Zack Greinke pitched the first several innings of Sunday’s Angels-Rangers game with his last name misspelled on the back of his jersey. As you can see in the screen shot above provided by Mock Session, Greinke’s last name was misspelled “Grienke.” After the mistake was pointed out, the Angels fixed things and Greinke returned with a jersey that had his last name spelled properly, but he still pitched for about an hour before that issue was solved. The jersey may have brought him some bad luck, because Greinke had his worst outing in five weeks. The Angels starter gave up four runs over the first three innings after going seven consecutive starts without allowing more than two runs. Believe it or not, this sort of mistake actually happens quite frequently.
