After the Yankees trade for or sign a new player, fans often subject the new arrival to a trial period, during which they decide whether or not to embrace the new guy as a Yankee who belongs in the Bronx. The trial period can be especially tough for big names and guys with strong ties to a different team.
But every now and then, a new player will win over the fanbase very quickly and the new player seemingly becomes a true Yankee overnight. This has been the case with Anthony Rizzo. He joined the team just one week ago, and already Rizzo has made a big impression on fans.
