Zack Wheeler went on the injured list Monday and the Giants swept a doubleheader, emphasizing how sensitive the starting pitching market is and how it can shift almost daily with every pain and gain between now and July 31.
The twists and turns obviously have not been good for the Mets. They can talk boldly that Wheeler will be back to make one or two starts before the deadline. But a shoulder injury is going to lower the return even if Wheeler makes it back. And Wheeler represented the item that would bring the greatest return among those whom the Mets are overtly shopping.
