Arizona Diamondbacks
Mark Melancon landed on the injury report on April 29th with a Covid-19 issue. He tossed six shutout innings over his previous six games with no walks, three strikeouts, and four saves. Melancon has yet to blow a lead in a game this year. Ian Kennedy recorded three saves over the past week while looking better over his past seven innings (1.29 ERA and six strikeouts). However, his command (seven walks over 12 innings) has been a problem in multiple games this year.
