With Phillies ace Zack Wheeler on the IL with blood clots, what does that mean and how have other pitchers fared?

Losing Wheeler is a massive blow. If we were to create a list of players the team could ill afford to lose as they chase the World Series trophy, he is at the top. But lost he is and the team is going to have to adjust. They still have the talent to get deep into the postseason. It just got a little bit more difficult.

Philadelphia Phillies right-hander Zack Wheeler has been placed on the injured list after a blood clot was discovered in his right upper extremity near his shoulder, according to The Athletic's Charlotte Varnes.
