Pitching prospect Nolan McLean will make his major league debut Saturday for the New York Mets, who are hoping the right-hander can provide a boost to a struggling rotation

There are many reasons as to why the Mets have collapsed, but their starting rotation is undoubtedly the biggest one. The Mets have struggled mightily to get any sort of length out of a starter not named David Peterson, and even Peterson failed to complete four innings his last time out and blew a 6-0 Met lead.

The Mets could use some big-time help, so who better to call upon than a guy occasionally called Cowboy Ohtani?
