Wainwright (0-1) took the loss against Arizona on Thursday, giving up three earned runs in just 3.2 innings while serving up four hits, walking four and striking out three.
It was a rough first start of the season for the veteran in his return from a hamstring injury, as Wainwright struggled with his control. Once one of the most dominant pitchers in the game, Wainwright had a 5.11 ERA in his 123.1 innings last year and hasn't posted elite marks over the course of a full season since 2014. At this point, he can't be trusted for fantasy purposes until he shows that he's regained his old magic for a sustained period of time.
