After facing Chris Paddack, Dinelson Lamet and Garrett Richards, the Diamondbacks drop down in class today drawing Joey Lucchesi. He has a career record of 18-19 with a 4.14 ERA and has yet to prove he can be an above average starter. 
Right-handed Luke Weaver was a star holding 10 of 11 opponents to three runs or fewer last season before being sidelined until the final week of the season due to an elbow injury. 
The Padres have lost 20 of the past 26 times they've gone against a righty starter.
