The team issued a red flag on franchise ace Zack Wheeler when they pushed back his latest start due to some shoulder discomfort. Wheeler was able to pitch against the Rangers on Sunday, but his velocity was down and he made some uncharacteristic mistakes as he struggled with control as well.

The Phillies say Zack Wheeler underwent an MRI after he reported right shoulder stiffness and will push his next start back two days.

The Phillies’ ace has allowed three or more runs in just six of 22 starts this year, but three of those starts have come in the past month.
