
