Wheeler (10-8) was tagged with the loss Thursday against Arizona after allowing six runs on seven hits and a walk across 6.2 innings, striking out seven.
Wheeler pitched a complete game against the Mets earlier this month, but his recent performances have left a lot to be desired with Thursday's outing not being any different. He has allowed at least four runs in three of his last four appearances and has posted a 4.34 ERA across 29 innings in that span.
